Operation
Caution Do not operate the system if the fan tray assembly is removed or if it is not functioning properly. An overtemperature condition can cause severe equipment damage or an unscheduled system shutdown.
Depending on the ambient conditions, the system optimises the fan-speed for temperature and pressure and maintains the minimum fan speeds and temperatures that the chassis requires. Accordingly, the fan tray's internal controller operates in a normal mode and a Network Equipment-Building System mode (NEBS mode).
Cisco Catalyst 9400 Series Switches Hardware Installation Guide 17
High Availability
Product Overview
· In the normal mode--the controller optimizes fan-speed for temperature and pressure. · In the NEBS mode--the controller responds more aggressively, to maintain proper cooling for installations
with high airflow impedance. When the fan tray operates in this mode, there may be increased noise levels due to increased fan speeds. You can also manually set the fan tray to operate in the NEBS mode.
High Availability
To ensure high availability, the system is designed to respond to fan failures by either minimising impact or by compensating and operating at a worst case scenario specification.
· If a single fan fails, the remaining fans in the row compensate with increased speed. · If two or more fans fail, the entire fan tray operates at full speed after one minute. Further, the fan tray
must be replaced. The individual fans are not field replaceable, you must replace the fan tray. · If the temperature sensor fails or communication with the temperature sensor fails, the worst case operating
temperature is assumed. · If the pressure sensor fails or communication with the pressure sensor fails, the worst case operating
pressure is assumed.
Thresholds, Alarms, and Abnormal Acoustic Conditions
Under normal operating conditions, when none of the temperature alarms have been triggered, hardware controls fan speed. If any of the system temperature alarms are triggered, software takes fan speed control from hardware. Refer to the System Management section of the software configuration guide for more information. When the fan tray operates at full speed, increased noise levels may be expected. The fan tray may operate at full speed in these circumstances:
· If the fan tray is not installed correctly · When operating in the NEBS mode · If two or more fans have failed · If the STATUS LED remains red for more than one minute · If there is a hardware failure · If the software watchdog timer is triggered

Product Overview
Power Supply Module Overview
The power button has two modes of operation, which are described below. Press the power button for 10 seconds to toggle between modes; the LOCATE LED blinks for three seconds when you do.
· Auto-on: When in this mode, the power supply module automatically starts or restarts on application or restoration of DC input power. This is the default mode.
For NEBS compliance, the power button must be in the auto-on mode. When power is restored after a power failure, the power supply module recovers automatically.
· Protected: When in this mode, if the DC power source output voltage is zero, or drops out for more than three seconds, you must press the power button for two seconds, to restore operation.
· Has dual DC inputs.
Each input has an independent, isolated circuit. -A and +A form one DC-input; +B and -B form another. Each DC input can be powered either from separate sources, or a suitable single source. The module has one operational mode as a function of both inputs receiving power. When both the inputs are active, a regulated 55-VDC PoE-compliant main output and 3.3-VDC standby output is provided.
· Has DC-input reversal protection such that the unit will survive DC-input reversal up to the full input voltage rating.
· Supports redundant and combined configuration modes. A single (nonredundant) or a dual (redundant) power supply configuration, can support the following loads:
Input Voltage (in Volts DC)
Output Power with C9400-PWR-3200DC (in Watts)
40-72 VDC (with an extended range to 75 VDC) 3200 W
A voltage differential between inputs is acceptable, as long as the value is within the above range. For example, one DC input can have an input voltage of 40 VDC and the other, 75 VDC.
· Has a built-in, front-facing, passive RFID tag that uses Ultra High Frequency (UHF) RFID technology and requires an RFID reader with compatible software.

Power Supply Modes
Cisco Catalyst 9400 Series Switches offer redundant and combined configuration modes for power supplies.
The number of power supply modules installed and the system load determine the power level that the system expects to draw from each power supply module, and consequently, the power supply mode that will be suitable. To calculate, or estimate a system's power budget, and to determine power supply requirements for a specific PoE configuration, use the Cisco Power Calculator.
To configure a power supply mode, enter the power redundancy-mode command in global configuration mode. If you do not configure a mode, the default mode is applicable.
Combined Mode
This is the default power supply mode.
The system operates on one to eight power supply modules. The power available to the system is the sum of power outputs of all the power supply modules in the chassis. All available power supply modules are active, share power, and can operate at up to 100 percent capacity.
Caution
When operating in combined mode, if any of the modules fail, all remaining operational power supply modules increase their output. If the output power does not meet the system requirements and the power supply autolc shutdown command is disabled, all the operational power supply modules may get overloaded and go into overcurrent shutdown. All system power is then lost.
Redundant Mode In a redundant configuration, a given power supply module can either be active, or in standby:
· An active power supply module is powered on, and provides output power. All the active modules in a chassis always attempt to share the load.
· A standby power supply module is powered on, but asleep, and can switch to active when required. When in standby mode, the power supply module's OUTPUT LED is blinking green.
To ensure high availability, the system is designed to respond to failure as follows: · If all the available power supply modules are active, the operational power supplies continue to share current equally. Note that the load on the available power supplies would have increased.
· If standby power supply modules are available, the minimum number of power supply modules needed to power the load switch to active.
When configuring a redundant mode, you have these options: an n+1 or an n+n redundant mode. N+1 Redundant Mode
Cisco Catalyst 9400 Series Switches Hardware Installation Guide 23
Power Supply Module Installation Considerations
Product Overview
N is the number of active power supply modules and can be one to seven power supply modules on a seven-slot or a ten-slot chassis, and one to three power supply modules on a four-slot chassis. +1 is the power supply module reserved for redundancy, and must be configured as the standby module (use the power redundancy-mode command in global configuration mode). The default standby power supply slot on a seven-slot or a ten-slot chassis is eight. The default standby power supply slot on a four-slot chassis is four. To designate a different slot as standby, use the power redundancy-mode command in global configuration mode. N+N Redundant Mode N number of power supply modules are configured as active, and n number of power supply modules are configured as standby. To configure standby power supply modules, use the power redundancy-mode command in global configuration mode. For detailed software configuration information including examples, see the required version of the software configuration guide. In the guide, go to Contents System Management Environmental Monitoring and Power Management.
Power Supply Module Installation Considerations
Warning This unit might have more than one power supply connection. All connections must be removed to de-energize the unit. Statement 1028
Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030
Warning No user-serviceable parts inside. Do not open. Statement 1073
Note While the installation of power supplies of different capacities in the same chassis is supported, it is not an optimal use of total system power in a redundant mode.
When installing power supply modules, ensure that the following conditions are met:
AC input Only If you plan to install only AC-input power supply modules, you must meet these conditions in the context of the N+1 redundant mode, or N+N redundant mode, or combined mode:
· All the installed power supply modules must be of the same capacity. For example, all the installed modules are C9400-PWR-2100AC.
· All the installed power supply modules must have the same AC-input voltage level.
Cisco Catalyst 9400 Series Switches Hardware Installation Guide 24
Product Overview
Power Supply Module Installation Considerations
For example, all the power supply modules have an AC-input voltage of 220 VAC, or an AC-input voltage 110 VAC.
AC Input and DC Input with N+1 Redundant Mode or Combined Mode If you plan to install a mix of AC-input and DC-input power supply modules, you must meet these conditions in the context of the N+1 redundant mode or combined mode:
· All the installed power supply modules must be of the same capacity. For example, a mix of C9400-PWR-3200AC and C9400-PWR-3200DC are installed.
· All the installed AC-input power supply modules must have an AC-input voltage of 220 VAC.
AC Input and DC Input with N+N Redundant Mode If you plan to install a mix of AC-input and DC-input power supply modules, you must meet these conditions in the context of the N+N redundant mode:
· All the power supply modules that are configured as active must be of the same type; all the modules that are configured as standby must be of the same type. (The type refers to AC input and DC input). For example, all the installed active power supply modules are C9400-PWR-2100AC, all the installed standby power modules are C9400-PWR-3200DC.
· All the installed AC-input power supply modules in the chassis must be of the same capacity and have the same input voltage level. Continuing with the above example, all the active power supply modules are C9400-PWR-2100AC, and have an input voltage of 115 VAC.
· All the installed DC-input power supply modules must be configured as standby. Continuing with the above example, all the installed C9400-PWR-3200DC modules are configured as standby.
· If power supply modules of different capacities are installed, the higher capacity modules must be configured as standby. Continuing with the above example, the 3200 W module is the higher capacity module and all installed C9400-PWR-3200DC modules are configured as standby.
Note Regardless of the type of power supply module installed (whether only AC input, or only DC input, or a mix of both types), in the context of the N+N redundant mode, ensure the following: · When transitioning or switching over to the N+N mode (from any other mode), there must be no change in the power consumption budget during the transition period. · Total standby output power must be greater than or equal to the total active output power (total standby output power > or = total active output power). This ensures that the system continues to provide redundancy at the time of a switchover.

Site Requirements
Planning a proper location for the switch and layout of the equipment rack or wiring closet is essential for successful system operation. These sections describe some of the basic site requirements that you should be aware of as you prepare to install your switch, including the following:
· Environmental factors can adversely affect the performance and longevity of your system. · Install the switch in an enclosed, secure area, ensuring that only qualified personnel have access to the
switch and control of the environment. · Equipment that is placed too closely together or that is inadequately ventilated may cause system
over-temperature conditions, leading to premature component failure. · Poor equipment placement can make chassis panels inaccessible and difficult to maintain. · The switch requires a dry, clean, well-ventilated, and air-conditioned environment. · To ensure normal operation, maintain ambient airflow. If the airflow is blocked or restricted, or if the
intake air is too warm, an over-temperature condition may occur. The switch environmental monitor may then shut down the system to protect the system components. · Multiple switches can be rack mounted with little or no clearance above and below the chassis. However, when mounting a switch in a rack with other equipment, or when placing it on the floor near other equipment, ensure that the exhaust from other equipment does not blow into the air intake vent of the switch chassis. · If the switch supports 90W PoE, the existing cabling in the building may not be suitable for the switch installation. Reassess the cable plan with a qualified personnel. For more information, see the Cabling Requirements section in this document.
Cisco Catalyst 9400 Series Switches Hardware Installation Guide 27
Temperature
Preparing for Installation
Temperature
Temperature extremes may cause a system to operate at reduced efficiency and cause a variety of problems, including premature aging and failure of chips, and failure of mechanical devices. Extreme temperature fluctuations may also cause chips to become loose in their sockets. Observe the following guidelines:
· Ensure that the system is operating in an environment that is-- · 27 to 109 °F ( -5 to +45 °C) up to 6000 feet (1800m) · 27 to 104 °F (-5 to +40 °C) up to 10000 feet (3000m)
· Ensure that the chassis has adequate ventilation. · Do not place the chassis within a closed-in wall unit or on top of cloth, which can act as insulation. · Do not place the chassis where it will receive direct sunlight, particularly in the afternoon. · Do not place the chassis next to a heat source of any kind, including heating vents. · Do not operate the system if the fan assembly is removed or if it is not functioning properly. An
overtemperature condition can cause severe equipment damage or an unscheduled system shutdown. · Adequate ventilation is particularly important at high altitudes. Make sure that all the slots and openings
on the system remain unobstructed, especially the fan vent on the chassis. · Clean the installation site at regular intervals to avoid buildup of dust and debris, which may cause a
system to overheat. · If system is exposed to abnormally low temperatures, allow a two hour warm up period, in ambient
temperature no lower than 32°F (0 °C) before turning on.
Failure to observe these guidelines may damage the chassis' internal components.
Air Flow
The switch is designed to be installed in an environment where there is a sufficient volume of air available to cool the supervisor engines, modules, and power supplies. If there are any constraints with regard to the free flow of air through the chassis, or if the ambient air temperature is elevated, the switch environmental monitor may then shut down the system to protect the system components.
To maintain proper air circulation through the switch chassis, we recommend that you maintain a minimum space of 6 inches (15 cm) between a wall and the chassis and power supply unit air intakes or a wall and the chassis and power supply unit hot air exhausts. In situations where the switch chassis are installed in adjacent racks, you should allow a minimum space of 12 inches (30.5 cm) between the air intake of one chassis and the hot air exhaust of another chassis. Failure to maintain adequate spacing between chassis may cause the switch chassis that is drawing in the hot exhaust air to overheat and fail.
Figure 4: Air Flow Direction - Cisco Catalyst 9400 Series Switches
The figure shows the chassis and power supply air flow directions in a Catalyst 9407R Switch. The same air flow direction applies to all Cisco Catalyst 9400 Series Switches.

If you are installing your switch in an enclosed or partially enclosed rack, we strongly recommend that you verify that your site meets the following guidelines:
· Verify that there is a minimum of 6 inches (15 cm) of clearance between the sides, front, and back of any enclosure, and both the chassis air intake grill and the chassis air exhaust grill along with the power supply unit intakes and exhausts.
Do not use fully closed cabinets or open racks with solid side panels, unless they meet the 6 inch clearance requirements with respect to chassis intake and exhaust vents, or unless the sides incorporate sufficient venting holes.
The upright columns of a relay rack may have less than the recommended side spacing - provided there are substantial cut-outs, holes, or vents in the structure to allow adequate air flow through the chassis. For two-post racks with solid uprights, the recommended maximum column depth for unrestricted air flow is 5 inches (13 cms) for a 23-inch rack and 4 inches (10 cms) for a 19-inch rack.
· Verify that the ambient air temperature within the enclosed or partially enclosed rack is within the chassis operating temperature limits. After installing the chassis in the rack, power up the chassis and allow the chassis temperature to stabilize (approximately 2 hours).
Measure the ambient air temperature at the chassis air intake grill by positioning an external temperature probe 1 inch (2.5 cm) away from the chassis left side, and centered on the chassis both horizontally and vertically.
Cisco Catalyst 9400 Series Switches Hardware Installation Guide 29
Humidity
Preparing for Installation
Measure the ambient air temperature at the power supply unit air intake grill by positioning an external temperature probe 1 inch (2.5 cm) away from the chassis front, centered on the power supply unit section located above the card slots.
· If the ambient intake air temperature is less than 109°F (45°C) at altitudes of 6,000 feet and below, the rack meets the intake air temperature criterion. At altitudes above that threshold and up to 10,000 feet (3000 m), the air intake should not exceed 104°F (40°C).
· If the ambient intake air temperature exceeds this recommendation, the system may experience minor temperature alarms and increase fan speeds in response.
· If the ambient intake air temperature equals or is greater than 131°F (55°C), the system may experience a major temperature alarm with maximum fan speeds in response. If ambient temperature continues to increase, system will respond with protective shut down.
· Plan ahead. A switch that is currently installed in an enclosed or partially enclosed rack might meet ambient air temperature and air flow requirements at present. However, if you add more chassis to the rack or more modules to a chassis in the rack, the additional heat generated might cause the ambient air temperature at the chassis or power supply unit inlets to exceed recommended conditions which may trigger thermal alarms.
If installation conditions for inlet temperature and airflow are marginal or not fully met, activate the fan tray's NEBS mode, which has more aggressive programming to address restricted spacing and elevated ambient temperatures. This should result in reduced thermal alarms along with greater acoustic noise and increased power consumption associated with higher fan speeds.
Humidity
High-humidity conditions may cause moisture to enter the system, and cause corrosion of internal components and degradation of properties such as electrical resistance, thermal conductivity, physical strength, and size. Extreme moisture buildup inside the system may result in electrical short circuit, which may cause serious damage to the system. Each system is rated for storage and operation in 10 to 95 percent relative humidity, non-condensing with a humidity gradation of 10 percent per hour. Buildings in which climate is controlled by air-conditioning in the warmer months and by heat during the colder months usually maintain an acceptable level of humidity for system equipment. However, if a system is located in an unusually humid location, a dehumidifier should be used to maintain the humidity within an acceptable range.
Altitude
Operating a system at high altitude (low pressure) reduces the efficiency of forced and convection cooling and may result in electrical problems related to arcing and corona effects. This condition may also cause sealed components with internal pressure, such as electrolytic capacitors, to fail or perform at reduced efficiency.
Dust and Particles
Fans cool power supplies and system components by drawing in room-temperature air and exhausting heated air out through various openings in the chassis. However, fans also ingest dust and other particles, causing contaminant buildup in the system and increased internal chassis temperature. A clean operating environment can greatly reduce the negative effects of dust and other particles, which act as insulators and interfere with the mechanical components in the system. The standards listed below provide guidelines for acceptable working environments and acceptable levels of suspended particulate matter:
Cisco Catalyst 9400 Series Switches Hardware Installation Guide 30
Preparing for Installation
Air Quality
· National Electrical Manufacturers Association (NEMA) Type 1 · International Electrotechnical Commission (IEC) IP-20
Air Quality
Dust is everywhere and often invisible to the naked eye. It consists of fine particles in the air that originate from various sources, such as soil dust lifted by weather, from volcanic eruptions, or pollution. Dust at an installation site may contain small amounts of textile, paper fibers, or minerals from outdoor soil. It may also contain natural contaminants, such as chlorine from the marine environment and industrial contaminants such as sulfur. Ionized dust and debris are dangerous and get attracted to electronic equipment.
The accumulation of dust and debris on electronic equipment has the following adverse effects:
· It increases the operating temperature of the equipment. According to the Arrhenius effect, an increase in the operating temperature leads to a decrease in reliability and life of the equipment.
· The moisture and corrosive elements that are present in the dust can corrode the electronic or mechanical components and cause premature board failure.
These adverse effects are further accelerated by the presence of fans in the data networking equipment that ingest dust and other particles into the equipment. Higher the volume of air that is generated by the fans for cooling, the higher the quantity of dust and particulates that get deposited and trapped inside the equipment. Remove or minimize the presence of dust and particulates at the installation site by following the guidelines mentioned in ANSI 71-04-2013 regulations.
Note In addition to the guidelines mentioned in in ANSI 71-04-2013 regulations, follow all applicable guidelines as per site conditions to remove or minimize other contaminants.
Corrosion
Corrosion is a chemical reaction that occurs between electronic components and gases which results in metal deterioration. Corrosion attacks edge connectors, pin connectors, IC plug-in sockets, wirewraps, and all other metal components. Depending on the type and concentration level of the corrosive gases, performance degradation of the components occurs either rapidly or over a period of time. It also leads to blocked currents, brittle connection points, and overheated electrical systems. Corrosion by-products form insulating layers on circuits and causes electronic failure, short circuits, pitting, and metal loss.
A type of corrosion known as creep corrosion, that primarily affects PCBA (Printed Circuit Board Assembly) occurs when the PCBA is subjected to a harsh, and sulfur-rich (hydrogen sulfide) end-use environment over a prolonged period of time. The corrosion begins on certain exposed metals, such as copper and silver, and then creeps along the remaining metal surface either causing electrical short circuits or creating holes. Creep corrosion also occurs on electronic components such as resistors and PCBs.
To prevent corrosion, remove or minimize the presence of dust and particulates at the installation site by following the guidelines mentioned in ANSI 71-04-2013 regulations.
Cisco Catalyst 9400 Series Switches Hardware Installation Guide 31
EMI and Radio Frequency Interference Figure 5: A PCB with Corrosion on its Metal Contacts
Preparing for Installation
EMI and Radio Frequency Interference
Electro-Magnetic interference (EMI) and radio frequency interference (RFI) from a system can adversely affect devices such as radio and television (TV) receivers operating near the system. Radio frequencies emanating from a system can also interfere with cordless and low-power telephones. Conversely, RFI from high-power telephones can cause spurious characters to appear on the system monitor. RFI is defined as any EMI with a frequency above 10 kilohertz (kHz). This type of interference can travel from the system to other devices through the power cable and power source, or through the air in the form of transmitted radio waves. The Federal Communications Commission (FCC) publishes specific regulations to limit the amount of EMI and RFI emitted by computing equipment. Each system meets these FCC regulations. To reduce the possibility of EMI and RFI, follow these guidelines:
· Always operate the system with the chassis covers installed. · Ensure that all chassis slots are covered by a metal filler bracket and that an unused power supply bay
has a metal cover plate installed. · Ensure that the screws on all peripheral cable connectors are securely fastened to their corresponding
connectors on the back of the chassis. · Always use shielded cables with metal connector shells for attaching peripherals to the system.
Cisco Catalyst 9400 Series Switches Hardware Installation Guide 32
Preparing for Installation
Shock and Vibration
When wires are run for any significant distance in an electromagnetic field, interference can occur between the field and the signals on the wires. This fact has two implications for the construction of plant wiring:
· Bad wiring practice can result in radio interference emanating from the plant wiring.
· Strong EMI, especially when it is caused by lightning or radio transmitters, can destroy the signal drivers and receivers in the chassis, and even create an electrical hazard by conducting power surges through lines into equipment.
Note To predict and provide a remedy for strong EMI, consult experts in RFI.
If you use twisted-pair cable in your plant wiring with a good distribution of grounding conductors, the plant wiring is unlikely to emit radio interference. If you exceed the recommended distances, use a high-quality twisted-pair cable with one ground conductor for each data signal when applicable.
If the wires exceed the recommended distances, or if wires pass between buildings, give special consideration to the effect of a lightning strike in your vicinity. The electromagnetic pulse caused by lightning or other high-energy phenomena can easily couple enough energy into unshielded conductors to destroy electronic devices. If you have had problems of this sort in the past, you may want to consult experts in electrical surge suppression and shielding.
Warning
The intra-building ports (Copper Based Ethernet Ports) of the equipment or subassembly is suitable for connection to intra-building or unexposed wiring or cabling only. The intra-building ports of the equipment or subassembly MUST NOT be metallically connected to interfaces that connect to the Out Side Plant (OSP) or its wiring for more than 6 meters (approximately 20 feet). These interfaces are designed for use as intra-building interfaces only (Type 2, 4, or 4a ports as described in GR-1089) and require isolation from the exposed OSP cabling. The addition of Primary Protectors is not sufficient protection in order to connect these interfaces metallically to an OSP wiring system.
Shock and Vibration
The equipment complies with the Earthquake, Office, and Transportation Vibration, and Equipment Handling Criteria of GR-63-CORE.
Power Source Interruptions
Systems are especially sensitive to variations in voltage supplied by the AC power source. Overvoltage, undervoltage, and transients (or spikes) can erase data from memory or even cause components to fail. To protect against these types of problems, power cables should always be properly grounded. Also, place the system on a dedicated power circuit (rather than sharing a circuit with other heavy electrical equipment). In general, do not allow the system to share a circuit with any of the following:
· Copy machines
· Air conditioners
· Vacuum cleaners
· Space heaters
Cisco Catalyst 9400 Series Switches Hardware Installation Guide 33
System Grounding
Preparing for Installation
· Power tools · Teletype machines · Laser printers · Facsimile machines · Any other motorized equipment
Besides these appliances, the greatest threats to a system's power supply are surges or blackouts that are caused by electrical storms. Whenever possible, turn off the system and peripherals, if any, and unplug them from their power sources during thunderstorms. If a blackout occurs--even a temporary one--while the system is turned on, turn off the system immediately and disconnect it from the electrical outlet. Leaving the system on may cause problems when the power is restored; all other appliances left on in the area may create large voltage spikes that may damage the system.
System Grounding
Warning When installing or replacing the unit, the ground connection must always be made first and disconnected last. Statement 1046
Warning Use copper conductors only. Statement 1025
You must install a system ground as part of the chassis installation process. Chassis installations that rely only on the AC third-prong ground are insufficient to adequately ground the systems. Proper grounding practices ensure that the buildings and the installed equipment within them have low-impedance connections and low-voltage differentials between chassis. When you install a system ground, you reduce or prevent shock hazards, chances of equipment damage due to transients, and the potential for data corruption. Without proper and complete system grounding, you run the risk of increased component damage due to ESD. Additionally, you have a greatly increased chance of data corruption, system lockup, and frequent system reboot situations by not using a system ground.
Caution Installations that rely solely on system grounding that uses only an AC third-prong ground run a substantially greater risk of equipment problems and data corruption than those installations that use both the AC third-prong ground and a properly installed system ground.
The following table lists some general grounding practice guidelines.

Environment
Electromagnetic Noise Grounding Recommendations Severity Level
Commercial building is subjected to High direct lightning strikes.
For example, some places in the United States, such as Florida, are prone to more lightning strikes than other areas.
All lightning protection devices must be installed in strict accordance with manufacturer recommendations. Conductors carrying lightning current should be spaced away from power and data lines in accordance with applicable recommendations and codes. Best grounding practices must be closely followed.
Commercial building is located in an area where lightning storms occur frequently, but is not prone to direct lightning strikes.
High
Best grounding practices must be closely followed.
Commercial building contains a mix Medium to High of information technology equipment and industrial equipment, such as welding.
Best grounding practices must be closely followed.
Existing commercial building is not Medium subject to natural environmental noise or man-made industrial noise. This building contains a standard office environment. This installation has a history of malfunction due to electromagnetic noise.
Best grounding practices must be closely followed. Determine source and cause of noise if possible, and mitigate as closely as possible at the noise source or reduce coupling from the noise source to the victim equipment.
New commercial building is not subject Low to natural environmental noise or man-made industrial noise. This building contains a standard office environment.
Best grounding practices should be followed as closely as possible. Electromagnetic noise problems are not anticipated, but installing a best-practice grounding system in a new building is often the least expensive route, and the best way to plan for the future.
Existing commercial building is not Low subject to natural environmental noise or man-made industrial noise. This building contains a standard office environment.
Best grounding practices should be followed as much as possible. Electromagnetic noise problems are not anticipated, but installing a best-practice grounding system is always recommended.
Cisco Catalyst 9400 Series Switches Hardware Installation Guide 35
Maintaining Safety with Electricity
Preparing for Installation
Note In all situations, grounding practices must comply with Section 250 of the National Electric Code (NEC) requirements or local laws and regulations. A 6 AWG grounding wire is preferred from the chassis to the rack ground or directly to the common bonding network (CBN). The equipment rack should also be connected to the CBN with a 6 AWG grounding wire.
Note Grounding lugs must be installed on the location marked on the chassis only.
Note Always ensure that all of the modules are completely installed and that the captive installation screws are fully tightened. In addition, ensure that all the I/O cables and power cords are properly seated. These practices are normal installation practices and must be followed in all installations.
Maintaining Safety with Electricity
When working on electrical equipment, follow these guidelines: · Do not work alone if potentially hazardous conditions exist anywhere in your work space. · Never assume that power is disconnected from a circuit; always check the circuit before working on it. · Look carefully for possible hazards in your work area, such as damp floors, ungrounded power extension cables, frayed or damaged power cords, and missing safety grounds. · If an electrical accident occurs, proceed as follows: · Use extreme caution; do not become a victim yourself. · Disconnect power from the system. · Seek medical attention, if necessary.
· Use the product within its marked electrical ratings and product usage instructions. · Install the product in compliance with local and national electrical codes. · If any of the following conditions occur, contact the Cisco Technical Assistance Center:
· The power cable or plug is damaged. · An object has fallen into the product. · The product has been exposed to water or other liquids. · The product has been dropped or shows signs of damage. · The product does not operate correctly when you follow the operating instructions.
Cisco Catalyst 9400 Series Switches Hardware Installation Guide 36
Preparing for Installation
Preventing ESD Damage
· Use the correct external power source. Operate the product only from the type of power source indicated on the electrical ratings label. If you are not sure of the type of power source required, consult a local electrician.
· For AC-input power supply modules, you have been provided with one or more power cables with your chassis power supply that are intended for use in your country, based on the shipping location. Should you need to purchase additional power cables, ensure that they are rated for the product and for the voltage and current marked on the product's electrical ratings label. The voltage and current rating of the power cable should be greater than the ratings marked on the label.
For DC-input power supply modules, you must obtain the required cables; they are not shipped with the power supply module. Ensure that cable lengths, wire gauges, and lug sizes meet the chassis requirements, site-specific installation requirements, as well your local electric codes. See the Required Tools and Equipment section for further guidance.
· To help prevent electrical shock, plug all the power cables into properly grounded electrical outlets. These power cables are equipped with three-prong plugs to ensure proper grounding. Do not use adapter plugs or remove the grounding prong from a power cable.
· Observe power strip ratings. Make sure that the total current rating of all products that are plugged into the power strip does not exceed 80 percent of the power strip rating.
· Do not modify power cables or plugs yourself. Consult with a licensed electrician or your power company for site modifications. Always follow your local and national wiring codes.
Preventing ESD Damage
ESD damage might occur when modules or other FRUs are improperly handled, resulting in intermittent or complete failure of the modules or FRUs. Modules consist of printed circuit boards that are fixed in metal carriers. EMI shielding and connectors are integral components of a carrier. Although the metal carrier helps to protect the board from ESD, always use an ESD-grounding strap when handling modules. To prevent ESD damage, follow these guidelines:
· Always use an ESD wrist or ankle strap and ensure that it makes good skin contact.
· Connect the equipment end of the strap to an unfinished chassis surface.
· When installing a component, use an available ejector lever or captive installation screws to properly seat the bus connectors in the backplane or midplane. These devices prevent accidental removal, provide proper grounding for the system, and help to ensure that bus connectors are properly seated.
· When removing a component, use an available ejector lever or captive installation screws to release the bus connectors from the backplane or midplane.
· Handle carriers by available handles or edges only; avoid touching the printed circuit boards or connectors.
· Place a removed component board-side-up on an antistatic surface or in a static-shielding container. If you plan to return the component to the factory, immediately place it in a static-shielding container.
· Avoid contact between the printed circuit boards and clothing. The wrist strap only protects components from ESD voltages on the body; ESD voltages on clothing can still cause damage.
· Never attempt to remove the printed circuit board from the metal carrier.

Power Requirements
Preparing for Installation
Power Requirements
Power supply modules installed on a switch chassis can be all AC input, all DC input, or a mix of both. When preparing your site for switch installation, adhere to these requirements:
· In systems that are configured with more than one power supply, connect each of the power supplies to a separate input power source. If you fail to do this, your system might be susceptible to total power failure due to a fault in the external wiring or a tripped circuit breaker.
· To prevent loss of input power, ensure that the total maximum load on each source circuit is within the current ratings of the wiring and breakers.
· In some systems, you may decide to use a UPS to protect against power failures at your site. When selecting a UPS, be aware that some models, which use ferroresonant technology, may become unstable when operating with the switch power supplies that use power factor correction. This may cause the output voltage waveform to the switch to become distorted, resulting in an undervoltage situation in the system.
Power Connection Guidelines for AC-Powered Systems
When connecting AC-input power supply modules to the site power source, observe the guidelines described here.
Warning This unit might have more than one power supply connection. All connections must be removed to de-energize the unit. Statement 1028
· Ensure that the AC-input power supply module has a detachable power cord. · Each chassis power supply should have a separate, dedicated branch circuit.
· North America · C9400-PWR-3200AC only--Power supply modules require a 20 A circuit. · C9400-PWR-2100AC only--Power supply modules require a 15 A circuit.
· International--Circuits should be sized according to local and national codes.
· If you are using a 208 or 240 VAC power source in North America, note that such lines are considered hot and the circuit must be protected by a two-pole circuit breaker.

Cisco Catalyst 9400 Series Switches Hardware Installation Guide 39
Power Connection Guidelines for DC-Powered Systems
Preparing for Installation
Warning When stranded wiring is required, use approved wiring terminations, such as closed-loop or spade-type with upturned lugs. These terminations should be the appropriate size for the wires and should clamp both the insulation and conductor. Statement 1002
Warning Before performing any of the following procedures, ensure that power is removed from the DC circuit. Statement 1003
Warning Hazardous voltage or energy may be present on DC power terminals. Always replace cover when terminals are not in service. Be sure uninsulated conductors are not accessible when cover is in place. Statement 1075
Warning When installing or replacing the unit, the ground connection must always be made first and disconnected last. Statement 1046
Warning A readily accessible two-poled disconnect device must be incorporated in the fixed wiring. Statement 1022
Warning This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available. Statement 1024
Warning Use copper conductors only. Statement 1025
Warning Connect the unit only to DC power source that complies with the Safety Extra-Low Voltage (SELV) requirements in IEC 60950 based safety standards. Statement 1033
· All power connection wiring should conform to the rules and regulations prescribed by the National Electrical Code (NEC), as well as local codes, if any.
· The DC return must remain isolated from the system frame and the chassis (DC-I). The color coding of the source DC power cable leads depends on the color coding of the site DC power source. Typically, green or green and yellow stripes indicate that the cable is a ground cable. Since there is no color code standard for source DC wiring, you must ensure that the power cables are connected to the DC-input power supply terminal block in the proper + and - polarity. In some cases, the source DC cable leads might have a positive (+) or a negative () label. This label is a relatively safe indication of polarity, but you must verify the polarity by measuring the voltage between
Cisco Catalyst 9400 Series Switches Hardware Installation Guide 40
Preparing for Installation
Power Connection Guidelines for DC-Powered Systems
the DC cable leads. When measuring, ensure that the positive lead and the negative lead always match the "+" and "-" labels on the DC-input power supply terminal block, respectively. · DC power cables must be terminated by cable lugs at the power supply end. · The circuit must be protected by a dedicated two-pole DC-rated circuit breaker.
Warning This product requires short-circuit (overcurrent) protection, to be provided as part of the building installation. Install only in accordance with national and local wiring regulations. Statement 1045
The circuit breaker is considered to be the disconnect device and must be easily accessible. For DC-input power supply modules with multiple inputs, each DC input must be protected by a dedicated DC-rated circuit breaker or a fuse. The circuit breaker or fuse should be sized according to the power supply input rating and local or national code requirements.
Warning This product relies on the building's installation for short-circuit (overcurrent) protection. Ensure that the protective device is rated not greater than these values for the U.S. and EU: · 20 A circuit breaker for an AC-input power supply module. · 50 A DC-rated circuit breaker for each input of a DC-input power supply module, for safety purposes - irrespective of whether the inputs are power from a single or separate DC sources.
Statement 1005
· If the DC inputs are powered from separate sources, the cables must be wired straight across to their respective sources and terminals. Crossed cables in a setup where the DC source has floating outputs means that no damage will occur, but the LEDs will not light up, and the module will not operate. Crossed cables in a setup with a positive ground or a negative ground power system constitute a severe safety hazard that includes causing electric shock and generating excessive EMI and RFI. The following illustrations show the correct installation with two separate sources of DC power and a single source of DC power:

Cabling Requirements
Note * In the illustration, the red and black cables do not interconnect. The two black cables are connected to the same negative output of the DC source; the two red cables are connected to the same positive output of the DC source.
Cabling Requirements
When running power and data cables together in overhead cable trays or subfloor cable trays, be aware of the following caution:
Caution
We strongly recommend that power cabling runs and other potential noise sources be located as far away as practical from LAN cabling that terminates on Cisco equipment. In situations where this type of long parallel cable runs exist and cannot be separated by at least 3.3 feet (1 meter), we recommend that you shield these potential noise sources. To avoid interference, the source should be shielded by housing it in a grounded metallic conduit.
For IEEE 802.3bt Type 4 installations, we recommend using Category 6a cables, rated at 75°C with conductors 23AWG or larger, in bundle sizes of 192 or less. If your installation does not use the recommended cable, following are the other options that are compliant to National Electrical Code (NEC):
· Other Category cables (like Category 5e, or Category 6 cables) rated at 75°C, with conductors 23AWG, in bundle sizes of 192 or less.
· Limited Power (-LP) cable with 0.6A
· Cables with conductors 23AWG, rated at 60°C, in bundle sizes of 61 or less
· Cables with conductors 24AWG, rated at 75°C, in bundle sizes of 91 or less
· Cables with conductors 24AWG, rated at 60°C, in bundle sizes of 37 or less
For a detailed analysis on the recommended cabling, refer Analysis of Cabling Requirements for IEEE 802.3bt Type 4 Devices.

Cisco Catalyst 9400 Series Switches Hardware Installation Guide 43
Rack-Mounting Guidelines
Preparing for Installation
Accordingly, you can install the chassis in 2-post or 4-post racks, but in a 4-post rack, the rear posts are not used for mounting.
Width and Depth Requirements Use a tape measure to verify the interior dimensions of the rack
· Measure the space between the inner edges of the left front and right front mounting posts. The chassis is 17.30 inches (43.942 cm) wide and must fit between the mounting posts.
· Measure the depth of the rack from the outside of the front mounting posts to the outside of the rear mounting strip. The chassis is 16.30 inches (41.40 cm) deep.
Height Requirements The rack must have sufficient clearance in terms of height, to insert the chassis. Chassis height is also measured in rack units (RU or just U) where 1 RU or 1 U equals 1.75 inches (44.45 mm). A typical server rack is 42 RU or 42 U in height. The chassis heights are as follows:
· The Catalyst 9404R Switch chassis height--10.5 inches (26.67 cms)--6 RU. · The Catalyst 9407R Switch chassis height--17.41 inches (44.22 cms)--10 RU. · The Catalyst 9410R Switch chassis height--22.61 inches (57.43 cms)--13 RU.
Other General Guidelines
Caution If the equipment rack is on wheels, ensure that the brakes are engaged and that the rack is stabilized.
Warning To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to ensure that the system remains stable. The following guidelines are provided to ensure your safety: · This unit should be mounted at the bottom of the rack if it is the only unit in the rack. · When mounting this unit in a partially filled rack, load the rack from the bottom to the top with the heaviest component at the bottom of the rack. · If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the unit in the rack.

Verifying the Switch Chassis Installation
Verifying the Switch Chassis Installation
To verify the switch chassis installation, perform these steps: Procedure
Step 1 Step 2 Step 3
Step 4
Verify that the ejector levers of each module are fully closed (parallel to the faceplate) to ensure that the supervisor and all the line cards are fully seated in the backplane connectors.
Check the captive installation screws of each module, and tighten any loose captive installation screws.
Verify that all empty module slots and power supply bays have blanks installed properly. The blanks optimize the air flow through the chassis and contain EMI.
Warning
Blank faceplates and cover panels serve three important functions-- They prevent exposure to hazardous voltages and currents inside the chassis; they contain EMI that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system until all cards, face plates, front covers, and rear covers are in place. Statement 1029
Turn on the power supply switches to power up the system. During the power-up sequence, the system performs a series of bootup diagnostic tests.
Note The switch is designed to boot up in less than 30 minutes, provided that the neighboring devices are in fully operational state.
What to do next In case of a problem with any of the hardware components, refer to the Troubleshooting, on page 133 section. Additional system diagnostic tests are also available. These tests allow you to perform a complete sanity check on the system prior to inserting the system into your network and to monitor the health of the system while the system is running.
Tip When prestaging systems in a nonproduction environment, we recommend that you run all the diagnostic tests, including the disruptive tests, to prescreen the systems for failures, if any.

Removing and Installing a Fan Tray
Online Insertion and Removal While the fan tray is designed to be removed and installed while the system is operating (powered on) and without presenting an electrical hazard or damage to the system, there is a time constraint when you remove and replace the fan tray in a system that is powered on.
Caution If the service mode is not enabled, the system can safely run without a fan tray only for two minutes, until critical temperature threshold is exceeded. Watch for any alarms triggered in software. After the critical temperature threshold is exceeded, without sufficient cooling, the system shuts down if the alarm is not cleared.
When the fan tray is removed and replaced in a non operating system, there is no time constraint.
Following the Correct Removal and Replacement Procedure When you order the fan tray or a spare, the entire fan tray assembly is shipped. The fan tray assembly consists of the fan tray and an adapter that is attached to the fan tray. You can remove and replace the fan tray from the front or the rear. When removed from the front of the chassis, only the fan tray is removed. When removed from the rear, the entire fan tray assembly (including the adapter) is removed. Accordingly, you must detach the adapter from the spare fan tray assembly when installing or replacing the fan tray from the front; you must install the entire fan tray assembly when installing the spare from the rear. Removal and replacement from the front is suited to situations where access to the rear of the system is restricted. For instance, where the installation is in a closet. Removal and replacement from the rear is suited to situations where input and output cables are routed across the front panel, limiting access to the front panel of the fan tray. Follow the corresponding removal and replacement procedures.

Enabling the Service Mode Before Removing a Fan Tray
Removing and Replacing FRUs
Enabling the Service Mode Before Removing a Fan Tray
Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030
Warning No user-serviceable parts inside. Do not open. Statement 1073
Enabling the service mode is a precautionary step that we recommend you complete, before you remove a fan tray from the chassis. In the service mode, the system pushes the fans to operate at full speed for 10 minutes, allowing the system to cool down sufficiently and sustain temperatures for the duration of servicing. The system automatically turns off (self-terminates) the service mode after 10 minutes.
Important Proceed with removing and replacing the fan tray immediately after the service mode self-terminates.
· If the service mode is not enabled before servicing, only two minutes of fan-less operation can be safely assured in a normal environment.
· If the service mode is enabled prior to servicing, four minutes of fan-less operation can be assured for all normal operating conditions, at full traffic load, in any configuration.
In a system that is operational, enabling the service mode applies to removal or replacement procedures from the front and the rear. You do not have to enable this mode if you are removing and replacing the fan tray in a system that is not powered on. The service mode is also not required if the fan tray is being replaced for having two or more bad individual fans, because the fan tray will already be running at full speed. To enable the service mode, enter the test platform hardware chassis fantray service-mode on command in the privileged EXEC mode. For example:
Device# test platform hardware chassis fantray service-mode on fantray service mode on
To turn off the service mode before the system-allotted 10-minute duration, enter the test platform hardware chassis fantray service-mode off command in the privileged EXEC mode.

Warning
In the course of its operation the system may require more than one power supply installed and supplying power. Should it become necessary to remove an active power supply unit from the system, consult the user manual for proper system administration of available power. In order to safely de-energize the power supply unit, the input power should first be turned off by activating the rocker input power switch switch into the OFF state and the power cable physically disconnected from the unit. The unit must then be removed from the slot and stowed safely away in a proper antistatic bag. Care must be taken not to touch any of the exposed pins from the backplane connector. When a replacement power supply unit is to be installed, its rocker switch must always be in the OFF state and no input power cable be installed prior to inserting it into the slot. After the unit is seated, the input power cable may then be installed and fastened securely before activating the input power into the ON state with the rocker input power switch prior to energizing the unit. Statement 1028
What to do next Set the power supply aside and proceed with installing the new or replacement power supply module. Install blank covers in all power supply bays that are to remain empty (C9400-PWR-BLANK). For information about installing blank covers, see Removing and Installing a Power Supply Blank, on page 129

Removing a DC-Input Power Supply Module
When removing a DC-input power supply module, you will need access to the terminal block of the module to disconnect the DC-input wires. If the front panel of the chassis has limited access because of other interfering cables, consider removing the module from the chassis before disconnecting the DC-input wires. If you do have clear access to the terminal block, you can disconnect the DC-input wires and then remove the module from the chassis. In either case (whether you have access to the front panel or not), you must begin by completing all the steps described in Powering Down the DC-Input Power Supply. Proceed with the next task depending on your setup. The procedures to disconnect DC-input wires and to remove the module from the chassis have been described in Disconnecting the DC-Input Wires, on page 116 and Removing a DC-Input Power Supply Module from the Chassis, on page 119.

About this Section
This chapter describes how to perform basic troubleshooting on Cisco Catalyst 9400 Series Switches. Problems with the initial startup are often caused by a line card that has become dislodged from the backplane or a power cord that is disconnected from the power supply. Although temperature conditions above the maximum acceptable level rarely occur at initial startup, some environmental monitoring functions are included in this chapter because they also monitor power supply output voltages.
Note This chapter covers only the chassis component hardware aspects of troubleshooting. For software configuration issues, refer to the software configuration guide
System Boot Verification
When the initial system boot is complete, verify the following: · That the system software boots successfully
Cisco Catalyst 9400 Series Switches Hardware Installation Guide 133
Using LEDs to Identify Startup Problems
Troubleshooting
Hook up a terminal and view the startup banner. Use an RJ-45-to-RJ-45 rollover cable to connect the console port to a PC with terminal emulation software set for 9600 baud, 8 data bits, no parity, and 1 stop bit. Watch for any system messages after startup.
· That the power supplies are supplying power to the system
The power supply's LED should be green. Use the show environment Cisco IOS command to view power supply activity.
· That the system fan assembly is operating
Listen for fan activity. The Fan tray LED should be green during operation. Use the show environment Cisco IOS command to view fan tray activity.
· That the supervisor and all line cards are installed properly in their slots, and that each initialized without problems.
If all of these conditions are met and the hardware installation is complete, refer to the software configuration guide and command reference publications for your switch so that you can troubleshoot the software.
If any of these conditions is not met, use the procedures in this chapter to isolate and, if possible, resolve the problem.
Using LEDs to Identify Startup Problems
The key to success when troubleshooting the system is to isolate the problem to a specific system component. Your first step is to compare what the system is doing with what it should be doing. All system states in the startup sequence are indicated by LEDs. By checking the LEDs, you can determine when and where the system failed in the startup sequence. If you have problems after the switch is on, refer to the following subsystem troubleshooting information and the configuration procedures in the software configuration guide for your switch.
After you connect the power cords to your switch, follow these steps to determine whether your system is operating properly:
Procedure
Step 1
Step 2 Step 3
Check the power supply LEDs: The INPUT LED should turn green when power is applied to the supply. The LED should remain on during normal system operation. If the INPUT LED does not light, or if the LED labeled FAIL lights, see the "Troubleshooting the Power Supply" section. Note If a power supply is installed and not connected to a power source, power supply LEDs are not lit.
Listen for the system fan assembly. The system fan assembly should be operating whenever system power is on. If you do not hear it when the switch is on, see the "Troubleshooting the Fan Assembly" section. Check that the LEDs on the supervisor module light as follows:
· The STATUS LED flashes amber once and stays amber during diagnostic boot tests. · It turns green when the module is operational (online).
Cisco Catalyst 9400 Series Switches Hardware Installation Guide 134
Troubleshooting
System Messages
· If the system software is unable to start up, this LED turns red.
If the LED is red, connect a console to the management port and use the show environment command to check for possible problems.
· The MANAGEMENT LED turns green when the module is operational (online) and a link is established with another network device. If no signal is detected, the LED turns off.
· If there is a problem with the supervisor module, try reseating the supervisor module in the chassis and restarting the switch. For more troubleshooting information, see the "Troubleshooting Supervisor Modules" section.
· Verify that the STATUS LEDs on each line card is green when the supervisor module completes initialization.
This LED indicates that the supervisor module and line cards are receiving power, have been recognized by the supervisor module, and contain a valid Flash code version. However, this LED does not indicate the state of the individual interfaces on the line cards. If a STATUS LED is red, try reseating the line card or supervisor module and restarting the switch. For more information, see the "Troubleshooting Line Cards" section. If you determine that the line card is not operating, contact Cisco TAC as described in the "Some Problems and Solutions" section. · If the boot information and system banner are not displayed, verify that the terminal is set for 9600 baud, 8 data bits, no parity, and 1 stop bit and connected properly to the console port.
System Messages
System messages appear on the console if you have enabled console logging or appear in the syslog if you have enabled syslog. Many messages are for informational purposes only and do not indicate an error condition. Enter the show logging command to display the log messages. To better understand a specific system message, refer to the system message guide for your software release.
Troubleshooting with Software
Many problems can be identified with CLI commands, and following sections will mention them as appropriate. Certain problems can be due to not having the right software to support your hardware.

The INPUT should be solid green for normal operation. If the INPUT LED is off, take the following steps: a) Ensure that the power supply is flush with the back of the chassis by gently inserting it all the way in until
it stops. You should feel the retaining metal latch, on its right side, click into place. The unit should not be removable without depressing this latch towards it.
Note You should be unable to remove the power supply from the system when the power cord is fully inserted and installed with the cord retainer.
b) Unplug the power cord by loosening the cord retainer and physically reinstalling the power supply, plug in the power cord and tighten the cord retainer around it.
c) If the INPUT LED remains off, there may be a problem with the AC source or the power cable connection. Also check the circuit breaker of the AC source. Connect the power cord to another power source if one is available. Verify that the source power is within the acceptable specifications of the power supply.
d) If the LED remains off after you connect the power supply to a new power source, replace the power cord. e) If the LED still fails to light when the switch is connected to a different power source with a new power
cord, the power supply is probably faulty. You may need to replace the power supply.
The OUTPUT LED should be solid green for normal operation. Blinking green indicates that the unit is asleep in standby mode. If the FAIL LED is red, take the following steps: a) Remove the power supply from the bay and visually inspect the rear of the power supply module connector.
If there is no damage, try installing it in another empty power supply bay, if available. Do not touch the back of the power supply module during this inspection. If the OUTPUT LED turns green, the problem

Troubleshooting a DC-Input Power Supply
To help isolate a power subsystem problem, follow these steps:
Procedure
Step 1
The INPUT LED should be solid green for normal operation. If the INPUT LED is off, perform the following steps: a) Check the DC source.
1. Check that the circuit breaker of the DC source is ON.
2. Connect the cables to another power source if one is available. Verify that the source power is within the acceptable specifications of the power supply.
3. Check that you have connected both the DC inputs to a suitable DC source. The power supply module is not designed to function with just one DC input.
4. If you are using a single source, check that it is capable of providing 3500 W of DC-input power. If it is two different sources, check that each source is able to provide 1750 W of DC-input power.
5. Ensure that the DC source is capable of providing a minimum of -40 V to the input terminals of the DC power supply module. .
b) Check the DC-input cable connections 1. Check that the lugs are fastened properly and torqued to between 2.0 and 2.8 Nm.
2. Check that the polarity of the DC-input cables is not reversed. For more information, see Power Connection Guidelines for DC-Powered Systems, on page 39
3. If you are using a separate source for each DC input, check that you have not crossed the cables (reversed positive or negative inputs).
Step 2
Note If the INPUT LED still fails to light, the power supply module is probably faulty. You may have to replace it.
The OUTPUT LED should be solid green for normal operation. Blinking green indicates that the unit is asleep in standby mode. If the OUTPUT LED is off, perform the following steps:

Restoring the Default Mode of the Power Button for a DC Power Supply Module
Troubleshooting
Step 3
a) Check if you have pressed the power button for two seconds to turn on the module. b) Check if the INPUT LED is on; if it is not, follow the steps to troubleshoot the INPUT LED first (Step
1). c) Check if the release latch has been pushed in to lock it.
The FAIL LED should be OFF for normal operation. If the FAIL LED is red, perform the following steps: a) Check the power button.
If the power button on the front panel of the module is turned off after DC input is applied, the FAIL LED will be solid red until you press the power button for two seconds to turn it on again.
b) Inspect the module.
Remove the power supply module from the bay and visually inspect the rear of the power supply module connector. If there is no damage, try installing it in another empty power supply bay, if available. Do not touch the back of the power supply module during this inspection. If the OUTPUT LED turns green, the problem may lie with the first power supply bay and not the power supply module. Call Cisco Technical Assistance Center (Cisco Support) for further instructions.
c) Test with another spare.
If a second power supply module is available, install it in the second power supply bay.
1. Check that the INPUT LED is on for the second power supply, and that the FAIL LED is off.
2. If the INPUT LEDs for this second power supply is not on, repeat the procedure to troubleshoot INPUT LED of the second power supply (Step 1).
3. If the FAIL LED for this second power supply is on, repeat steps to troubleshoot the FAIL LED (Step 3).
Step 4
Contact Cisco Technical Assistance Center.
If you are unable to resolve the problem, or if you determine that either a power supply or backplane connector is faulty, contact Call Cisco Technical Assistance Center (Cisco Support) for instructions.
Restoring the Default Mode of the Power Button for a DC Power Supply Module
If you are unsure of whether the power button of a DC-input power supply module is in the auto-on mode or the protected mode, you can restore the default mode (auto-on). Begin by checking the following: 1. The number of power supply modules currently configured 2. If the 3.3-VDC standby output is active (applied)

Troubleshooting the Fan Tray Assembly
Note All fans must be operating or a failure will occur.
Environmental problems may initially appear to be problems with the fan tray. To help isolate a fan assembly problem, follow these steps:
Cisco Catalyst 9400 Series Switches Hardware Installation Guide 139
Troubleshooting the Fan Tray Assembly
Troubleshooting
Procedure
Step 1
Step 2 Step 3 Step 4 Step 5 Step 6 Step 7
Check the STATUS LED on the fan tray · If the LED is off and the rest of the system is functioning, the fan tray is not getting power or is not seated correctly on the backplane.
· If the LED is green, the fans are operating normally. There may be conditions impairing fan performance, but they are minimal in impact.
· If the LED is amber, one fan has failed.
· If the LED is red, two or more fans have failed. If LED remains red for more than one minute, fans are pushed to operate at full speed, causing loud noise levels.
· If the LED is off and the fans are not running at all, make sure to insert it all the way and to tighten the screws. If you have serviced the fan from the front, ensure that the captive installation screws in the rear are also sufficiently tight. If you have serviced the fan from the rear, ensure that the captive installation screws in the front are also sufficiently tight. Fans may take a few seconds to start ramping up in speed.
Connect a terminal and determine the fan tray status shown by the show environment status privileged EXEC command command. The status and sensor columns read good--the STATUS is green The status and sensor columns read marginal--the STATUS is amber, one fan has failed. The status and sensor columns read bad--the STATUS is red, two or more fans have failed.
Determine whether the airflow is restricted; verify that the minimum rack clearance requirements are met. See Air Flow, on page 28. Determine whether the power supply is functioning properly. Verify that the fan tray assembly is properly seated, by loosening the captive installation screws, removing the fan assembly, and reinstalling it. Note There is a time constraint when you remove and replace the fan tray in a system that is powered on.
The system can safely run without a fan tray only for 2 minutes. There is no time constraint in a system that is not powered on.
Restart the system. Verify that all fans are operating. You should hear the fans at system start.
What to do next
If the system is still detecting a fan assembly failure, check for details using the Cisco IOS commands, save the logs, and contact the Cisco TAC for assistance.

Troubleshooting High Temperature Alarms
A dirty air filter may cause overheating of the switch. Multiple board temperature sensors trigger alarm in case of overheating caused by dirty filter. Inspect the air filter if the high temperature alarm goes off. Cleaning and Replacing Air Filters The air filter removes dust from the room air drawn into the switch by the cooling fans. Once a month (or more often in industry environments), you should examine the air filter. If the filter appears dirty, you can either vacuum or replace it. If the filter appears worn or torn, dispose of it in a responsible manner and install a replacement air filter.
Note We recommend that you change the air filter every three months. However, examine the air filter once a month (or more often in dusty environments) and replace it if it appears to be excessively dirty or damaged. To comply with Telecordia GR-63-Core standard air filter requirements for NEBS deployments, the air filter must be replaced, not cleaned

Troubleshooting Supervisor Modules
This section only addresses problems with hardware. Problems with features or configuration are not covered here. Refer for your software configuration guide and release notes for information on configuring features or identifying known problems.
Supervisor Module LEDs
· Check the LEDs on your supervisor and compare them to the described LED behaviors. See Cisco Catalyst 9400 Series Supervisor Module LEDs, on page 168
· The Supervisor Module STATUS LED turns either amber or red under the following conditions: · Power supply failure (not the same as removal of power supply) · Power supply fan failure · Removal or failure of fan tray · Mismatched power supplies in the chassis
Standby Supervisor Engine Problems
· Switch# show module If the standby supervisor module is not online or status indicates "other" or "faulty" in the output of the show module command or an amber status LED, create a console connection to the standby supervisor and check if it is in ROMMON mode or in continuous reboot. If the standby supervisor is in either of these two states, refer to the System Management > Troubleshooting the Software Configuration section of the Software Configuration Guide
· Make sure that the supervisor module properly seats in the backplane connector and that you have completely screwed down the captive screws for the supervisor module.
· Switch# redundancy reload peer
Cisco Catalyst 9400 Series Switches Hardware Installation Guide 142
Troubleshooting
Switch Self Reset
In order to determine whether the standby supervisor module is faulty, enter the redundancy reload peer command from the active supervisor and through the console to the standby supervisor. Observe the bootup sequence in order to identify any hardware failures. Currently, the active supervisor module cannot access the power-on diagnostics results of the standby supervisor module.
· Make sure that these configurations are synchronized between the active and redundant supervisor modules: · Startup configuration
· Boot variable
· Configuration register
· Calendar
· VLAN database
If a software upgrade is performed on both the active and standby supervisor module, verify that both supervisor modules are running the same new software image. If the software images are not the same, upgrade the software image. Use the procedure in the software configuration guide for your release. If the standby supervisor still does not come on line, create a service request with Cisco Technical Support. Use the log of the switch output that you collected from the previous troubleshooting steps.
Switch Self Reset
If the switch has reset or rebooted on its own, verify that the power source for the switch did not fail. If you use an uninterruptable power supply (UPS), make sure that the UPS does not have any problems. The switch might have had a software crash. Enter the more crashinfo:data command to display the crash information including date and time of the last time that the switch crashed. To display the standby supervisor engine crash data, enter the more slavecrashinfo:data command. Crash data is not present if the switch has not crashed. If the output indicates a software crash at the time that you suspect that the switch rebooted, the problem can be something other than a hardware failure.

Cannot Connect to a Switch Through the Console Port
Make sure you are using the correct type of cable and that the cable pinouts are correct for your supervisor module Make sure the terminal configuration matches the switch console port configuration--default console port settings are 9600 baud, 8 data bits, no parity, 1 stop bit. To access the switch through the console port, the following must match
· The BAUD environment variable in the ROMMON
Cisco Catalyst 9400 Series Switches Hardware Installation Guide 143
Cannot Connect to a Switch Through the Console Port
Troubleshooting
· Console port speed · Start-up configuration
Note The factory default for the the BAUD environment variable is an explicit setting: BAUD variable=9600. This variable also defaults to 9600 (implicit setting) when a variable is not set explicitly.
During initial switch configuration, proceed as follows:
1. Ensure that the terminal configuration matches the switch console port speed configuration. The following example uses a Cisco switch as the console, and the console port number is 8. Enter the appropriate console port number when you configure the console port speed.
Switch# configure terminal Enter configuration commands, one per line. Switch(config)#line 8 Switch(config-line)# speed 9600
End with CNTL/Z.
2. Access ROMMON prompt and verify the BAUD setting on the switch--Connect the console to system and while system is booting, after you see the the prompt, press CTRL+C to stop booting and access ROMMON prompt. In the example, the factory default setting is retained.
rommon 1> set BAUD=9600 <output truncated>
If you want to change this setting, you can do so now
rommon 2> set BAUD <enter new speed>
If you enter a new speed, you must redo step 1 because you will lose ROMMON access immediately after setting a new speed.
3. Boot the image.
rommon 4> boot
During bootup, the BAUD rommon setting on the active supervisor is automatically synced to the standby.
4. Save the running configuration:
Switch# copy system:running-config nvram:startup-config
When the BAUD rommon variable is set in ROMMON mode, this value is extracted for the line console in the running configuration, when the system reloads. However, when the system parses the startup-configuration, the startup-configuration speed supercedes the value retrieved from BAUD. This step gets the BAUD and startup-config line console speed to match. A mismatch can cause loss of access to the console port.
Note Any time you manually change the BAUD speed in the ROMMON (explicitly set a new speed), you may lose console port access after a reload, or when switch boots, depending on what the BAUD speed and the console port speed is in the startup-configuration. The console port speed must be changed to match the new speed setting. After console access is restored, save the configuration to synchronize BAUD ROMMON speed, startup-configuration, and line console speed. Enter the show bootvar command to verify the new BAUD variable setting.
Cisco Catalyst 9400 Series Switches Hardware Installation Guide 144
Troubleshooting
Cannot Connect to a Switch Through the Console Port
Possible BAUD Mismatch--Scenario 1
Description--When you started off, the BAUD variable, start-up configuration and console port speed were all set to 115200. After this, if you unset the BAUD parameter at some point...
1. This is an implicit change in the BAUD variable to 9600 and not an explicit setting in the ROMMON. Further, the current console port session speed is still set to 115200 and you still have access.
2. Boot the image--Cisco IOS boots the image normally. The line console speed is initially retrieved from BAUD (9600), but Cisco IOS parses the startup-configuration, and the speed is changed to 115200. This matches the current console port speed.
3. Reload or power cycle the switch--Setup goes back to ROMMON mode and console access is lost because the default BAUD speed of 9600 is effective and mismatched with the console port speed. Set console port speed to 9600 to restore access.
4. Boot the image--Console port access is lost because the line console speed is initially retrieved from BAUD (9600), Cisco IOS parses the startup-configuration, where the speed is set to 115200 and not in sync with console port 9600 speed, and console port access is lost. Access is restored once console port speed is set to 115200.
5. Reload or power cycle the switch--Setup goes back to ROMMON mode, but console access is lost again due to mismatched BAUD of 9600.
In the above scenario, note the difference between an unset BAUD in step no.1 (where the implicit speed is 9600) and a set BAUD=9600 command (where the speed is explicitly set using the "set" command in ROMMON). You are able to access the console until step no.4 because the BAUD has an unset, implicit speed of 9600, but the speed was not actually changed from 115200. Once you reloaded or power cycled in step no.5, the speed was set to 9600.
Solution 1--If you save running configuration to start-up configuration (copy system:running-config nvram:startup-config) at step no. 2 then BAUD and the startup-configuration are synchronized with speeds at 115200, and subsequent reloads will not interrupt access.
Solution 2--(Instead of performing the above steps) Configure the line console speed to 9600, change the console port speed to 9600, and then save running configuration to start-up configuration, then BAUD in ROMMON and startup-configuration will be synchronized with speeds at 9600.
Possible BAUD Mismatch--Scenario 2
Description--When you started off, the BAUD environment variable, startup-configuration speed and console port speed were all 9600. (The BAUD and startup configuration speeds have not been set explicitly). After this, at some point you explicitly set the BAUD variable to 115200...
1. You lose console access immediately. Set the console port speed to 115200 to restore access.
2. Boot the image--Line console speed is initially retrieved from BAUD (115200). While booting, the system parses the startup-configuration, but even though the configured speed is 9600, this is the value that the system defaults to, and the "speed 9600" line is not actually present in startup-configuration. Since the speed configuration is not present, it is not explicitly parsed and applied, so the speed retrieved from BAUD previously (115200) is used.
In this state, the line console speed is set to 115200, matching BAUD, while the startup-configuration has line console speed as default (9600). The system is useable since the speed was not changed to 9600, even with the BAUD and startup-configuration mismatch. If you save running configuration to start-up configuration, then BAUD and startup-config will be in sync with speeds explicitly set to 115200.

Boot Problems
Troubleshooting
Boot Problems
The supervisor module operates in a continuous loop by default if you have not set the boot variable MANUAL_BOOT in ROMMON mode. To boot manually, set MANUAL_BOOT=yes; to auto-boot, set MANUAL_BOOT=no. The supervisor module goes into ROMMON mode or fails to boot when the system image is either corrupt or absent. The supervisor module has an onboard system Flash memory (bootflash), which can easily hold multiple system images. Therefore, have a backup image. In addition to the bootflash, the supervisor module supports compact Flash in the usbflash0: device. The supervisor also provides for transfer via TFTP of the image from ROMMON mode, which enables faster recovery of absent or corrupt images. In addition to the above mentioned storage devices, you can install a hard disk, which is displayed as disk0:. We recommend that you use this for general purpose file storage, similar to usbflash0:, but not to store system images.

Table 15: 2100-W AC-Input Power Supply Specifications
Specification AC-input type
AC-input voltage AC-input current AC-input frequency Branch circuit requirement
Description
Wide-ranging input with power factor correction. Note Power factor correction is a standard feature on AC-input power supplies.
Power factor correction reduces the reactive component in the source AC current, allowing higher power factors (0.90 minimum at loads equal to or greater than 20 percent of maximum loads, and 0.95 minimum at 2100W maximum loads, at 115/230 VAC nominal AC input voltages) and lower harmonic current components.
Low-line (115 VAC nominal)--85 VAC (min) to 132 VAC (max) High-line (230 VAC nominal)--180 VAC (min) to 264 VAC (max)
11.44 A at 100 VAC (950 W output) 11.44 A at 200 VAC (2112 W output)
50/60Hz nominal (47 to 63Hz full range)
Each chassis power supply should have its own dedicated, fused-branch circuit: · North America--15 A.
· International--Circuits sized to local and national codes.
· All AC power supply inputs are fully isolated. · Source AC can be out of phase between multiple power supplies in the same chassis, which means that PS1 can be operating from phase A and PS2 can be operating from phase B.
· For high-line operation, the power supply operates with the line conductor wired to an source AC phase, and the Neutral conductor wired either to a Neutral, single-phase power system, or to another source AC phase as long as the net input voltage is in the range of 180 to 264 VAC.

Initial Configuration for the Switch
· Options for Initial Configuration, on page 173 · Configuring the Switch Using the Web User Interface, on page 173 · Configuring the Switch Using the CLI, on page 174 · Configuring the Switch in the ROMMON Mode, on page 179 · Installing and Uninstalling the USB Driver, on page 179
Options for Initial Configuration
After you complete the hardware installation, you need to setup the switch with configuration required to enable traffic to pass through the network. On your first day with your new device, you can perform a number of tasks to ensure that your device is online, reachable and easily configured. When the supervisor module is shipped, the factory default setting for MANUAL_BOOT is no. This means that when you first power on the device, it will always boot automatically. So these are the first options available to you for initial configuration:
· Configuring the Switch Using the Web User Interface · Configuring the Switch Using the CLI · Configuring the Switch in the ROMMON Mode
This option requires you to interrupt autoboot (factory default) and enter the ROMMON prompt to enter the required settings. Use this option if you want to boot the system by using an image that is located on a TFTP server.
Configuring the Switch Using the Web User Interface
For instructions on setting up the switch using the WebUI, refer to the required version of the software configuration guide. In the guide, go to Configuring the Switch Using the Web User Interface.

Starting the Terminal-Emulation Software
To start the terminal emulation software, follow these steps:
Before you begin The terminal-emulation software--frequently a PC application such as Hyperterminal or ProcommPlus--makes communication between the switch and your PC or terminal possible.
Procedure
Step 1 Step 2 Step 3
Start the terminal-emulation program if you are using a PC or terminal. Start a terminal-emulation session. Configure the baud rate and character format of the PC or terminal to match these console port default characteristics:
· 9600 baud
· 8 data bits
· No flow control
· 1 stop bit
· No parity
What to do next Connect to a power source.
Connecting to a Power Source
To connect to a power source, follow these steps: Procedure
Step 1 Step 2
Connect one end of the supplied country-specific AC power cord to the power connector on the switch. Plug the other end into a grounded 100 to 240 VAC, 5060 Hz AC outlet. The switch powers on.

Analysis of Cabling Requirements for IEEE 802.3bt Type 4 Devices
The National Electrical Code (NEC) in its 2017 edition describes the restrictions on Power over Ethernet (PoE) systems. The restrictions are based on the per-conductor current and are targeted to minimize the thermal rise that may occur in large bundles of cable delivering Power over Ethernet.
Note The NEC defines a cable bundle as a group of cables that are tied together or in contact with one another in a closely packed configuration for at least 1.0m (40 in).
A standard Category cable used in Ethernet systems consists of eight conductors. IEEE 802.3af and 802.3at systems use only four of these conductors to carry current. Cisco UPOE and IEEE 802.3bt systems use all eight conductors to carry current. The following table lists the maximum current allowed under each standard and the associated per-cable and per-conductor current.
Table 27: Maximum Current prescribed for various Standards
Standard 802.3af 802.3at Cisco UPOE 802.3bt
Cable Current 350mA 600mA 1200mA 1732mA
Conductor Current 175mA 300mA 300mA 433mA
Analysis of a cabling system for compliance to the NEC starts with section 840.160:
Installation of the listed 4-pair communication cables for a communication circuit or installation where 4-pair communication cables are substituted for Class 2 and Class 3 cables in accordance with 725.154(A) shall comply with 725.144. Exception: Installing communications cables in compliance with 725.144 shall not be required for listed 4-pair communications cables where the rated current of the power source does not exceed 0.3 amperes in any conductor 24 AWG or larger.
This, in effect states that 802.3af, 802.3at, and Cisco UPOE systems do not require any further consideration when the conductors are 24AWG or larger. Also, TIA-568 compliant horizontal cables require a minimum
Cisco Catalyst 9400 Series Switches Hardware Installation Guide 183
Analysis of Cabling Requirements for IEEE 802.3bt Type 4 Devices
Analysis of Cabling Requirements for IEEE 802.3bt Type 4 Devices
of 24AWG conductors. Hence any IEEE standard compliant PoE system that supplies 60W or less does not need additional cable consideration.
IEEE 802.3bt Type 4 systems (Class 7 and Class 8, 75W and 90W) do not qualify for the 0.3A exemption. Therefore, the analysis for compliance to NEC moves to section 725.144:
Where Types CL3P, CL2P, CL3R, CL2R, CL3, or CL2 transmit power and data, the rated current per conductor shall not exceed the ampacities in Table 725.144 at an ambient temperature of 30°C (86°F). For ambient temperatures above 30°C (86°F), the correction factors of 310.15(B) shall apply. Exception: Compliance with 725.144 shall not be required for installations where conductors are 24 AWG or larger and the rated current of the power source does not exceed 0.3 amperes. Types CL3P-LP, CL2P-LP, CL3R-LP, CL2R-LP, CL3-LP, or CL2-LP shall be permitted to supply power to equipment from a power source with a rated current per conductor up to the marked ampere limit located immediately following the suffix "-LP" and shall be permitted to transmit data to the equipment.
The following table is derived from Table 725.144, adjusted for 45°C ambient temperature using 310.15(B).
The values in green cells are accepted values for IEEE Type 4 PoE systems.
Figure 68: NEC 2020 Table 725.144 adjusted for 45°C ambient temperature
Analysis of the NEC 2020 Table 725.144, adjusted for 45°C, and the requirements of section 725.144 results in Cisco's recommendation to use Category 6a cables rated at 75°C, with 23AWG conductors, in bundles sizes of 192 or less.
