4. Setup Instructions

The Cisco SG110-16HP is an unmanaged switch designed for simple plug-and-play installation. No software configuration is required.

4.1 Placement

• Place the switch on a flat, stable surface or mount it using the provided hardware.
• Ensure adequate ventilation around the switch to prevent overheating.
• Keep the switch away from strong electromagnetic fields, vibration, dust, and moisture.

4.2 Power Connection

1. Connect the provided power cord to the power input on the back of the switch.
2. Plug the other end of the power cord into a grounded electrical outlet.
3. The Power (PWR) LED on the front panel will illuminate when the switch receives power.

4.3 Network Connections

1. Connect your network devices (computers, servers, network printers, etc.) to any of the 16 Gigabit Ethernet ports using standard Ethernet cables.
2. For devices requiring Power over Ethernet (PoE), connect them to ports 1 through 8. These ports automatically detect and provide power to compatible PoE devices.
3. The Link/Act LED for each connected port will illuminate when a valid network connection is established and will blink to indicate network activity.
4. The Max PoE LED will illuminate if the total power draw from PoE devices approaches the maximum budget (64W).

5. Operating the Switch

The SG110-16HP is an unmanaged switch, meaning it operates automatically without user configuration.

5.1 Basic Functionality

• Gigabit Speed: All 16 ports support 10/100/1000 Mbps (Gigabit Ethernet) for high-speed data transfer.
• Auto-negotiation: Each port automatically detects the network speed and duplex mode of the connected device and adjusts accordingly.
• Auto MDI/MDIX: Eliminates the need for crossover cables; simply use straight-through cables for all connections.

5.2 Power over Ethernet (PoE)

• Ports 1-8 are PoE-enabled, providing power to compatible devices such as IP phones, wireless access points, and IP cameras.
• The total power budget for PoE is 64W. Ensure the combined power draw of all connected PoE devices does not exceed this limit.
• The switch automatically detects if a connected device is PoE-compatible and supplies power.

6. Maintenance

The Cisco SG110-16HP switch is designed for minimal maintenance.

• Cleaning: Periodically clean the exterior of the switch with a soft, dry cloth. Do not use liquid or aerosol cleaners.
• Ventilation: Ensure that the ventilation openings are not blocked to maintain proper airflow and prevent overheating.
• Firmware Updates: As an unmanaged switch, firmware updates are typically not required or user-installable.
• Energy Efficiency: The switch optimizes power usage in compliance with IEEE802.3az Energy Efficient Ethernet, reducing operational costs.

7. Troubleshooting

If you encounter issues with your Cisco SG110-16HP switch, consider the following troubleshooting steps:

• No Power:
  • Verify the power cord is securely connected to both the switch and a working electrical outlet.
  • Check if the power outlet is functional by plugging in another device.
• No Link/Activity:
  • Ensure the Ethernet cable is securely connected to both the switch port and the network device.
  • Try a different Ethernet cable to rule out cable failure.
  • Connect the device to a different port on the switch.
  • Verify the connected device is powered on and functioning correctly.
• PoE Device Not Powering On:
  • Confirm the device is connected to one of the PoE-enabled ports (ports 1-8).
  • Check if the device is PoE-compatible (IEEE 802.3af/at standard).
  • Ensure the total power consumption of all PoE devices does not exceed the 64W budget. If the Max PoE LED is on, disconnect some PoE devices or use an external power source for some.
  • Try connecting the PoE device to a different PoE port.
• Slow Network Performance:
  • Check for excessive network traffic or bandwidth-intensive applications.
  • Ensure all connected devices are operating at Gigabit speeds (1000 Mbps) if expected.
  • The switch supports Quality of Service (QoS) to prioritize traffic, but as an unmanaged switch, this is automatic and not user-configurable.
