10/100BASE-T Ports
You can set the 10/100BASE-T ports on the switch to operate in any combination of half duplex, full duplex, or 10 or 100 Mb/s. You can set the ports for speed and duplex auto-negotiation. The default setting is auto-negotiate.
When set for auto-negotiation, the switch determines the speed and duplex settings of the attached device, and advertises its own capabilities. If the connected device also supports auto-negotiation, the switch negotiates the best connection (the fastest line speed that both devices support and full-duplex transmission if the attached device supports it), and configures itself accordingly. In all cases, the attached device must be within 328 feet (100 meters). The 10/100BASE-T ports use RJ-45 connectors with Ethernet pinouts. The maximum cable length is 328 feet (100 meters). The 100BASE-TX traffic requires Category 5, Category 5e, or Category 6 unshielded twisted pair (UTP) cable. The 10BASE-T traffic can use Category 3 or Category 4 UTP cable.
Note
On the GRWIC-D-ES-2S-8PC switch module, the first four 10/100 Fast Ethernet ports (FE0/1, FE0/2, FE0/3, FE0/4) are PoE+ ports.
PoE and PoE+ Ports
The first four 10/100 Fast Ethernet ports (FE0/1, FE0/2, FE0/3, FE0/4) on the GRWIC-D-ES-2S-8PC switch module are PoE+ ports.
Warning
Voltages that present a shock hazard may exist on Power over Ethernet (PoE) circuits if interconnections are made using uninsulated exposed metal contacts, conductors, or terminals. Avoid using such interconnection methods, unless the exposed metal parts are located within a restricted access location and users and service people who are authorized within the restricted access location are made aware of the hazard. A restricted access area can be accessed only through the use of a special tool, lock and key or other means of security. Statement 1072
These PoE+ ports provide:
- Support for IEEE 802.3af-compliant powered devices (up to 15.4 W PoE per port) and support for IEEE 802.3at-compliant powered devices (up to 30 W PoE+ per port).
- Support for prestandard Cisco powered devices.
- Configurable support for Cisco intelligent power management, including:
- enhanced power negotiation
- power reservation
- per-port power policing
On the GRWIC-D-ES-2S-8PC model (Copper model), the first four 10/100BASE-T ports (FE0/1, FE0/2, FE0/3, FE0/4) are PoE+ ports. A maximum of two PoE+ ports or four PoE ports can be supported at one time.
For information about configuring and monitoring PoE/PoE+ ports, see the “Interface Configuration” chapter of the Cisco Connected Grid Ethernet Switch Module Interface Card Software Configuration Guide on Cisco.com.
For information about port connections and port specifications, see the “Connecting Devices to the Switch Module” section on page 4-4 and the “Cable and Connectors” appendix.
Note
The output of the PoE+ circuit has been evaluated as a Limited Power Source (LPS) per IEC 60950-1.
10/100 Mb/s SFP Module Slots
The IEEE 802.3u 100 Mb/s SFP module slots provide full-duplex 100 Mb/s connectivity over multi-mode (MM) fiber cables or single-mode (SM) fiber cables. These ports use a SFP fiber-optic transceiver module that accepts a dual LC connector. Check the SFP specifications for the cable type and length.
100/1000 Mb/s SFP Module Slots
The IEEE 802.3u 1000 Mb/s SFP module slots provide full-duplex 100 or 1000 Mb/s connectivity over multi-mode (MM) fiber cables or single-mode (SM) fiber cables. These ports use a SFP fiber-optic transceiver module that accepts a dual LC connector. Check the SFP specifications for the cable type and length.
Dual-Purpose Gigabit Ethernet Ports
You can configure the dual-purpose ports on the switch as either 10/100/1000 Ethernet ports or as SFP module ports. You can set the 10/100/1000 Ethernet ports to autonegotiate, or you can configure them as fixed 10, 100, or 1000 Mb/s Ethernet ports.
By default, the switch selects the medium for each dual-purpose port (10/100/1000BASE-T or SFP). When a link is achieved on one media type, the switch disables the other media type until the active link goes down. If links are active on both media, the SFP module port has priority, but you can use the media-type interface configuration command to manually designate the port as an RJ-45 port or an SFP port.
You can configure the speed and duplex settings consistent with the selected media type. For information on configuring interfaces, see the “Interface Configuration” chapter of the Cisco Connected Grid Ethernet Switch Module Interface Card Software Configuration Guide on Cisco.com.
For more information on the SFP module ports see the “Supported SFPs” section on page 1-6 and the information on the SFP modules connectors and cables in the “Cable and Connectors” appendix.
Supported SFPs
Table 1-4 describes the supported SFP modules.
Note
The following SFP module slot points should be noted:
- The four 100 Mb/s FE SFP module slots of the Fiber model can only support 100FX connections.
- The 100/1000 Mb/s SFP module slots support both 100FX and 1000Base-X connections.

Router Compact Flash Memory Cards
Compact flash cards can help you configure new or replacement routers, and to recover the configuration of a failed router. For example, if the Connected Grid Swap Drive feature is enabled, you can transfer the same system configuration information from one router to another by using a compact flash memory card (or compact flash card) while the routers are operating. This is done by inserting an optional compact flash card in slot CF1 and copying all contents of CF0. After the copy operation is completed, you can remove and insert this compact flash card unit in slot CF0 of either a new router or a replacement router for a failed unit. When the new or replacement router is rebooted, it uses the configuration from the compact flash card as the running and startup configuration. This functionality enables you to quickly configure new or replacement routers with a standard configuration with little or no manual configuration required.
For more information on the Swap Drive feature, see:
http://www.cisco.com/en/US/docs/routers/connectedgrid/cgr2010/software/15_2_2_t/cgr2010_15_2_2_t_swcg.html#wp2039791
The router supports a maximum of two compact flash memory cards. The router ships with one compact flash card installed in Slot CF0 and supports a second, optional flash card that you can order with the router or supply separately.
Figure 5 illustrates the location of the compact flash card slots on the router.

- Step 4 Power up the router when ready to do so.
Express Setup
You access the switch module via the host CGR 2010 router. For more information, see Accessing the Switch Module, page 4-2.
To exchange and monitor control messages between the switch module and the router, a Router Blade Configuration Protocol (RBCP) stack operates concurrently on active IOS sessions running on both the host router and the switch module. You should use Express Setup to enter the initial IP information. You can then access the switch module through the IP address for further configuration.
This chapter contains the following topics:
- System Requirements
- Express Setup
- Troubleshooting Express Setup
- Resetting the Switch Module
Note
To use the CLI-based initial setup program, see Appendix A, “Creating an Initial Configuration with the CLI Setup Program,” in the Cisco Connected Grid Ethernet Switch Module Interface Card Software Configuration Guide.
System Requirements
You need the following software and cables to run Express Setup:
- PC with Windows 2000, XP, Vista, Windows Server 2003, or Windows 7
- Web browser (Internet Explorer 6.0, 7.0, or Firefox 1.5, 2.0, or later) with JavaScript enabled
- Straight-through or crossover Category 5 or Category 6 cable
Express Setup
Follow these steps to start Express Setup:
- Step 1
Disable any pop-up blockers or proxy settings on your web browser, and any wireless client running on your computer. - Step 2 Verify that no device is connected to the switch module.
- Step 3 Temporarily configure your computer to use DHCP, if it has a static IP address. The switch module acts as a DHCP server.
Tip Write down the static IP address, as you need this address in a later step.
- Step 4 Power on the CGR 2010 router. Once the host router is powered up, the router automatically powers up the switch model.
For more information, see “Powering Up the Router” in Chapter 4, “Configuring the Router,” in the
Cisco Connected Grid Routers 2010 Hardware Installation Guide.
Once the switch module powers on, it starts the Power-On Self-Test (POST), which can take up to two minutes.
- During POST, the System LED blinks green and then port LEDs turn green
- When POST is complete, the System LED remains green and the other LEDs turn off
Note If the System LED blinks green, does not turn green or turns amber, the switch module failed POST. Contact your Cisco representative or reseller.
- Step 5 Press the recessed Express Setup button with a simple tool, such as a paper clip. You might need to press the button for 3 seconds. When you press the button, the switch module 10/100 Ethernet port LED blinks green.
Figure 3-1 Recessed Express Setup Button
Note If a switch module port LED does not blink green, repeat Steps 1 to 5. You can also use the CLI setup program described in Appendix A, “Creating an Initial Configuration with the CLI Setup Program,” in the Cisco 2010 Connected Grid Ethernet Switch Module Interface Card Software Configuration Guide.
- Step 6 Select one of the following:
- For the Copper Model (GRWIC-D-ES-2S-8PC), connect a Cat 5 or 6 cable to the blinking 10/100BASE-T port, and the plug the other end to the Ethernet port on your computer
- For the SFP Fiber Model (GRWIC-D-ES-6S), connect a Category 5 or Category 6 cable to the 100/1000BASE-T port of the dual-purpose port (GE0/1), and then plug the other end to the
- Ethernet plug on your computer
Wait until the port LEDs on the switch module and your computer are either green or blinking green (indicates successful connection).
Tip If the port LEDs are not green after 30 seconds, verify you are using Cat 5 or 6 cable and that the cable is not damaged. Make sure the other devices are turned on. You can also verify the connection by pinging IP address 169.250.0.1.
Follow these steps to configure the switch module:
- Step 1 Open a web browser and enter the switch module IP address.
- Step 2 Enter cisco as the default username and password.
Figure 3-2 Express Setup Window
Tip If you cannot access Express Setup, verify that all pop-up blockers or proxy settings are disabled, and that any wireless client on your computer are disabled.
- Step 3 Enter the Network Settings values:
| Field | Description |
| Management Interface (VLAN ID) | Use the default setting of 1.
Note Enter a new VLAN ID only if you want to change the management interface for the switch module. The VLAN ID range is 1 to 1001. |
| IP Assignment Mode | Use the default setting of Static, which means that the switch module keeps the IP address.
Note Use the DHCP setting when you want the switch module to automatically obtain an IP address from the DHCP server. |
| IP Address | Enter the IP address of the switch module |
| Subnet Mask | Select a subnet mask from the drop-down |
| Default Gateway | Enter the IP address for the default gateway (router) |
| Switch Password | Enter your password. The password can be from 1 to 25 alphanumeric characters, can start with a number, is case sensitive, allows embedded spaces, but does not allow spaces at the beginning or end. |
| Confirm Switch Password | Enter your password again
Note You must change the password from the default password cisco. |
- Step 4 Enter the Optional Settings now, or enter them later using the Device Manager interface.
You can enter other administrative settings in the Express Setup window. For example, the optional administrative settings identify and synchronize the switch module for enhanced management. NTP synchronizes the switch module with the network clock. You can also manually set the system clock settings. - Step 5 Click Submit to save your changes.
The switch module is now configured and exits Express Setup. The browser displays a warning message and attempts to connect with the earlier switch module IP address. Typically, connectivity between the computer and the switch module is lost because the configured switch module IP address is in a different subnet for the computer IP address. - Step 6 Disconnect the switch module from the computer, and install the switch module in your network (see Installation, page 2-2).
- Step 7 If you have not changed your IP address, skip this step.
If you changed your IP address in the previous set of steps, change it to the previously configured IP address (see Step 3). - Step 8 Display the Device Manager:
- Open a web browser and enter the switch module IP address.
- Enter the username and password and then click Enter.
For more information on configuring and managing the switch module, see Accessing the Switch Module, page 4-2.
Note If the Device Manager does not display, check the following:
- Confirm that the LED for the switch module port connected to your network is green
- Confirm that the computer that you are using to access the switch module has network connectivity by connecting to a web server in your network. If there is no network connection, troubleshoot the network settings on your computer.
- Verify that the switch module IP address in the browser is correct. If it is correct, the port LED is green and the computer has network connectivity. Continue troubleshooting by disconnecting and then reconnecting the switch module to your computer. Configure a static IP address on the computer that is in the same subnet as the switch module IP address.
When the LED on the switch module port that connects to the computer is green, open a web browser and enter the switch module IP address to display the Device Manager. When the Device Manager displays, you can continue with configuration.
Troubleshooting Express Setup
If you are still have problems running Express Setup, perform the checks in Table 3-1.
Table 3-1 Troubleshooting Express Setup
| Problem | Resolution |
| POST did not complete before you started Express Setup | Verify that only the System and Port LEDs are green before you press the Express Setup button.
Note POST errors are usually fatal. Contact your Cisco technical support representative if your switch module fails POST. |
| Express Setup button was pressed before POST finished | Wait until POST completes, and then restart the switch module. Wait until POST completes again, and then confirm that the System and Port LEDs are green. Press the Express Setup button. |
| Computer has a static IP address | Change the settings on your computer to temporarily use DHCP |
| Ethernet is connected to the console port | Disconnect the cable from the Console port on the switch module. Connect the cable to a blinking 10/100 Ethernet port on the switch module. Wait 30 seconds, and then open a web browser.
Note The Console port is outlined in blue, and the Ethernet ports are outlined in yellow. |

The service-module gigabitEthernet 0/x/0 session command is the privileged EXEC mode command used to console into the Ethernet switch module from the host router.
You need to console into the switch module in order to configure it. In order to console into the switch module, you must configure an IP address on the internal backplane Gigabit Ethernet interface, that is, GE0/0/0 or GE0/2/0, connected to the switch module. If you try to console into the switch module without assigning an IP address, you receive the following error message:
Router1#service-module gigabitEthernet 0/2/0 session
IP address needs to be configured on interface GigabitEthernet0/2/0
To access the switch module from the host router:
| Command | Purpose | |
| Step 1 | Router> enable | Log into the Cisco CGR 2010 router in privileged EXEC mode.
Enter your password if prompted. |
| Step 2 | Router# show running interface gigabitethernet0/<slot>/0 | Displays the running interface of the router, which should have a Gigabit Ethernet interface representing the switch module. |
| Step 3 | Router# configure terminal | Enters global configuration mode. |
| Step 4 | Router(config)# interface gigabit ethernet 0/<slot>/0 | Enters interface configuration mode, and specifies the Gigabit interface used to access the switch module. |
| Step 5 | Router(config-if)# ip address
20.0.0.1 255.255.255.0 |
Configures the IP address and subnet mask for the interface. |
| Step 6 | Router(config-if)# no shutdown | Enables the switch module port. |
| Step 7 | Router(config-if)# end | Returns to privileged EXEC mode. |
| Step 8 | Router# service-module
<interface><slot/subslot/port > session Example: Router> service-module gigabitethernet0/<slot>/0 session |
Establishes a session from the router over the internal backplane Gigabit Ethernet interface to the switch module. |
| Step 9 | Switch# | After you execute the service-module <interface> session command, the switch module prompt appears and you have full access to the switch module. |
Disconnecting from the Switch Module
To disconnect from the switch module and return to the host Cisco CGR 2010 router:
| Command | Purpose | |
| Step 1 | Switch> enable | Enters privileged EXEC mode on the switch module. |
| Step 2 | Switch# show ip interface brief | Displays the brief version of the switch module configuration information. |
| Command | Purpose | |
| Step 3 | Switch# <Ctrl+Shift+6> x | Press <Ctrl+Shift+6>, then press x.
This sequence returns you to the router console while keeping the console session to the switch module intact and then exits the console session to the switch module. |
| Step 4 | Router# disconnect | Terminates the console session to the switch module. |
| Step 5 | Router# <Enter> | Press Enter to confirm the disconnect. |
| Step 6 | Router# service-module gigabit ethernet 0/0/0 status | Displays the status of all the vital components of the switch module. For example output, see the “Service-Module Command Syntax” section in Chapter 3, “Accessing the Switch Module From the Host Router” in the Cisco 2010 Connected Grid Ethernet Switch Module Interface Card Software Configuration Guide. |
Connecting Devices to the Switch Module
This section describes how to connect various devices to the switch module ports.
Tip
If you cannot reach the bale-clasp handle with your fingers when removing RJ-45 or SFP cables from the switch module, use the straight tool provided to gently release the bale-clasp handle.

10/100BASE-T Ports
Follow these steps to connect to the 10/100BASE-T ports:
- Step 1 When you connect to servers, workstations, IP phones, wireless access points, and routers, use a straight-through, twisted four-pair, Category 5 cable to connect to the 10/100BASE-T RJ-45 connector.
Use a crossover, twisted four-pair, Category 5 cable when you connect to other switches, hubs, or repeaters.
Note The first four 10/100BASE-T ports on the GRWIC-D-ES-2S-8PC switch module have PoE+ capability. See the Cisco Connected Grid Ethernet Switch Module Interface Card Software Configuration Guide for more information.
Figure 4-1 RJ-45 Ports
- Step 2 Connect the cable to the RJ-45 port on the other device.
Note The automatic medium-dependent interface crossover (auto-MDIX) feature is enabled by default. The switch detects the required cable type for copper Ethernet connections and configures the interfaces. You can use either a crossover or a straight-through cable for connections to a 10/100/1000 RJ-45 port on the switch module, regardless of the type of connected device.
SFP Module Slots
The switch module provides two 100/1000 Mb/s or Gigabit Ethernet SFP module slots ports: one standard Gigabit SFP module slot in the center (labeled GE0/2) and one SFP module slot for the dual-purpose port on the bottom (labeled GE0/1).
To connect to an SFP module slot:
- Step 1 Grasp the SFP module on the sides, and insert it into the SFP module slot port until you feel the connector snap into place.
Caution Make sure that SFP module is right side up before attempting to insert the SFP module into the slot.
Figure 4-2 SFP Module Ports
- Step 2 Connect the SFP cable into the SFP module slot, and insert the other cable end into the other device.
Figure 4-3 Connecting the Cable into the SFP Port
For detailed instructions on installing, removing, and connecting to SFP modules, see the SFP module documentation.
Dual-Purpose Port with RJ-45 and SFP Connectors
The Gigabit Ethernet port GE0/1 on the switch module consists of a pair of one RJ-45 connector (topmost port) and one SFP module connector (bottom port).
This dual-purpose port is considered as a single interface. The two connectors are not redundant interfaces—the switch module activates only one connector of the pair at a time.
If the dual-purpose port is configured as media-type RJ-45, the speed of the connection can be manually set to either 10, 100 or 1000 Mb/s (10/100/1000BASE-T specifications). The default speed setting is always enabled to AUTONEGOTIATION. It will automatically negotiate to whatever speed is set on the other end of the connection.
If the dual-purpose port is configured as media-type SFP, the speed is dependent on the module type you are using, either a 100FX or a 1000BASE-X SFP module. The port will automatically detect the module, and the speed is set based on the media type. The other end of the connection will have to be of the same media type in order to establish the link.
Note
Even when operating at 100 Mb/s, the dual-purpose ports (and the SFP-only module slots) use the frame size that is set with the system mtu jumbo global configuration command. By default, the dual-purpose ports and the SFP-only module slots are network node interfaces (NNIs).
By default, the switch module dynamically selects the dual-purpose port media type that first links up. However, you can use the media-type interface configuration command to manually select the RJ-45 connector or the SFP module slot.
Note
In auto-select mode, if both copper and fiber-optic signals are simultaneously detected, the switch module gives preference to SFP mode. For configuration information, see “Configuring a Dual-Purpose Port” in Chapter 8, “Configuring Interfaces,” in the Cisco 2010 Connected Grid Ethernet Switch Module Interface Card Software Configuration Guide.
The following illustration shows an Ethernet cable connected to the RJ-45 connector of the dual-purpose port (GE0/1). It also shows an SFP cable connected to the standard SFP module slot (GE0/2).
Figure 4-4 Ethernet Cable Connected to the RJ-45 Connector
Figure 4-5 shows both connectors of the dual-purpose port being used. In this case, with both an RJ-45 cable and an SFP module cable in their respective GE0/1 ports, the switch module will provide reference to the SFP module slot.

Verifying Port Connectivity
After you connect the switch module port and another device, the port LED turns amber while the switch module establishes a link. This process takes about 30 seconds, and then the LED turns green. If the LED turns off, the target device might not be turned on, there might be a cable problem, or there might be a problem with the adapter in the target device.
FAQ
What should I do if the switch module fails POST?
If the System LED blinks green, does not turn green, or turns amber, indicating a failed POST, contact your Cisco representative or reseller for assistance.
How do I troubleshoot if the port LEDs are not green after 30 seconds?
Verify that you are using Cat 5 or Cat 6 cable, ensure the cable is not damaged, make sure other devices are turned on, and try pinging IP address 169.250.0.1 to verify connection.
