Router LED Locations and States

This section describes the Cisco 1240 Connected Grid Router (CGR 1240 or router) LEDs and how to determine the overall state of the system and verify the status of specific connections, ports, and system components.

In addition to viewing the LEDs on the router hardware, you can use the router command line interface as described in Related Commands to check the system status LED state from remote locations.

These topics are discussed:

LED Locations and State Descriptions

SYS LED—System Status

View the system status LED to determine the overall operating and power status of the router.

A second, identical system status LED is located inside the router. See the Alarm and Network Connection LEDs for the location of the interior SYS LED.

Alarm and Network Connection LEDs

The router LEDs that indicate network activity and connection status, and the LEDs that indicate alarm states, are located inside the router. To see these LEDs, you must open the router chassis according to the instructions in Opening and Closing the Router Chassis.

Battery Backup Unit LED

The router supports up to three battery backup units (BBUs). When two or more BBUs are installed, they are connected to each other in a head-to-tail configuration in the router and the BBU LED are in the locations shown in Figure 101.

To see the LED for each BBU, open the router chassis as described in Opening and Closing the Router Chassis.

Related Commands

Commands related to displaying LED status information for the different operating systems (Cisco CG-OS and Cisco IOS) used on the CGR 1240 router are presented in this section.

An example of the usefulness of the command is that during normal operation, the router can be installed at the top of an outdoor pole or other inaccessible location, and you may not be able to view the SYS LED on the router hardware. In this case, you can view the status of the LED from a remote location using the router CLI.

The range of commands presented includes:

■blank.gifDisplaying Router SYS LED Status Command

■blank.gifDisplaying Interface Status Command

Displaying Router SYS LED Status Command

A show command can be used to display the SYS LED status in text format. There are two SYS LEDs on the CGR router: the first SYS LED is located on the router exterior (see Figure 99) and the second is inside the router chassis (see Figure 100). Table 32 describes the SYS LED status.

The operating system show commands are:

■blank.gifCisco CG-OS show led Command

■blank.gifCisco IOS show platform led Command

Cisco CG-OS show led Command

On a CGR 1240 router using the Cisco CG-OS operating system, use the show led command in any command mode to view the status of the router SYS LED.

This example shows the show led command output:

CGR1240> show led
System LED: green, solid

Cisco IOS show platform led Command

On a CGR 1240 router using the Cisco IOS operating system, use the show platform led command in global configuration mode to view the status of the router SYS LED.

Displaying Interface Status Command

The Cisco CG-OS and Cisco IOS operating systems use the show interface command to display status information about the router interfaces in privileged EXEC mode.
