Check the Router Component Status

When you check the router craft interface, the component LEDs, and the environmental and operational information, you are either physically inspecting the components or obtaining output about their status from commands you issue from the CLI.

To check router component status:

1. Check the Router Craft Interface
2. Check the Component LEDs
3. Display Detailed Component Environmental Information
4. Display Detailed Component Operational Information

Check the Router Craft Interface

Purpose

To confirm that the craft interface is functioning properly by checking the alarm indicator status or by checking the craft interface physically.

Action

To check the router craft interface, do one of the following:

• Use the following command:
  user@host> show chassis craft-interface

  The command output displays the router alarm indicator status, the LCD display information (router name, router uptime, and status message that rotates at 2-second intervals), and the major component LED status. Table 1 describes the command output for each router type. For more detailed information about the craft interface, see Checklist for Monitoring the Craft Interface .

Check the Component LEDs

Purpose

To confirm that the component LEDs are functioning properly by checking the output messages, by physically checking the craft interface or examining the LEDs on the component faceplate.

Action

To check the component LED status, do one of the following:

• Use the following command:
  user@host> show chassis craft-interface

  The command output displays the LED status for the following components:

  • M7i/M10i/M20 router: Routing Engine and FPC
  • M40e/M160 router: Routing Engine, FPC, MCS, PCG, and SFM
  • M120 router: Routing Engine. Alarms, FPC, Control Board, power supply (PS), and FEB
  • M320 router: Routing Engine, FPC, Control Board, SIB, and power supply (PS)
  • T320, T640, T1600 routers: Routing Engine, FPC, Control Board, SCG, and SIB
• Physically look at the craft interface. You see the following component LEDs:
  • M5/M10, M20, and M40 routers: Routing Engine
  • M40e/M160 routers: Host module
  • M120 router: Routing Engine. Alarms, FPC, Control Board, power supply (PS), and FEB
  • T320, T640 and T1600 routers: Alarms, host subsystem, FPCs, and SIBs
  • TX Matrix and TX Matrix Plus routers: Alarms, host subsystem, and SIBs
• Look at the LEDs on the component faceplate. Table 4 describes where the LEDs are located on the router.

Display Detailed Component Environmental Information

Purpose

To check the component environmental information for the uptime to determine if it is functioning properly.

Action

To display detailed environmental status information about a component, use the following command:

The command output displays the temperature of the air passing by the component, in degrees Centigrade and Fahrenheit. It also displays whether the fans and/or blowers are at normal or high speed.

Table 5 lists the operational mode commands for each router component for which you can display more detailed information.

Display Detailed Component Operational Information

Purpose

To check the component environmental information for the uptime to determine if it is functioning properly. This feature is available on all routing platforms except the M5/M10, M20, and M40 routing platforms.

Action

To display detailed operational information about a component, use the following command:

The command output displays the temperature of the air passing by the component, in degrees Centigrade and Fahrenheit. It displays the total percentage of CPU, interrupt, heap space, and buffer space being used by the component processor, including the total DRAM available to the component processor. The command output displays the time when the component started running and how long the component has been running. A short uptime can indicate a problem with the component.

Table 6 lists the components for which you can display more detailed operational status information.
