Maintaining the MX960 Host Subsystem

 

Purpose

For optimum router performance, verify the condition of the host subsystem. The host subsystem includes an SCB and a Routing Engine installed into a slot in the SCB.

Action

On a regular basis:

  • Check the LEDs on the craft interface to view information about the status of the Routing Engines.

  • Check the LEDs on the SCB faceplate (see Table 9 in SCB-MX Description).

  • Check the LEDs on the Routing Engine faceplate (see Table 10 in MX960 Routing Engine Description).

  • To check the status of the Routing Engines, issue the show chassis routing-engine command. The output is similar to the following:

    user@host> show chassis routing-engine
  • To check the status of the SCBs, issue the show chassis environment cb command. The output is similar to the following:

    user@host> show chassis environment cb

To check the status of a specific SCB, issue the show chassis environment cb command and include the slot number of the SCB—for example, show chassis environment cb 0.
