Maintaining the T640 SIBs



For optimum router performance, verify the condition of the SIBs.


On a regular basis:

  • Observe the status of the SIBs by checking the LEDs on the SIB faceplate. During normal operations:

    • The green OK LED on the SIB faceplate is lit.

    • The yellow FAIL LED on the SIB faceplate is not lit.

  • To check the status of the SIBs using the CLI, issue the show chassis environment sib command. The output is similar to the following:

    user@host> show chassis environment sib

For more information about using the command, see show chassis environment sib.
