- Routinely check the status LEDs on the AC or DC PSM faceplates and the craft interface to determine if the PSMs are functioning normally.
- Check the red and yellow alarm LEDs on the craft interface.
PSM failure or removal triggers an alarm that causes one or both of
the LEDs to light. You can display the associated error messages by
issuing the following command:
user@host> show chassis alarms - Periodically inspect the site to ensure that the grounding and power cables connected to the router are securely in place and that there is no moisture accumulating near the router.
