Check the red and yellow alarm LEDs on the craft interface. Power supply 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.
CAUTION: Do not mix AC and DC power supplies in the same chassis.
