Make sure that the power and grounding cables are arranged so that they do not
obstruct access to other router components.
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.

For optimum router performance, verify the AC or DC power usage.
On a regular basis:
Make sure that the total system power consumption and capacity doesn't exceed the
maximum allocated.
Issue the show chassis power
DC power system.
The output displays the AC chassis power for 2100 W capacity.
