Maintaining the MX960 Power Supplies
date_range
09-Mar-21
Action
On a regular basis:
Check the status of the power supplies by issuing the show chassis environment pem command. The output is similar to the following:
content_copy zoom_out_mapuser@host> show chassis environment pem PEM 0 status: State Online Temperature OK DC output OK PEM 1 status: State Online Temperature OK DC output OK
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 power supply faceplates and the craft interface to determine if the power supplies are functioning normally.
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:
content_copy zoom_out_mapuser@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.
