Maintaining the Power Supplies

To check the status of the power supplies, issue the
command. The output is similar to the following:
pem
user@host> show chassis environment pem
PEM 0 status: State
OK
State
OK DC output
Make sure that the power and grounding cables are arranged so that they do not
obstruct access to other services gateway components.
Routinely check the status LEDs on the power supply faceplates and the craft
interface to determine if the power supplies are functioning normally. For more
information about the power supply LEDs, see "Power Supply LEDs" on page
25 and "AC Power Supply LEDs" on page 29 or "DC Power Supply LEDs" on
page 31.
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
For a list of possible alarm messages, see "Chassis and Interface Alarm Messages"
on page 93.
Periodically inspect the site to ensure that the grounding and power cables
connected to the device are securely in place and that there is no moisture
accumulating near the device. To review grounding and site wiring requirements
for the device, see "Preparing the Site for Services Gateway Installation" on page
