Maintaining SRX5800 Services Gateway Power Supplies
Purpose
For optimum services gateway performance, verify the condition of the power supplies.
Action
On a regular basis:
•
To check the status of the power supplies, issue the show chassis environment pem command. The
output is similar to the following:
user@host>
show chassis environment pem
PEM 0 status:
State Online
Temperature OK
AC Input: OK
DC Output Voltage Current Power Load
50 6 300 17
PEM 1 status:
State Online
Temperature OK
AC Input: OK
DC Output Voltage Current Power Load
50 3 150 8
•
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.
•
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 device are
securely in place and that there is no moisture accumulating near the device.
