O O The rewall is not
receiving power.
Issue the show chassis alarms command
to determine the source of the problem.
Verify that the AC power cord or DC
power supply cable is not damaged.
If the insulaon is cracked or broken,
immediately replace the cord or
cable.
Verify that the source circuit breaker
has the proper current rang. Each
PSU must be connected to a
separate source circuit breaker.
Ensure that the power socket into
which you have plugged the device is
working.
Connect the PSUs to a dierent
power source with a new power cord
or power cables. If the LEDs on the
PSUs indicate that the PSU is not
funconing normally, replace the
PSU with a spare.
NOTE: If the system temperature
exceeds the threshold, Junos OS shuts
down all the PSUs and the LED stops
indicang the status.
Junos OS also can shut down one of the
PSUs for other reasons. In this case, the
remaining PSU provides power to the
rewall. You can view the system status
through the CLI.
