SRX 5600 Services Gateway Hardware Guide
If a power supply is not functioning normally, perform the following steps to diagnose
and correct the problem:
NOTE: If the system temperature exceeds the threshold, the JUNOS software shuts
down all power supplies so that no status is displayed.
The JUNOS software also can shut down one of the power supplies for other reasons.
In this case, the remaining power supplies provide power to the services gateway,
and you can still view the system status through the CLI or display.

Verify that the source circuit breaker has the proper current rating. Each power
supply must be connected to a separate source circuit breaker.
Verify that the AC power cord or DC power cables from the power source to the
device are not damaged. If the insulation is cracked or broken, immediately
replace the cord or cable.
Connect the power supply to a different power source with a new power cord
or power cables. If the power supply status LEDs indicate that the power supply
is not functioning normally, the power supply is the source of the problem.
Replace the power supply with a spare, as described in "Replacing Power System
Components" on page 133.
