Juniper SRX-4600, Hardware Manual

If a power supply is not functioning normally, perform the following tasks to diagnose and correct the
problem:
•
If a red-alarm condition occurs, use the show chassis alarms command to determine the source of the
problem.
NOTE: If the system temperature exceeds the red-alarm threshold, Junos OS shuts down
all power supplies so that no status is displayed.
Junos OS 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 J-Web interface.
NOTE: The services gateway shuts down automatically if the device temperature exceeds
the red-alarm threshold.
•
Check that the AC input switch (—) or DC circuit breaker (|) is in the on position and that the power
supply is receiving power.
•
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 services gateway 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 an
SRX4600 Services Gateway AC Power Supply” on page 91 or “Replacing an SRX4600 Services Gateway
DC Power Supply” on page 95 .
•
Verify that power supply is functioning properly by checking the status of power supply LED. For more
information, see “SRX4600 Power System” on page 35 .
•
If you cannot determine the cause of the problem or need additional assistance while troubleshooting
a services gateway, open a support case using the Case Manager link at: https://www.juniper.net/support/
