Troubleshooting the Power System on the SRX3600 Services Gateway
To verify that a power supply is functioning normally, perform the following steps:
•
Check the LEDs on each power supply faceplate. If a power supply is correctly installed and functioning
normally, the LED on the power supply faceplate blinks green while the services gateway is booting up,
and lights steadily green once the services gateway has finished booting.
•
Issue the CLI show chassis environment pem command to check the status of installed power supplies.
As shown in the sample output, the value Online in the rows labeled State indicates that the power
supplies in slots 0 through 3 are functioning normally:
user@host>show chassis environment pem
If a power supply is not functioning normally, perform the following steps to diagnose and correct the
problem:
•
If a red alarm condition occurs, issue the show chassis alarms command to determine the source of the
problem.
NOTE: If the system temperature exceeds the 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.
•
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 AC
