Red

On

Indicates failure of one or more PSUs.

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 http://www.juniper.net/support/, or call 1-888-314-JTAC (within the United States) or 1-408-745-9500 (outside the United States).

Off

Indicates that the services gateway is not receiving power.

If a red alarm condition occurs, issue the show chassis alarms command to determine the source of the problem.

• Verify that the AC power cord and/or DC power supply cable is not damaged. If the insulation is cracked or broken, immediately replace the cord or cable.
• Verify that the source circuit breaker has the proper current rating. Each power supply must be connected to a separate source circuit breaker.
• Ensure that the power socket you are plugged into is in working condition.
• 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.

Note: If the system temperature exceeds the threshold, the Junos OS shuts down all power supplies so that no status is displayed.

The 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.
