•
The services gateway temperature exceeds the “temperature warm” threshold (yellow
alarm).
• The temperature of the services gateway exceeds the maximum (“temperature hot”)
threshold (red alarm and automatic shutdown of the power supplies).
To troubleshoot the fans, follow these guidelines:
•
If the FAN LED on the SFB lights red, use the CLI to get information about the source
of an alarm condition:
user@host> show chassis alarms
If the CLI output lists only one fan failure, and the other fans are functioning normally,
the fan is most likely faulty and you need to replace the fan tray, as described in
“Replacing the Fan Tray on the SRX3400 Services Gateway” on page 112 .
• Place your hand near the exhaust vents at the side of the chassis to determine whether
the fans are pushing air out of the chassis.
•
If all power supplies have failed, the system temperature might have exceeded the
threshold, causing the system to shut down.

Troubleshooting IOCs and NP-IOCs on the SRX3400 Services Gateway
To troubleshoot an IOC or NP-IOC, follow these guidelines:
•
Make sure the IOC or NP-IOC is properly seated in the midplane and its screws are
tightened.
• Issue the CLI show chassis fpc command to check the status of installed IOCs and
NP-IOCs. As shown in the sample output, the value Online in the column labeled State
indicates that the IOC or NP-IOC is functioning normally:
