There are two classes of alarm messages:
Chassis alarms—Indicate a problem with a chassis component such as the cooling
system or power supplies.
Interface alarms—Indicate a problem with a specific network interface.
If you need assistance while troubleshooting a services gateway, open a support case
using the Case Manager link at:
(within the United States) or 1-408-745-9500 (from outside the United States).

The services gateway cooling system consists of a fan tray and an air filter, both of which
are located in the side of the chassis and plugged in from the rear of the chassis. The fan
tray contains two fans. The fan tray provides cooling to the components installed in the
device.
An air filter installed in the rear of the chassis helps keep dust and other particles from
entering the cooling system. To function properly, the entire cooling system requires an
unobstructed airflow and proper clearance around the site, as described in "Site
Preparation Checklist for the SRX1400 Services Gateway" on page 41.
During normal operation, the fans in the fan tray function at less than full speed. The
Routing Engine constantly monitors the temperatures detected by sensors and device
components, adjusting the speed of the fans as necessary. If the device temperature
exceeds the acceptable maximum, the Routing Engine turns off the power supplies.
Table 34 on page 106 describes the alarm conditions and corrective actions for SRX1400
Services Gateway cooling system.
