Troubleshooting the Cooling System on the SRX3600 Services Gateway
The services gateway cooling system consists of a fan tray and an air filter, both of which are located
vertically in the rear of the chassis. The fan tray contains 10 fans. The fan tray provides cooling to the
components installed in the services gateway.
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 SRX3600 Services Gateway”
on page 65.
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 services gateway components, adjusting
the speed of the fans as necessary. If the services gateway temperature exceeds the acceptable maximum,
the Routing Engine turns off the power supplies. The following conditions automatically cause the fans to
run at full speed and also trigger the indicated alarm:
