SRX1500 Cooling System

The services gateway has a single fan tray that contains four fixed fans. The fan controller constantly monitors the temperature of the services gateway and its components. Under normal operating conditions, the fans function at lower than full speed. Note that the fan tray is not field-replaceable.

If any one of the four fans fails, the services gateway generates a warning but keeps the system running. If the temperature keeps rising, the services gateway lowers the power consumption by reducing the performance or shutting down some of the chassis components. However, if the ambient maximum temperature exceeds the warning level and the system cannot be adequately cooled, then the services gateway shuts down the system and hardware components completely.
