SRX650 Services Gateway Cooling System

The fan controller is the cooling system component provided in the SRX650 Services Gateway to keep all components within the acceptable temperature range.

The services gateway has a single fan tray that contains four 80 mm fans.

The fan controller constantly monitors the temperature of the services gateway and all modules (SRE or GPIMs) installed in the device at any given time. Under normal operating conditions, the fans function at lower than full speed.

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 specification exceeds the warning limit and the system cannot be adequately cooled, then the services gateway shuts down the system and hardware components completely.
