Part # Cisco UBR10-FAN-ASSY

Product Description: The Cisco uBR10012 Universal Broadband Router uses a fan assembly module and contains four fans which supply cooling air to the chassis. The fan assembly is located at the top of the chassis and is connected to the chassis with a blind mate connector that plugs into a cable assembly and then into the chassis backplane. Four internal fans draw cooling air into the front of the chassis and direct it across the internal components to maintain an acceptable operating temperature. The air is exhausted through openings in the rear of the chassis.

The fan assembly module works at variable speeds: low speed (with a clean air filter) at approximately 280 cubic feet per minute (cmf) and high speed (with a clean air filter) at approximately 450 cmf. The operating speed is determined by the fan assembly module. If the temperature at the fan's outlet gets to 40C, then the blower starts to increase the speed of the fans. It does not reach high speed, however, until the temperature at the outlet reaches 50C. Three LEDs (System OK, Single Fan Failure, and Multi-Fan Failure) located on the front of the fan assembly indicate the status of the fans.
