1.4.3 FAN module

I. Functions

The 3Com Router 6040 is configured with six fans; the 3Com Router 6080 is configured with eight fans. These fans are working in pairs and the two fans in each pair are working in redundancy. When all these fans are working normally, the operating temperature of the system can be maintained between 0 and 55oC (32 to 131oF). As the failure of a fan does not affect the operation of other fans, the normal operating temperature of the system can maintain.

The routing speed of the fans is adjusted by the fan controller on the main control board and between 50% and 100% depending on the system temperature. When the system temperature rises above the high-temperature threshold set by the fan controller, the fans are rotating at full speed (100%); when the system temperature drops below the low-temperature
