2.6.2 Fan Modules
This section describes the slot numbers and features of fan modules in the E9000.
Function
The E9000 provides 14 fan modules, which are divided into three zones, with each fan
module containing two fan units. Each zone supports N+1 redundancy, ensuring heat
dissipation is not affected if a fan unit or module fails. The E9000 chassis uses forced air
cooling technology and front-to-rear ventilation channels. This ensures that the air enters the
chassis from the front and exits from the rear. The fan modules automatically adjust the fan
speed based on the operating temperature of compute nodes in the chassis or the management
module adjusts the fan speed.
