  Functions

  Function	Description
  Hot swapping	Supported Other fan modules are not affected when you install or remove a fan module.
  Intelligent fan speed adjustment	The S7703, S7706, and S7712 series switches provide intelligent fan speed adjustment based on temperature in each zone, and correlate speeds of fans in the entire chassis. The system monitors the temperature of key components, and adjusts the fan speed based on temperature changes. This intelligent fan speed adjustment function ensures that the system stays within the proper operating temperature range, and reduces power consumption and noise.

  A fan module has two fans, and a failure of a fan does not immediately affect system operations. When any fan in a fan module fails, fix the fan module as soon as possible.
