Fan module overview
The fan modules provide air cooling for the device. Each device contains three fan modules. Each fan module for the ExtremeRouting
SLX 9850-8 device contains four fans. The fan airow enters from the port side and exits from the fan side of the device.
For a description of the fan module LEDs, refer to Interpreting fan module LEDs on page 83.
This section describes the procedures you perform to remove and insert a fan module.
Precautions specic to the fan module
The device can continue to operate during the fan replacement procedure for 20 minutes. If the system reaches an over temperature
condition, it automatically sends a warning message. When the critical temperature is reached, the system shuts down.
NOTE
The ambient intake temperature of the system must be less than 35 deg C (95 deg F) at sea level to prevent overheating. If the
ambient temperature is greater than 35 deg C, the module installation time must be reduced. Refer to the specic module
