Why is the indicator of a fan module steady red or blinking red on CE switches
Possible Causes 1. The fan module is not installed properly in the fan slot. 2. Fan blades are blocked or stop rotating because of heavy dust. 3. The fan module is faulty. Troubleshooting Procedure 1. Pull out the fan module and reinstall it to ensure that it is securely installed in the slot. (Fan modules are hot swappable.) 2. Remove the fan module from the chassis and check whether the fan blades are blocked or whether there is too much dust on the fan blades. a. If fan blades are blocked by an obstacle, remove the obstacle. b. If the fan blades have heavy dust, use a brush to clean them. 3. If the problem persists, install another fan module of the same model into the fan slot. If the new fan module can work properly, the original fan module has failed and needs to be replaced.
