The Indicator of a Fan Module Is Steady Red or Blinking

Fault Description

The indicator of a fan module is steady red or blinking.

Possible Causes

  • The fan module is not properly installed in the fan slot.
  • Fan blades are blocked or stop rotating because of heavy dust.
  • The fan module is faulty.

Troubleshooting Procedure

  1. Check whether the fan module is securely installed. If not, remove and reinstall the fan module (hot swappable).
  2. Remove the fan module and check whether fan blades are blocked or covered with heavy dust.
    • If fan blades are blocked by an obstacle, remove the obstacle.
    • If fan blades have heavy dust, use a brush to clean fan blades.
  3. Install another fan module of the same model into the fan slot. If the new fan module can work normally, the original fan module has failed.
