Install a Fan

1. Identify the prerequisite and subsequent service tasks you must perform in conjunction with this procedure.

   See Servicing the Fans.

2. Inspect the replacement fan.

   See Inspecting a Fan.

3. Verify that the slot where the fan installs is clean and free of debris.

4. Verify that the slot connector pins are straight and not missing.

5. Orient the fan over the opening in the switch chassis with the thumbscrew on the right.

6. Firmly slide the fan into the chassis until the fan stops.

   
   

   The fan might immediately power on.

7. Tighten the captive thumbscrew to secure the fan in the switch chassis.

   
   

8. Verify that the fan Attention LED goes out.

9. Use the getfanspeed command on the management controller to verify the fan’s operation.

   For example, to check the fans:

   # getfanspeed
   Fan 0 rpm 14270
   Fan 1 rpm 14270
   Fan 2 rpm 14270
   Fan 3 rpm 14270
   Fan 4 rpm 14434
