Hot-Swap Fan Assembly

  Replace a fan that has failed within 48 hours to help ensure proper cooling.

Note: You do not need to turn off the power to the server to replace a hot-swap fan assembly.

The following illustration shows the replacement of a hot-swap fan assembly. Refer to this illustration while performing the steps in this procedure.

To replace a hot-swap fan assembly:

 
The power cable to the fan should be disconnected whenever the fan assembly is not installed in the server. Otherwise, the fan might start turning while you are holding it and the fan blades could injure the fingers.

1.  Remove the top cover (see 'Top Cover Removal').

    
    To ensure proper system cooling, the top cover  should be removed for no more than 30 minutes  during this procedure.

2.  Determine which fan assembly -2-, -3-, or -5- needs  to be replaced by checking the fan LEDs on the  diagnostic panel (see 'Diagnostics Panel LEDs').
3.  Disconnect the fan power cable -1- from the fan  assembly that you are replacing.
4.  Turn the quarter-turn fastener -6- for the fan  assembly one quarter turn and remove the fan  assembly from the server.
5.  Slide the replacement fan assembly into the server.  (If you are replacing fan assembly 1 -3-, make sure  the tabs -4- fit into the slots at the bottom of the fan  opening in the server.)
6.  When you have the fan assembly correctly seated,  turn the quarter-turn fastener -6- one quarter turn to  secure the fan in the server.
7.  Connect the fan power cable -1- to the power  connector.
