If you are replacing a server component in the server, you need to turn off the server and peripheral devices, and disconnect the power cords and all external cables.

To install a heat sink retention module, complete the following steps.

1. Carefully turn the server on its side so that it is lying flat, with the cover facing up.
   Attention

   Do not allow the server to fall over.
2. Unlock and remove the left-side cover (see Removing the left-side cover).
3. Remove the air baffle (see Removing the air baffle).
4. Position the heat sink over the microprocessor. The heat sink is keyed to assist with proper alignment.
5. Align the heat sink to the retainer bracket tabs and place the heat sink on top of the microprocessor, thermal material side down.
