the microprocessor. The outermost dots must be within approximately 5 mm of the edge of the
microprocessor, this is to ensure uniform distribution of the grease.
Note: If the grease is properly applied, approximately half of the grease will remain in the syringe.
6. Install the heat sink onto the microprocessor as described in “Installing a microprocessor and heat
sink” on page 189.

Step 2. Turn off the server and all attached devices; then, disconnect all power cords and external cables.
Step 3. Carefully lay the server on its side so that it is lying flat and facing up.
Note: Do not allow the server to fall over.
Step 4. Unlock and remove the side cover (see “Removing the side cover” on page 146).
