Chapter 3 Maintaining the Server
Installing or Replacing Server Components
To install or replace a CPU heatsink and CPU, follow these steps:
Step 1 Remove the CPU and heatsink that you are replacing:
a. Power off the server as described in the “Shutting Down and Powering Off the Server” section on
page 3-6.
b. Slide the server out the front of the rack far enough so that you can remove the top cover. Y ou might
have to detach cables from the rear panel to provide clearance.
Caution If you cannot safely view and access the component, remove the server from the rack.
c. Remove the top cover as described in “Removing and Replacing the Server Top Cover” section on
page 3-7.
d. Remove the internal air baffle from the server to provide access to the CPUs.
e. Use a #2 Phillips-head screwdriver to loosen the four captive screws that secure the heatsink and
then lift it off of the CPU.
Note Alternate loosening each screw evenly to avoid damaging the heatsink or CPU.
f. Unclip the CPU retaining latch, then open the hinged CPU cover plate. See Figure 3-13.
