Chapter 3 Maintaining the Server
Installing or Replacing Server Components
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.
Note
You 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 all memory risers to uncover the CPU cage screws. See Replacing Memory Risers,
page 3-26 .
e.
Remove all the memory riser dividers by lifting them straight up and sliding them free of the CPU
cage. See
Figure 3-14 .
f. Remove the CPU cage by loosening the six captive screws that secure the cage to the motherboard.
See
Figure 3-14 for the screw locations.
g.
Loosen the two captive screws that secure the heatsink and lift it off of the CPU. See Figure 3-14
and Figure 3-15 .
Note
Alternate loosening each screw evenly to avoid damaging the heatsink or CPU.
h.
Unclip the CPU retaining lever and lift the CPU retaining lid. See Figure 3-15 .
i. Lift the CPU out of the socket and set it aside on an antistatic mat or in an antistatic bag.
Step 2
Install a new CPU:
a. Insert the replacement CPU in the socket with the arrow on the CPU pointing toward the arrow on
the socket.
b.
Close the CPU retaining lid and clip down the CPU retaining lever.
Step 3 Install a heatsink:
Caution
The heatsink must have a new, undamaged thermal pad on the heatsink-to-CPU surface to ensure proper
cooling. If you are replacing a heatsink that was previously installed, you must remove the old thermal
pad. If you are installing a new heatsink, skip to step
d. below.
a.
Apply the supplied cleaning solution to the old thermal pad and let it soak for a least 15 seconds.
b. Wipe all of the old thermal pad off the heatsink using a soft cloth that will not scratch the heatsink
surface.
Caution
Damage to the heatsink surface can damage the heat transferring properties of the heatsink.
c.
Apply the supplied preparation solution to the center bottom of the heatsink, where the new thermal
pad will be applied.
