Step 6. Disconnect the AC power cords from the server rear panel.
Removng Server Components
To upgrade the server, remove the following components:
Step 1. Extend the server from the rack. See “Extend the Server from the Rack” on page 9.
Step 2. Remove the front bezel. See “Removing the Front Bezel” on page 13.
Step 3. Remove the front and top covers. See “Removing the Front Cover” on page 15 and “Removing the
Top Cover” on page 17.
Step 4. Remove the processor extender board. See “Removing the Processor Extender Board” on page 18
Step 5. Remove the center hot-swap chassis fan. See “Removing a Hot-Swap Chassis Fan Unit” on page 21.
Replacing the Processor Module(s)
This section provides information about removing the processor extender board from the chassis, replacing
the CPU module or modules, and reinstalling the processor extender board. The processor extender board is
located under the top cover of the server.
A processor extender board may contain one, two, three or four CPU modules. When upgrading a server to
include new processors, all CPU modules of the server must be upgraded together. You must not mix CPU
modules that include different types of processors.
WARNING Voltages are present at various locations within the server whenever an AC power
source is connected. This voltage is present even when the main power switch is in
the OFF position.
Ensure that the system is powered-down and all power sources have been
disconnected from the server prior to attempting the following procedures.
Failure to observe this warning could result in personal injury or damage to
equipment.
CAUTION Do not operate the server without the top cover in place. Operation of the server without the
top cover in place will result in server failure. Operation of the server without the top cover in
place will make the server susceptible to EMI problems.
Observe all ESD safety precautions before attempting this procedure. Failure to follow ESD
safety precautions could result in damage to the server.
Installing Processors
CAUTION Ensure that the cache size is identical for all processors. Failure to observe this caution will
result in system failure.
Ensure that all processors are rated for use at the same speed. Failure to observe this caution
will result in performance degradation.
