Overview
The information in this document might differ from your product if it contains custom configuration
options or features.
The figures in this document are for illustration only.
Processor kit
The processor kit for an H3C UniServer R4950 G5 server includes the following components:
•
Processor
•
Heatsink
T15 and T20 Torx screwdrivers are required for processor installation. A T15 Torx screwdriver is
provided with the server. You need to prepare a T20 Torx screwdriver yourself.
Preparing for installation
WARNING
!
To
reduce the risk of personal injury from hot surfaces, allow the server and the internal system
components to cool before touching them.
CAUTION:
•
To avoid processor and system board damage, only H3C-authorized personnel and
professional server engineers can install a processor.
•
To prevent ESD damage to electronic components, wear an ESD wrist strap and wrist gloves
before beginning the installation procedure. Make sure the ESD wrist strap is reliably grounded.
To prepare the server for processor installation:
1. Back up all server data.
2. Power off the server.
3. Disconnect the power cords.
4. Remove the server from the rack.
5. Remove the access panel, as shown in Figure1-1.
a. (Optional.) If the access panel is locked, use a T15 Torx screwdriver to loosen the screw on
the locking lever, as shown by callout 1.
b. Press the release button to release the locking lever, and then lift up the locking lever as
shown by callout 2. The access panel slides towards the rear of the server automatically.
c. Lift the access panel away from the server, as shown by callout 3.

Installing the processor
CAUTION:
•
The server can use one or two processors.
•
To prevent damage to the pins on the processor socket, always install a cover over an empty
processor socket.
•Make sure all processors on a server are the same model.
To install the processor:
1. Open the processor socket. Use a T20 Torx screwdriver to loosen the screws in the sequence
shown by callouts 3 through 1 in Figure1-3. The cover of the processor socket will
automatically open.
Figure1-3 Opening the processor socket
2. Open the bracket. Hold and lift the bracket by two fingers till the bracket is fully opened, as
shown in Figure1-4.
Figure1-4 Opening the bracket
3. Remove the processor tray. Pinch the handle of the processor tray and pull the processor tray
out from the bracket as shown in Figure1-5.

4
Figure1-5 Removing the processor tray
4. Install the processor tray into the bracket. Holding the processor tray by the handle, align the
processor tray with the bracket and then insert the processor tray into the bracket as shown in
Figure1-6.

5. Remove the protective cover. Use your thumb and forefinger to lift the cover straight up, as
shown in Figure1-7.
Figure1-7 Removing the protective cover
6. Close the bracket. Slowly close the bracket and then press both corners of the open edge of
the bracket to lock the bracket.

7. Install the processor. Slowly close the protective cover of the processor cover. Then, use a
T20 Torx screwdriver to fasten the screws in the sequence shown by callouts 1 through 3 in
Figure1-9.
Figure1-9 Installing the processor
8. Remove the heatsink protective cover. As shown in Figure1-10, lift the cover straight up and
away from the heatsink.
CAUTION:
When you remove the protective cover from the heatsink, be careful not to touch the
thermal
grease on the heatsink.
Figure1-10 Removing the protective cover
9. Install the heatsink onto the server:
a. Lower down the heatsink on the processor socket as shown by callout 1 in Figure1-11.
b. Use a T20 Torx screwdriver to fasten the four captive screws on the heatsink in the
sequence shown by callouts 2 through 5 in Figure1-11.

CAUTION:
To avoid poor contact between the processor and the system board or d
amage to the pins
in the processor socket, tighten the screws to a torque value of 1.6 Nm (16.1kgf.cm).
Figure1-11 Installing the heatsink
Installing DIMMs
After you install a new processor, install DIMMs for it. For the DIMM installation guidelines, see the
server user guide.
Starting the server
1. Install the chassis air baffle on the server.
2. (Optional.) If you removed the riser card on the air baffle, reinstall it.
3. Install the access panel.
4. Install the server into the rack.
5. Connect power cords for the server.
