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 R4700 G5 server includes the following components:
•
Processor
•
Retaining bracket
•
Heatsink
T15 and T30 Torx screwdrivers are required for processor installation. A T15 Torx screwdriver is
provided with the server. You need to prepare a T30 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 a reliably-grounded ESD wrist strap
and a pair of ESD gloves when installing or removing the components.
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 Phillips 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.

6. Remove the chassis air baffle. As shown in Figure1-2, lift the air baffle up to remove it from the
chassis.
Figure1-2 Removing the chassis air baffle
Installing the processor
CAUTION:
•
The server can use two or four 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. Remove the heatsink protective cover. As shown in Figure1-3, lift the cover straight up and
away from the heatsink.

3
CAUTION:
When you remove the protective cover from the heatsink, be careful not to touch the
thermal
grease on the heatsink.
Figure1-3 Removing the protective cover
2. Install the retaining bracket onto the heatsink.
a. As shown in Figure1-4, align the alignment triangle on the retaining bracket with the cut-off
corner of the heatsink.
b. Lower the bracket vertically down on the heatsink until the four corners of the bracket click
into the four corners of the heatsink.
For the processor to be installed correctly, make sure the ejector lever on the retaining bracket
is closed as shown in Figure1-5.
Figure1-4 Installing the processor onto the heatsink

Figure1-5 Ejector lever status on the retaining bracket
3. Install the processor onto the retaining bracket.
CAUTION:
To avoid damage to a processor, always hold the processor by the
edges. Never touch the
gold contacts on the processor bottom.
a. Tilt the processor, align the small triangle on the processor with the alignment triangle in
the retaining bracket, and insert one edge of the processor into the retaining bracket. Place
two thumbs against the heatsink, press the other end of the processor, and lower the
processor.
Figure1-6 Installing the processor onto the retaining bracket
b. Open the clips on the retaining bracket until the processor fits snugly onto the retaining
bracket.

Figure1-7 Locking the processor
4. Remove the processor socket cover.
CAUTION:
•
Be careful not to touch the pins on the processor socket when you wear ESD gloves to
remove the processor socket cover.
•
The pins on the processor socket are very fragile. Never touch the pins. Any damage to
them might require system board replacement.
•
Keep the pins on the processor socket clean. Make sure the socket is free from dust and
any other debris.
As shown in Figure1-8, hold the cover by the tabs at both sides, and lift the cover straight up to
remove it from the socket. Keep the cover secure for future use.

Figure1-8 Removing the processor socket cover
5. Install the heatsink onto the server.
a. Align the alignment triangle on the retaining bracket with the cut-off corner of the processor
socket and the pin holes in the heatsink with the guide pins on the processor socket. Lower
down the heatsink on the processor socket. See Figure1-9.
Figure1-9 Attaching the heatsink to the processor socket
b. Press down the heatsink clips at the four corners to lock the heatsink in place.

7
Figure1-10 Locking the heatsink
c. Use a T30 Torx screwdriver to fasten the four captive screws on the heatsink.
CAUTION:
The
screwdriver torque is in the range of 6 to 12 in-lb. As a best practice, use a torque of 8
in-lb to avoid poor contact of the processor or damage to the pins on the processor socket.
Figure1-11 Fastening the captive screws

8
Installing DIMMs
After you install a new processor, install DIMMs for it. For the DIMM installation guidelines, see the
server user guide.
To install a DIMM:
1. Open the retaining clips of the DIMM slot.
Figure1-12 Opening the retaining clips of the DIMM slot
2. Align the notch on the DIMM bottom edge with the key on the DIMM slot.
3. Insert the DIMM into the slot and make sure the retaining clips lock the DIMM in place.
The DIMM slot has a structure that prevents misalignment. If you cannot insert the DIMM into
the slot easily, the installation might be wrong. Re-orient the DIMM and then insert it into the
slot again.

Figure1-13 Installing a DIMM
Starting the server
1. Install the chassis air baffle on the server. Lower down the chassis air baffle and place it into
the chassis.
Figure1-14 Installing the chassis air baffle
2. Install the access panel.
a. Place the access panel on top of the server chassis, with the guide pin in the chassis
aligned with the pin hole in the locking lever area.
b. Close the locking lever. The access panel will automatically slide toward the server front to
secure itself into place.
c. (Optional.) Lock the locking lever. Use a Phillips screwdriver to turn the screw on the lever
90 degree clockwise.
