Overview
This guide provides a brief introduction to processor installation on an H3C UniServer R6900 G3
server.
The preparations required before installing a processor might differ from your products.
The figures in this document are for illustration only.
Processor kit
The processor kit for an H3C UniServer R6900 G3 server includes the following components:
•Processor
•Retaining bracket
•Heatsink
AT30 Torx electric screwdriver is required for processor installation. Prepare one yourself.
Preparing for installation
WARNING!
To avoid bodily injury from hot surfaces, allow the server and its internal components to cool before
touching them.
CAUTION:
•To avoid damage to the processors or system board, only H3C-authorized personnel and
professional server engineers are allowed to install a processor.
•To avoid ESD damage, put on an ESD wrist strap before installing a processor, and make sure
the wrist strap is reliably grounded.
To prepare for processor installation:
1. Back up all server data.
2. Power down the server.
3. Disconnect the power cords.
4. (Optional.) Remove the security bezel, if any, from the server.
5. Remove the CMOD.
a. As shown in Figure 1, press the release buttons on the two sides of the CMOD towards
each other so that the locking levers project from the CMOD front panel.

2
Figure 1 Releasing the CMOD
b. As shown by callout 1 in Figure 2, press forward the locking levers to disengage the CMOD
from the server. Then pull the CMOD out of the server, as shown by callout 2 in Figure 2.
Figure 2 Removing a CMOD
6. Remove the CMOD access panel.
a. As shown by callout 1 in Figure 3, simultaneously press the two release buttons on the
access panel and slide the access panel a little towards the rear.
b. As shown by callout 2 in Figure 3, lift the access panel away from the CMOD.

7. Lift the air baffles away from the CMOD, as shown in Figure 4.
The removal procedure is the same for air baffles. The following figure removes two air baffles.

CMOD and processor numbering
CMOD numbering
An R6900 G3 server supports two CMODs.

Processor numbering on CMODs
A CMOD supports two processors. The two processors on each CMOD are numbered P2 and P1
from left to right.

Guidelines
Follow these guidelines to install processors on an R6900 server:
•Make sure all processors on a server are the same model
•You can install one, two, or four processors on a server. The processor installation positions
vary by the number of processors installed on the server.

Procedure
CAUTION:
To prevent damage to the pins on the processor socket, always install a cover over an empty
processor socket.
To install the processor:
1. 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. As shown by callout 1 in Figure 7,line up the small triangle on the processor with the
alignment triangle molded into the retaining bracket, and fit the tab on the bracket into the
notch on the processor.
b. As shown by callout 2 in Figure 7,lower the processor gently onto the bracket. Make sure
the tabs on the opposite side of the bracket fit snugly into notches on the processor.

Figure 7 Installing the processor onto the retaining bracket
2. Install the retaining bracket onto the heatsink.
CAUTION:
When you remove the protective cover from a heatsink, be careful not to touch the thermal
grease on the heatsink.
a. Lift the cover straight up and away from the heatsink, as shown in Figure 8.

7
Figure 8 Removing the protective cover from the heatsink
b. Install the retaining bracket onto the heatsink. As shown in Figure 9, align the alignment
triangle on the retaining bracket with the cut-off corner of the heatsink. Place the bracket on
top of the heatsink, with the four corners of the bracket clicked into the four corners of the
heatsink.
Figure 9 Installing the processor onto the heatsink
3. Remove the processor socket cover.

CAUTION:
•Take adequate ESD preventive measures when you remove the processor socket cover.
•Be careful not to touch the pins on the processor socket, which are very fragile. Damage to
pins will incur system board replacement.
•Keep the pins on the processor socket clean. Make sure the socket is free from dust and
any other debris.
Hold the cover by the finger cutouts on its two edges and lift it straight up and away from the
socket. Keep the cover secure for future use.
Figure 10 Removing the processor socket cover
4. Install the heatsink onto the server.
a. As shown by callout 1 in Figure 11, 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 of the processor socket. Lower down the heatsink onto the processor socket.
b. Fasten the captive screws on the heatsink in the sequence as shown by callouts 2 to 5
in Figure 11. The screws might fall off if you do not follow this sequence.
CAUTION:
To avoid poor contact or damage to the socket pins, fasten the screws to a torque of 1.4
Nm (12 in-lbs).
Figure 11 Attaching the heatsink to the processor socket

Installing DIMMs
After you install a new processor, install DIMMs for it. See "DIMM configuration" on the label on the
CMOD access panel.
To install a DIMM:
1. Open 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. Reorient the DIMM and then insert it into the
slot again.

Starting the server
1. Install the removed air baffles.
2. Install the access panel for the CMOD.
3. Install the CMOD on the server.
4. (Optional.) If the security bezel is removed, reinstall it.
5. Connect power cords for the server.
6. Power on the server.
