Overview
The following information is for generic reference. Plan your installation and removal procedures depending on the actual requirements.
The figures in this document are for illustration only.
Processor kit
The processor kit for an H3C UniServer R4700 G3 server includes the following components:
· Processor
· Retaining bracket
· Heatsink
· Fan
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.
The figures in this document are for illustration only.
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 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 down the server.
3. Disconnect the power cords.
4. Remove the server from the rack.
5. Remove the access panel.
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 in Figure 1.
b. Press the latch on the locking lever and lift up the locking lever as shown by callouts 2 and 3 in Figure 1. The access panel slides towards the rear of the server automatically.
c. Hold the two sides of the access panel and lift it away from the server, as shown by callout 4 in Figure 1.

6. Remove the chassis air baffle. As shown in Figure 2, lift the chassis air baffle up and away from the chassis.

Installing the processor

|
CAUTION: · 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 avoid damage to a processor, always hold the processor by the edges. Never touch the gold contacts on the processor bottom. |
To install the processor:
1. Install the processor onto the retaining bracket.
a. As shown by callout 1 in Figure 3, line up the small triangle on the processor with the alignment triangle molded into the retaining bracket, and align the guide pin on the bracket with the notch on the processor.
b. As shown by callout 2 in Figure 3, lower the processor gently and make sure the guide pins on the opposite side of the bracket fit snugly into notches on the processor.

2. Install the retaining bracket onto the heatsink.

|
CAUTION: When you remove the protective cover from the heatsink, be careful not to touch the thermal grease on the heatsink. |
a. Remove the heatsink protective cover. As shown in Figure 4, lift the cover straight up and away from the heatsink.
Figure 4 Removing the protective cover
b. Install the retaining bracket onto the heatsink. The heatsink has a corner cut off. As shown in Figure 5, align the alignment triangle on the retaining bracket with this corner of the heatsink. Lower the bracket vertically down on the heatsink until the four corners of the bracket click into the four corners of the heatsink.

3. 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. |
Hole the cover by the notches on the two sides and lift the cover straight up and away from the socket. Keep the cover secure for future use.

4. 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 callout 1 in Figure 7.
b. Fasten the captive screws on the heatsink in the same sequence as shown by callouts 2 to 5 in Figure 7.

(Optional) Installing fans
Figure 8 Fan slot numbering
Guidelines
The server supports N+1 fan redundancy.
Follow these guidelines to configure fans for the server:
· Fan slots 4 to 7 each must have a fan installed.
· Fan slots 1 to 3 each must have a fan installed if one of the following conditions is met:
¡ The server uses two processors.
¡ The server uses one processor and is configured with GPUs, NVMe SSDs, or drives at the rear.
· Install fan blanks in fan slots 1 to 3 when they do not have fans installed.
Installing a fan
1. Remove the fan blank from the fan slot. As shown in Figure 9, lift the fan blank up and away from the fan slot.
Figure 9 Removing the fan blank from the fan slot
2. Install the fan. As shown in Figure 10, holding the fan by the part above the fan connector, align the two pin holes on the fan with the guide pins on the chassis. Lower the fan down into the slot. The fan connector is automatically inserted into the fan connector on the system board.
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.
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 slips 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 chassis air baffle on the server.
2. Install the access panel.
3. Install the server into the rack.
4. Connect power cords for the server.
5. Power on the server.
