•
Processors of the same model support two types of heatsinks: one with sparse fins and one
with dense fins. For the blade server, processor 1 and processor 2 must use heatsinks with
dense fins labeled with
Rear . For more information about the position of processors, see
system board layout in "Appendix A Server specifications."
•
For the server to operate correctly, make sure processor 1 is in position. For more information
about processor locations, see system board layout in "Appendix A Server specifications."
•
The pins in the processor sockets are very fragile and prone to damage. Install a protective
cover if a processor socket is empty.
•
You must paste the barcode label shipped with the processor to the side of the heatsink to cover
the original barcode label on the heatsink. This ensures that H3C will provide the warranty
service for the processor.
Prerequisites
Take the following ESD prevention measures:
•
Wear antistatic clothing.
•
Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
•
Do not wear any conductive objects, such as jewelry or watches.
Before replacing, make sure that you back up the data, stop all services, and power off the blade
server. For more information, see "
Powering off the blade server ."
Remove the blade server. For more information, see " Removing the blade server ."
When you replace a component, examine the slot and connector for damages. Make sure the pins
are not damaged (bent for example) and do not contain any foreign objects.
You might also remove other components. For the removed components to be reinstalled correctly,
record their positions and connections before removal, for example, taking pictures of cable
connection and drive installation positions, or labeling cables.
Removing a processor
1. Remove the access panel. Press the unlock button on the access panel, slide the panel to the
server rear, and lift the access panel.
2. Remove the air baffle that hinders you operation.
3. Remove the heatsink.
CAUTION:
The pins in the processor socket are fragile and prone to damage. To avoid damage to the
system board, do not touch the pins.
Tighten the screws to a torque value of 1.4 Nm (12 in-lbs), loosen the captive screws on the
heatsink in the sequence of 4 to 1 as labeled, and lift the heatsink.
4. Remove the retaining bracket that carries the processor.
a. Identify the TIM BREAKER sign on the bracket, and use a flat-head screwdriver to lever up
the bracket from the notch next to the sign.
b. Release the four corner clips of the retaining bracket. Open two clips from the outside and
pinch the rest two clips in the notches.
c. Lift the retaining bracket.
