1. Loosen the two captive screws holding the air duct over the DIMM slots, and remove the air
duct.
2. Use a screwdriver or similar tool to unhook the tool latch on the heatsink.
3. Tilt the heatsink back towards the hook latch and release the hook latch.
4. Lift the heatsink away from the processor and out of the Netserver.
5. Open the ZIF lever to allow removal of the processor.
6. Grasp the processor by its edges and lift it out of the socket and place it on a static-dissipating
work surface or into an anti-static bag.
7. If you are not replacing the processor with a new or replacement processor, you must install the
terminator into the empty processor socket.
CAUTION The empty processor socket must have a terminator installed if you are not installing
a processor into the empty socket.
8. If you intend to use the heatsink again for a new or replacement processor you must insert a
new thermal patch on the bottom of the heatsink.
Refer to the heatsink installation procedure earlier in this chapter.
CAUTION To prevent damage to the replacement processor, remove the old patch and install
a new thermal patch to the bottom of the heatsink before installing it on the new
processor.
The heatsinks are not reusable, unless the thermal patch has been replaced each
time the heatsink is removed. Each time the heatsink is used on the processor,
some of the thermal material is removed from the thermal patch, which could cause
poor heat transfer and overheating.
