Caution Caution
All electronic computer components are sensitive to static electricity. Always take
antistatic precautions before handling such components (see the Appendix for more
details). An earthing stud is provided at the rear of the server.
To remove the existing processor
1. If the system was in use just before starting this procedure, the processor
will be hot , wait at least 15 minutes for it to cool down.
2. If there is no processor fan, a strong spring clip secures the large
heatsink to the processor. Release the end of the spring from the hook
on the front of the ZIF socket with care and slide the heatsink clear.
Handle carefully as there may be heat transfer compound on the
heatsink face.
◊
There may be a power lead for a fan if the processor has one fitted
in the place of a simple heatsink. Take note of the fan power lead
polarity before releasing it from its board connection.

4. Lift the processor out of the socket and place it on an anti-static surface
outside the system unit. Hold the processor by its edges and avoid
touching any of the metal pins.
Warning Warning
If the processor does not easily lift out of, or fit into the socket, do not force it or
damage may be caused to the processor and the socket. Consult your supplier or an
Apricot dealer.
To fit the upgrade processor
Complete kits of Processor, Spring clip, Heatsink and Voltage Regulator
Module (VRM8) are available from your Apricot dealer.
1. Ensure that the securing lever on the ZIF socket is still in the upright
position.

They must all be of the same speed and type.
2. Take the upgrade processor out of its anti-static packaging. Hold the
processor by its edges and avoid touching the metal pins. The processor
