and might have a protective cover over the microprocessor. Do not use the tool
or remove the cover from the microprocessor until you are instructed to do so.
1. Read the safety information and installation guidelines, see "Safety" on page
vii and "Installation guidelines" on page 45.
2. Turn off the server (see "Turning off the server" on page 41) and all attached
peripheral devices. Disconnect all power cords; then, disconnect all external
cables as necessary to replace the device.
3. Remove the DDR3 compute book from the server.
4. Remove the DDR3 compute book cover (see "Removing the DDR3 compute
book cover" on page 218).
5. Remove the heat sinks:
a. Use a screwdriver to loosen the captive screw on one side of the heat sink
to break the seal with the microprocessor.
b. Loosen all the captive screws on the heat sink, rotating each screw one full
turn until each screw is loose.
c. Gently lift the heat sink from the microprocessor.
