4. Mount the Heatsink: Place the SEC cartridge face down on a flat surface and
lay the heatsink flush on the back (metal side) of the SEC cartridge. Check the
orientation of the heatsink against the pictures below. The thicker fin must be on
the bottom. The top clamp is wider than the bottom clamp so only this orienta-
tion will fit. With a screw driver, push the clamps one at a time into the SEC
cartridge. Be sure that the heatsink is firmly pressed against the the SEC car-
tridge. When correctly installed, no light must be showing through between the
thermal pad of the heatsink and the SEC cartridge.
WARNING!
If the heatsink is not mounted tightly against the SEC cartridge,
the CPU will overheat. Be sure that sufficient air circulation is available
across the SEC cartridge’s passive heatsink. Without sufficient air circula-
tion, the SEC cartridge could overheat and damage both the SEC cartridge
and the baseboard. You may install an auxiliary fan, if necessary.

designed to fit into the SEC slot only one way. Be sure to align the notch in the
mechanism with the small rib on one side of the slot. Screw the captive nuts
(encircled) in place.
WARNING!
Do not overtighten the captive nuts. Doing so could damage your
CPU card. Tighten captive nuts to no more than 6
