CAUTION: The weight of the FPC is concentrated in the back end. Be prepared
to accept the full weight—up to 18 lb (8.2 kg)—as you slide the FPC out of the
chassis.
When the FPC is out of the chassis, do not hold it by the ejector handles, bus
bars, or edge connectors. They cannot support its weight.
