7.4.3—Installation
The modules slide into card guides in the control's chassis and plug into the
motherboard. The modules are held in place by two screws, one at the top and
one at the bottom of the front panel. Also at the top and bottom of the module are
two handles which, when toggled (pushed outward), move the modules out just
far enough for the boards to disengage the motherboard connectors.
