Check all green lights on the fronts of the modules.
If all the lights are lit, installation is complete;
otherwise:
If a single light is out, power down the control
unit, reseat the module, then power up the
control unit.
If multiple lights are out, power down the
control unit, reseat the leftmost module that
has a light out, then power up the control unit.
If the lights are still out, call for support as
instructed on the inside front cover of this
guide.
Before replacing the cover, make sure all
modules are seated properly. The cover will
not fit if the modules are not seated properly.
To replace the cover, grasp it by its upper
edges and hold it squarely over the control
unit.
Place the cover over the modules and make
sure it fits firmly in place.
Tighten the screw on the lower front of the
cover.

To power down the control unit, pull out the
the main circuit breakers on both carriers or
move the on/off switch to the “off” position (“O”),
depending upon which hardware configuration
you have.
To remove the cover, loosen the screw on the
lower front of the cover. Then place one hand
on the handle on the bottom front of the cover
and place your other hand on the top of the
cover.
Gently pull the cover up and away from the
backplane—be careful not to break the tabs
that attach the cover to the backplane.
