Rear Module Installation
Each 8900PX-DR rear module requires two adjacent rear frame slots, so the
front module cannot be installed in slot 10 of the frame. Each rear module
or blank rear adapter cover is held in place by two retainer clips as shown
in
Figure 7 . To install a rear module into the frame, follow these steps:
1. Loosen (but do not remove completely) the two screws holding each
retainer clip to the frame with a 2 mm (5/64”) hex screwdriver. Pull up
on the retainer clip to remove it, leaving the screws in place.
CAUTION Be careful to leave the screws in place as they can be easily lost or fall into
equipment below the frame creating a shorting hazard.
2. Remove the blank rear adapter covers on two adjacent slots by inserting
needlenose pliers into the slots in the top and bottom of the blank and
pulling it off.
Note To remove a rear module already installed, follow the same steps. It is helpful
to first remove the front module so the rear can be pulled out more easily.
3. Insert the rear module into the empty slots.
4. Replace each retainer clip over the two screws on both sides of the
module and push down to seat the retainer.
5. Tighten the screws for each retainer clip just until they are snug. Do not
force or torque the screws too tightly.
