cables.
Use the following steps to install a rear module in the frame:
1. Refer to the frame Owner’s Manual, to ensure that the frame is properly installed
according to instructions.
2. On the rear of the frame, locate the card frame slot.
3. As shown in Figure 2, seat the bottom of the rear module in the seating slot at the
base of the frame’s back plane.
Figure 2. Rear Module Installation
4. Align the top hole of the RM-9231-B with the screw hole on the top edge of the
frame back plane.
5. Using a Phillips driver and the supplied screw, fasten the rear module to the frame
back plane. Do not over tighten.
All modules are installed using the same method above.
