Rear I/O Module Installation
If you are installing an openGear TM card in a 8310-C-BNC or 8310-BNC frame, skip this section.

TM
card, you will need to install the I/O
module in your 8310 frame before you can connect cables.

1. Ensure that the frame is properly installed according to instructions in the section
“Installing the Frame” of this manual.
2. On the rear of the 8310, locate the card frame slot.
3. As shown in Figure 7, seat the bottom of the DFR-RM-82xx in the seating slot at the
base of the frame’s back plane.

4. Align the top screw of the DFR-RM-82xx with the screw hole on the top edge of the
DRF-8310 back plane.
5. Using a Phillips driver and the supplied screw, fasten the DFR-RM-82xx panel to the
8310 back plane. Do not over tighten.
6. Ensure proper frame cooling and ventilation by having all rear frame slots covered
with rear I/O modules or blank metal plates. If you need blanks, see the chapter,
“Ordering Information” and contact your openGear
