The DBX is secured to the MCP-IPx or to the memory interface extension connector of
another DBX card by a threaded nylon spacer.
Preparing for Installation
1. Locate a desk or table top that will support 50 lb (23 kg). If the surface can be
damaged by sharp objects, place a protective sheet of cardboard or similar
material over the top surface.
2. Place an anti-static sheet (the card's plastic shipping bag will suffice) over the desk
or table top.
3. Remove power from the Coral IPx 500 system by turning OFF the power toggle
switch on the front panel of the PS500 unit.
4. Carefully remove the MCP-IPx card from its slot and lay it flat, over the anti-static
material.
Installing the Lower DBX
1. Remove the nylon screw from the top of the spacer associated with the memory
interface connector.
2. Carefully align the multi-pin connector on the bottom side of the DBX card with
the MCP-IPx memory interface connector.
3. Gently but firmly press the DBX connector into the MCP-IPx connector until the
DBX card rests on the nylon spacer. A slight resistance will be felt as the
connectors engage.
4. Insert the nylon screw through the mounting hole of the DBX card and thread the
screw into the nylon spacer until snug. Do not over-tighten the nylon screw or it
may be damaged.
5. Remove the plastic battery insulator tab from between the battery holder upper
contact and the lithium battery. Refer to
Figure 8-9
which illustrates the location of
the battery insulator.
Installing “upper” DBX
If the DBX is to be stacked over another DBX card:
6. Remove the screw from the top of the nylon spacer associated with the MCP-IPx
memory interface connector. This screw secures the “lower” card.
7. Thread the extension spacer provided with the DBX into the existing spacer on the
MCP-IPx.
