PMC Bridge Adapter and Expansion Adapter
This section provides step-by-step instructions for installing the PMC bridge
and expansion adapters onto the board computer. When the PMC bridge
adapter is installed onto the board computer, the result is a two-board assem-
bly. When both the PMC bridge and expansion adapters are installed onto
the board computer, the result is a three-board assembly.
Preliminary Requirements
Perform the following steps before installing the adapters onto your Board
Computer:
1 If the board computer is already installed in your Model 745 chassis, you
must remove it.
2 Place the board computer on a static-free mat on a clean, level surface.
PMC Bridge Adapter and Expansion Adapter Installation
1 Refer to your PMC card installation manual, and set any configuration
switches or jumpers that may be required for your application.
2 On the PMC bridge adapter board, at the sites where you will be installing
the PMC card(s), remove the two screws that secure the bezel blank(s),
and remove the blank(s). See Figure 4-3.
NOTE: When installing a PMC card, ensure that the O-ring type gasket near the bezel
remains in place.
3 Install the PMC card(s) onto the bridge adapter by aligning the front of the
card with the front bezel, and the rear of the card with the connectors and
keying pin. See Figure 4-3. There are four screws that secure the PMC
card from the bottom of the bridge adapter.
