Procedure
1 If this PMC card is being installed in a system that is already in use, before
shutting down the operating system, log in as superuser or root and enter
the following command in a terminal window:
rm /dev/crt*
2 Stop any application programs, then shut down your system.
3 Turn the system off, and unplug the power cord(s) and all other cables to
the SBC.
WARNING:
To avoid electrical shock, make sure you unplug the power cable from the wall
outlet and the system unit before proceeding any further.
4 Using a flat-tipped screwdriver, unscrew the captive screws that secure
the board computer in the card cage.
5 Use the ejector handles to eject the board, and pull the board computer as-
sembly out of the card cage.
6 Decide which PMC site you will install the card into, and remove the
PMC bridge and expansion adapter (if present) from the Model 744 SBC.
7 On the PMC bridge adapter or expansion board, at the site where you will
be installing the PMC card, remove the two screws that secure the bezel
blank, and remove the blank. See Figure 1 and Figure 2.
NOTE:
When installing a PMC card, ensure that the O-ring type gasket near the bezel
remains in place.
8 Install the PMC card onto the 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 1 or Figure 2. There are four screws that secure the PMC card
from the bottom of the adapter (use the screws included with the kit).
