Configuring a Model 7431 VME FDDI
Controller (VFC) Board
When you receive a VFC board from Data General Corporation, it is factory
configured for board 0 default jumper settings. If the board you are installing is not
the first of its type, you must reconfigure the board for the position that it is to
occupy. Table 2–31 provides jumpering information for the VFC board. For example,
to reconfigure a VFC board to board 1, locate the column for board 1 in Table 2–31
and set the jumpers as indicated in the rectangles.
NOTE: If your configuration includes more than one VFC board, make sure that
no two boards have the same board number. The DG/UX operating system
recognizes all VFC options by the device name pefn.
Figure 2–19 shows the location of the jumpers and their settings on the VFC board.
For further information on the VFC, refer to the VMEbus FDDI Controller (VFC)
User’s Guide.
NOTE: Verify that the current revision of your DG/UX operating system is suitable
for the VME controller you plan to install.
Once you have installed the board jumpers, follow the directions in Chapter 3 to
install the VFC board(s) into the card cage.
