Configuring a Model 7430 VME SCSI-2
Adapter (VSA) Board
When you receive a VSA 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. Tables 2–19 through 2–20 provide jumpering information for the VSA board.
For example, to reconfigure a VSA board to board 1, locate the column for board 1 in
Table 2–20 and remove or install the jumpers as indicated in the rectangles.
NOTE:
If your configuration includes more than one VSA board, make certain
their jumper configurations specify a different board number for each. The
DG/UX operating system recognizes all VSA options by the same device
name, dgsc.
Figure 2–12 shows the location of the jumpers on the VSA board. For information on
how to position the VSA’s two daughter boards for single-ended or differential SCSI
operation, refer to the later section Selecting Single–Ended or Differential SCSI Bus
Operation.
