all other jumpers are factory-configured, as indicated.
Configuring a Model 7416 VME Token Ring
When you receive a VTRC board from Data General Corporation, it is factory
configured for board 0 default jumper settings and for DG/UX revision 5.4.1 or
earlier. 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 2–27 through 2–29
provide jumper settings for the VTRC board. For example, to reconfigure a VTRC
board to board 1, locate the column for board 1 in Table 2–28 or 2–29 and set the
jumpers as indicated in the rectangles.
NOTE:
If your configuration includes more than one Token Ring LAN controller
board, make sure that no two boards have the same board number. The
DG/UX operating system can then distinguish between vitr(0), vitr(1),
etc. as it refers to the VTRC boards.
Figure 2–18 shows the location of the jumpers and their settings on the VTRC board.
For further information on the VTRC, refer to Configuring the VME Token Ring
Controller (VTRC) for AViiON Systems.
NOTE:
Verify that the VME controller you plan to install is jumpered
appropriately for the current revision of your DG/UX operating system.
Once you have positioned the proper jumper settings, follow the directions in
Chapter 3 to install the VTRC board in the card cage.
NOTE:
To prepare and install a token-ring LAN, TAUs, MAUs, and network
hardware, see DG/Token Ring Local Area Network Installation Guide.
