Configuring Models 7405 and 7429 Ethernet
LAN Controller Boards (VLC and VLCi)
When you receive an Ethernet LAN controller board from Data General
Corporation, it is factory configured for board 0 default switch/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
2–21 through 2–23 provide switch settings and jumpering information for the VLC
board. Tables 2–24 through 2–26 provide jumpering information for the VLCi board.
For example, to reconfigure a VLC board to board 1, locate the column for board 1 in
Table 2–22 or Table 2–23 and set the switches as indicated in the rectangles.
The DG/UX operating system identifies VLC controllers with the device mnemonic
hken; VLCi controllers are specified as cien devices. Make certain that no two
hken controllers have the same board number by changing the switch pack settings
on the second board. Make certain that no two cien controllers have the same board
number by changing jumper settings on the second board.
Once you have configured the proper switch or jumper settings, follow the directions
in Chapter 3 to install the board in the card cage.
