Determining the Board Configuration by Testing
If the board has slide switches, it maybe necessary to test the board to
determine if it has configuration
B
or
C.
If you already know the
configuration, use the test to confirm board operation.
To determine the configuration by testing:
1.
Set the switches to match configuration
B
in Figure 2-28.
2.
Install the board and close the case.
3.
Install the application software.
NOTE:
The application software has not been installed at this time.
See Chapter 3 of this guide for instructions on installing all
software.
4.
Log in as root. At the # prompt, type /vs/bin/display card
all and press (Enter).
— The following screen illustrates the data displayed when the
boards have been correctly configured. Find the O.S. Index
number. (The O.S. number is the switch [SW12.1 ] setting
for each board as seen by the system.) The system sees
Board 1 as Card 0, Board 2 as Card 1, and so on. O.S.
Indexes 0, 1, and 2 are for the first, second, and third boards
respectively.
Verify that the card number and the O.S. Index number are
the same. Also verify that the number of cards present is
equal to the number of boards installed.
