4.4 Basic Acceptance Test Procedure
Perform the acceptance testing procedure listed below, after installing a
system, or whenever adding or replacing the following:
CPU module
MS690 memory module
Backplane
DSSI device
H3604 console module
1. While monitoring the test display on the console terminal, run five
error-free passes of the power-up scripts by entering the following
command:
>>>R T 0
If you cannot monitor the console terminal during this step, use the
following command.
>>>T A4
Script A4 will halt on an error so that the error message will not scroll off
the screen.
Press
CTRL/C
to terminate the scripts. Refer to Chapter 5 if failures occur.
2. Double-check the memory configuration, since test 31 can check for only
a few invalid configurations. For example, test 31 cannot report that a
memory board is missing from the configuration, since it has no way of
knowing if the board should be there or not.
