5. Execute a diagnostic test sweep.
To execute a single sweep of tests on the system, type "sweep"
and press RETURN. Slot numbers will appear on the
Diagnostics Module display in turn as each slot is tested. If a
module is present yet its slot number never appears, it may have
failed. In that case, diagnostics are not aware of its presence.
Since the proper operation of some tests depends on the
successful completion of others, possible tests will vary with the
nature of the faults encountered. For example, Line, Voice
Terminal, and Basic Telephone Modules will not be tested if a
fault is indicated in the Processor Module, because a working
processor is a prerequisite of Line, Voice Terminal, and Basic
Telephone Module tests.
The sweep of tests will last 45 seconds to 3.5 minutes,
depending on the number of modules present. The system exits
interactive mode during testing. When the prompt "DIAG
V[number]>" appears on the terminal screen, the test sweep is
complete and the system is again in interactive mode.
6. Interrupting a test sweep.
If you wish to interrupt testing and return to interactive mode,
press RETURN. (You may have to press it more than once.) The
prompt "DIAG V[number]>" will appear after the current
diagnostic test is completed. The maximum wait for a test to
complete is 30 seconds. To exit interactive mode and resume
the interrupted sweep of tests, type "resume" and press
RETURN.
7. Display test results and resolve diagnostics messages.
To display a table of faults collected during the test sweep, type
"errors" and press RETURN. For each fault recorded, the listing
indicates:
last occurrence: the test sweep in which the fault most
recently occurred.
