Self-Test Indicators
The ACTIVE LED should always remain off until the HP 85105A is
accessed by the HP 8510. Each time the test set is turned on the Port 1 and
Port 2 LEDs will light for approximately 2 seconds during the self-test, and
then turn off. To determine what part of the self-test has failed, note which
LEDs on the A4 board are lit. Refer to Table 6-3 for failure indications.
If the Self-test Fails to
Run
If the portion of memory which contains the self-test programming is faulty,
the self-test will not run properly. The following conditions indicate that the
self-test ROMs are probably faulty.
•
all LEDs flash briefly and go off
•
all LEDs flash briefly and stay on
