[6] SELFTESTS DURING POWER-UP
(HP 9153/54A units with S/N Prefix 2702A and Higher and the HP 9153/54B)
At power-on, a sequence of selftests checks the processor, ROM, HP-IB IC, processor RAM, buffer RAM,
and the drive(s).
The Winchester disc test reads and writes sectors, checks the spindle speed, and checks that
the ECC logic functions correctly.
The FAULT LED, if it remains on after the power-on selftest, indicates
a problem was encountered in the selftests.
l
When the HP 9153A or HP 9154A is first powered-on, the FAULT
and ON LINE LED will come on.
The
ON LINE LED goes off and the flexible disc drive ON LINE LED comes on when testing of the flexible disc
begins (9153A only).
The FAULT LED remains on until the power-on selftests are complete.
All tests are
performed in unit number order; i.e. if the address is 8 or 9, then the flexible disc drive is tested first.
If the flexible disc drive ON LINE LED goes off and the FAULT
LED remains on continuously or is flash-
ing, refer to Chapter
8, Troubleshooting and Diagnostics, for a full explanation of these error codes and
what and how to correct the fault.
NOTE
If a new
Winchester disc drive has just been installed, the
FAULT
LED will remain on until the drive has been format-
ted and the unit has been power cycled.
