TROUBLESHOOTING AND DIAGNOSTICS
THE SS/80 EXERCISER
The SS/80 Exerciser provides some capabilities that are not available otherwise, and also provides more in-
formation about the HP 9153/54 A&B than is otherwise available.
Specifically, the Exerciser provides the
capability to transfer data and commands between a host computer and the peripheral, as well as perform-
ing certain tests which cannot be implemented in any other way.
Please refer to the SS/80 Exerciser manual, P/N 5958-4142
for an overview of the capabilities contained
in the Exerciser.
Some general testing solutions which can be implemented using the Exerciser are as follows:
HP-IB channel test
Testing for R/W
errors
General product
evaluation
Flexible disc
tests
Complete product
evaluation
The LOOPBAK
test in the SERVC module tests the capability to com-
municate with the product across the HP-IB.
The R/W__TEST
module
allows either a Read Only, or a Write then
Read test to be performed on a single unit.
This test can be set to loop
up to 32,000 times and allows extensive testing to identify a problem or
verify a repair.
The
R/W__TEST
module
provides
capability
to
perform
general
product testing and is recommended for this use.
The
SERVC
module
contains
special flexible
disc drive
tests-motor
speed, Track 0, Head cleaning routine, etc.
The OPER
program provides the capability to test all units and volumes
of a disc drive without manually selecting each one.
An OPER program
can be defined which
will select each unit and volume and then per-
form a locate and verify, locate and read, locate and write, etc.
The
program will allow looping to perform extensive testing.
If the drives are removed or replaced, refer to Figure 8-6 for the proper setting of the drive select switch.
