Example of Running Self-Test on a SCSI Bus
To test
a group
of devices,
enter
TEST
followed
by the test number of the
first device
to
be tested and
then
the test number of the last device to
be
tested.
·
For example, entering TEST C 4 tests all tests between C and 4. Note that
you cannot select which devices to test between C and 4. All tests between
C
and 4 are tested
when
entered as
a
group. To
test all
devices, enter TEST
F
1. To repeat
a test
over and over
again
without reentering
it,
enter Repeat
TEST
x.
1.3.2 Mass Storage Controller (MSC) Module Differences
The model
30 system
supports two different
MSC
modules
(only one can
be
installed at
the
same time).
The SCSI/SCSI MSC
module
contains two
SCSI
buses (SCSI-A and SCSI-B) and the ST506/SCSI MSC module contains one
SCSI bus (SCSI-A) and one bus for the RX23 diskette drive (STRG-1). This
ST506/SCSI MSC module will be replaced by the SCSI/SCSI MSC module
once an additional adapter module is available for the RX23 diskette drive.
This adapter module interfaces the RX23 onto one of the SCSI buses on the
SCSI/SCSI
MSC
module. Until
the adapter
module is
available,
diagnostics
on the
RX23 diskette
drive are
run
through
the
STRG-1 device
by
entering
TEST
7.
1.3.3 Self-Test with Loopback Connectors
Customer
mode
self-test (that is, without any serial line
loopbacks) does
not
test
the drivers
on the
serial
lines
(DZ).
To test
the
DZ
drivers,
run
self-test
on
the serial lines in Field
Service
mode
by installing loopbacks on the two
MMJ connectors,
then
run
TEST C.
Display
the
configuration
table to see the
results.
If
only
one
MMJ loopback is available,
install
it in the
communications
port
and
run the
tests. An
error
code of 0000.0200 for the
DZ indicates
that the
printer
port does
not have the loopback installed, but
the
communications port
tested
successfully.
