TABLE 2-4
Type of Test Description
Tests internal or external SCSI
test disk
disks that have a self-diagnostic
test disk0
program contained in the drive
test disk1
controller (disk0 = SCSI address
test disk2
0, disk1 = SCSI address 1, disk2
test disk3
= SCSI address 2, disk and
disk3 = SCSI address 3).
Performs a self-test diagnostic on
test cdrom
the CD-ROM drive.
Tests the SCSI tape drive by
test tape
executing the drive self-test
test tape0
program. tape and tape 0 are
test tape1
the first tape drive. tape 1 is the
second tape drive.
Outputs an alphanumeric test
test ttya
pattern on the system serial ports
test ttyb
(ttya = serial port A, ttyb =
serial port B).
Executes the keyboard self- test.
test keyboard
The four LEDs on the keyboard
should flash on once, and the
message Keyboard Present is
displayed.
Tests all of the system main
test-memory
memory if the diag-switch? is
true. If diag-switch? is set to
false, it tests the memory
according to the number specified
in selftest-#megs.
Tests all devices in the system
test-all
(such as SBus cards) that have a
built-in test program. Hard disks,
tapes, and CD-ROMs are not
tested.
Displays seconds from the
watch-clock
system's Time-of-Day chip.
Monitors broadcast Ethernet
watch-net
packets on the Ethernet cable(s)
connected to the system.
Selected FORTH Diagnostic Tests (Continued)
Preparation
The drive must be spinning
before this test is executed or
the test will fail. Enter a boot
<disk alias> command to
cause the drive to spin up.
The CD-ROM must be set to
SCSI target 6 and have a CD
inserted in the drive or the
test will fail.
Connect the tape drive to the
system and then turn on the
power.
Attach a terminal to the serial
port to observe the output.
Keyboard must be connected.
None.
Set the diag-switch?
NVRAM parameter to true.
None.
Connect the system to the
network via the desired
Ethernet port.
