Autochanger Error Codes
34 SCSI Interface
Controller Chip Test
Checks out operations of the SCSI interface
controller chip. This test will not be run if
initiated via SCSI, it reports PASS.
36
Motor Control Chip
Test
Exercises the registers of the motor control IC.
In order to perform correctly, this test shuts
down the servo system.
37
Drive Connect Test Checks for expected drive configuration. This is
done by polling the drive connect signal on each
of the possible drives. This line is grounded at
the drive end if a drive is connected. If the drives
physically connected do not match the expected
configuration then an error is reported.
38
Control Panel Light
Show &Button Test
Lights each portion of the display individually
and then together. Requires pushing each front
panel button to finish the test.
40
Power Supply Test Looks at both the 12-Volt and the 24-Volt power
supplies to verify that they are within limits.
The limits for the 12V supply are 11V and 13V
and the 24V supply limits are 23.5V and 25.5V.
41
SCSI Connector
Loopback Test
(Interactive)
Performs a loopback through SCSI connectors,
checking proper operation of the SCSI drivers,
receivers, and cables. Requires an external
loopback hood with terminator power. Will not
run if it was initiated via SCSI; if so, it reports
error FCH Test Did Not Run.
42
Optical Sensor Test
(Interactive if done
through the control
panel)
Checks the status of the optical sensors. Also
checks the status of the mailslot sensor (see Test
43). "0"s are placed on the control panel display
on the left and right of the display. The mark is
an open zero if the sensor is not blocked, and a
zero filled in with lit segments if a sensor is
blocked. No FRU is returned.
