Note: As viewed from the back of the drive, a switch is on when it is
pushed up and off when it is pushed down.
Spindle Spin-up Switch
The setting of switch 1 determines whether the spindle motor is turned on
automatically at power up when a cartridge is in the loaded position
(see Figure 1).
Spindle Spin-up switch 1:
Setting Description Default
Off Spin automatically on power up or cartridge insert Off
On No-spin-up on power-up but spin-up on cartridge
insert.
Permit Eject Switch
The setting of switch 2 determines whether an eject request received
over the SCSI interface is honored. Eject request received over the
library interface, or by pressing the UNLOAD button, are honored
regardless of the setting of switch 2 (see Figure 1).
Permit Eject switch 2:
Setting Description Default
Off Inhibit SCSI eject request Off
ON Permit SCSI eject request
SCSI Address Switch
The SCSI address of the drive is selected by using a 16-position rotary
switch. The switch is read at power up and when the drive is reset.
The drive's SCSI address (between 0 and 7) is selected by rotating the
switch to the desired location on the switch. Addresses 8 to 15 are
reserved and should not be used.

LIBRARY INTERFACE CONNECTOR
The library interface enables direct communications between a library
autochanger and the drive subassembly:
1. The autochanger controller can cause the drive to spin-down and
unload a cartridge.
2. The drive can report a busy condition to the autochanger controller.
3. The drive can report when a cartridge is ready to be picked up at
the drive cartridge entry/exit slot.
4. The autochanger controller can sense if a drive is present.
The library interface uses a pin connector on the logic board for
attachment to the (library) interface cable. This cable connects between
the drive controller and the autochanger controller card. The pin
assignments are shown in Figure 2.

that permit cable lengths of up to 6 meters (19.68 feet).
Connectors
The drive has two connectors: one for power, the other for connecting to
the SCSI bus.
Power
The DC power connector is designed to mate with AMP PN 1-480424-0 using
AMP pins PN 350078-1 or their equivalent. Pin assignments are shown
in Figure 3.

SCSI Signal Connector
The SCSI signal connector is a 50-pin connector. Molex PN 70248 or
equivalent, which meets ANSI/SCSI specifications.
SCSI Bus Terminators
Termination resistors are fitted as a standard feature on these drives.
The user can remove these if they are not required.
For a single-ended cable, a 50-conductor flat cable or a 25 twisted pair
cable can be used, with a maximum length of 6.0 meters and a stub length
not to exceed 0.1 meters.
The drive has an internal stub length of 0.077 meters. The SCSI bus
cable must not add more than 0.023 meters additional stub length to
remain compliant with ANSI.
SCSI Bus Electrical Characteristics
Note: The drive incorporates the Western Digital WD33C93A SCSI Interface
Controller and conforms to the ANSI/SCSI Interface standard.

IBM OEM 5 1/4" Rewritable Optical Cartridges have been specially developed
and tested for optimum performance when used with the IBM OEM 5 1/4"
Rewritable Optical Disk Drive. These drives are compatible with the
following ISO standard 130 mm Rewritable Optical Disk Cartridges for
information interchange ISO/IE2 10089. 1991 (format A).
The customer should verify the usability of non-IBM OEM brand rewritable
optical media prior to use.
VIBRATION AND SHOCK
Operating and Non-Operating Vibration
The drive will withstand (with no permanent damage or loss of data)
vibration levels of 0.25 G RMS from 0 to 500 Hz.
Operating Shock
The drive will withstand (with no permanent damage or loss of data)
shock levels of 5G, 11 mS (half sine) duration.
Non-Operating Shock
No damage occurs as long as the unpackaged drive is not subjected to
a square wave shock greater than a value of 35 Gs, 11 mS (half sine)
duration.
This section contains information on Troubleshooting
- The diagnostic routines test the functions of the drive and report
the results to the operator or service representative. Error details
are available to isolate error conditions between the media and drive.
The routines are:
1. Power-on self-test
2. Test at cartridge insertion
3. Send Diagnostics command test
4. Idle-time self-test
The power-on self-test (POST), with or without media, the test at
cartridge insertion, and the idle time self-test are executed automatically.
The Send Diagnostics command test routines isolate errors during
operation and at drive installation.
- The following checklist will help determine whether you have any
problems with your optical disk drive:
1. Is there power to the drive?
2. Did the POST run correctly?
3. Is the cartridge damaged?
4. Are there any visible, removable obstructions in the drive?
5. Are all cables plugged in correctly and free of damage?
6. Are the optical disk drive circuit board switches set correctly?
7. Are the optical disk drive terminators placed correctly?
- A power-on self-test (POST) is executed automatically at power-on and
when a SCSI bus RESET occurs. It is a functional test for the drive,
and it initializes the microprocessor working memory, the LSI chips,
and the drive electronics. If media (a disk) is not present at
power-on, only the POST sequence is executed.
The drive responds with CHECK CONDITION status until all the tests with
media present have completed successfully. If a disk is not present, the
drive responds to the Test Unit Ready command in 8 seconds, on average,
after power on.
If the disk is present at power on, the power-on self-test sequence and
the test at cartridge insertion are executed. These routines are
completed in 20 seconds maximum, and the drive responds with CHECK
CONDITION status until all tests have completed successfully.
If an error condition occurs, an error code is transferred through the
SCSI interface in response to the next command.
The host recognizes when the SCSI interface does not respond correctly
due to SCSI chip error.
LED Indicators (Normal Conditions)

WARNING: This disk drive can be damaged by Electro-Static Discharge,
please follow recommended ESD procedures before unpacking or handling
the drive. Ask your Dealer for details if you need assistance.
PACKAGING: The drive must be protected against Electro-Static Discharge
especially when being handled. The safest way to avoid damage is to put
the drive in an anti static bag before ESD wrist straps, etc are
removed.
Drives should only be shipped in approved containers, severe damage can
be caused to the drive if the packaging does not adequately protect
against the shock levels induced when a box is dropped. Consult the
dealer if you do not have an approved shipping container.
