Figure 1 Option Switches and SCSI Address
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- Off
up or cartridge insert.
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 honoured. Eject request received over the
library interface, or by pressing the UNLOAD button, are honoured
regardless of the setting of switch 2 (see Figure 1).
Permit Eject switch 2:
----------------------
Setting Description Default
------- ----------- -------
Off Inhibit SCSI eject request On
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.

Mating connector is BERG P/N 65051-034
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/or
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.

Electrical Interface Specifications
===================================
The IBM OEM 0632 Optical Disk Drive uses single-ended drivers and
receivers 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 part number
1-480424-0 using AMP pins part number 350078-4 or their equivalent.
Pin assignments are shown in Figure 3.

SCSI Signal Connector
---------------------
The SCSI signal connector is a 50-pin connector, Molex part number
70248 or equivalent, which meets ANSI/SCSI specifications.
SCSI Bus Terminators
--------------------
Active termination for the last device on the SCSI cable is accomplished
by setting Feature Switch 5 to the OFF Position (see below).
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.

Figure 4 Description of Optical Disk Cartridge
The optical disk drive sub-assembly uses a removable double-sided disk
that is housed in a cartridge with access to the recording surface
through a shutter mechanism. The disk is rewritable and can be
reformatted many times.

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. 130mm Rewritable Optical Disk
Cartridges for information interchange ISO/IE2 10089. 1991 (format A)
595/650MB and 1.19/1.3 GB ECMA-184.
The customer should verify the usability of non-IBM OEM brand rewritable
optical media prior to use.
Today ANSI and ISO standards for rewritable optical media are broad and
various. Manufacturers have different implementations of these
standards; as a result data stored on one manufacturers drive may not
be interchangeable with another.
Vibration and Shock
===================
Operating Vibration
-------------------
The drive will withstand (with no permanent error) vibration levels of
0.25G RMS from 0 to 500 Hz.
Operating Shock
---------------
The drive will withstand (with no permanent error) shock levels of 5G,
11mS (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, 11mS (half sine)
duration.

WARNING:
========
This disk drive can be damaged by Electro-Static Discharge; please follow
recommended ESD procedures before unpacking or handling the drive. Ask
your IBM marketing representative 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 your
IBM marketing representative if you do not have an approved shipping
container.
IBM Adstar's development and manufacturing operations are ISO 9001
certified.
