Two dip switches, S1 and S2, are located on bottom side of the drive as
shown in Figure 2 and 4.
The values of the dip switches are read only when the drive is powered
up and the values are saved in the drive's memory for later use. The
locations of each switch are as shown.

SCSI ID Switch
--------------
Dip switch S2 position 1, 2 and 3 are for setting the drive address as
shown. These are used to respond to selection or to place the device
ID on the bus during reconnection.
Note:
-----
Dip switch S2 positions 1, 2 and 3 must be set to "OFF" state when
remote address connector is used as described in remote drive address
connector setting.
SCSI Terminator Switch
----------------------
Dip switch S2 position 4 is for selecting that the SCSI active
terminator is enable or disable. "Enable" means that the on board
active terminators are connected.
Remote Drive Address Connector Setting
--------------------------------------
Drive address switch can be set remotely through the host system using
Pin 2, 3 and 4 of remote drive address connector (see Figure 2). This
address setting is enabled when the Dip Switch S2 position 1, 2 and 3
are at "OFF" position (wired ORed with Dip Switch S2 position 1, 2 and
3).
The remote drive address connector is designed to mate with molex
P/N 51021-0600 utilizing molex pin P/N 50058-8000 (AWG#28-32) or
50079-8000 (AWG#26-28). Equivalents of these part numbers are
permissible.
Pin 6 is for manufacturing test use. This pin should be open for
normal operation.

Electrical Interface Specifications
===================================
SCSI Bus Cable
--------------
External cables must not exceed 6 meters in length. The cable should
be a 50 conductor flat cable or a 25 signal twisted pair cable. The
drive conforms to the max stub length of 0.1 meter for single ended
options as specified in the ANSI SCSI standard (X3.131-1986).
Power Connectors
----------------
The DC power connector is designed to mate with AMP part number
1-480424-0 using AMP pins part number 350078-4 (strip) or 61173-4
(loose piece). Equivalents of these part numbers are permissible.
Pin numbering and assignments are shown in Figure 3 as viewed from
the direction of cable insertion.

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 Dip Switch S2 Position 4.
DC Power Requirement Limits
===========================
Power supplied to the drive must conform to the following limits:
Nominal +5 Volts (1) Total Power (2)
Tolerance +/-5% -
(include Ripple)
Ripple (0 to 20 MHz) 100mV p-p -
Supply current
(power down mode) (3) 0.2A 1.0W
(max at idle) (4) 0.86A 4.3W
(max at operation) (5) 1.5A 7.5W
Note:
-----
1. Exclude peak current less than 1 msec duration.
2. Assume that SCSI terminator power line in the host side is connected.
The actual power consumption varies depending on your SCSI
configuration and usage.
3. Power down mode is the lowest power consumption mode which is
entered when no activities, including SCSI have been done during
the time specified by SCSI MODE command of laser sleep control.
'Mode Page 21' to set laser sleep control.
4. "Idle" means waiting host command in track following. Exclude
the peak current at 1 track kickback.
5. "Max at operation" occurs during write or erase operation.
Vibration and Shock
===================
Operating Vibration
-------------------
The drive will withstand (with no permanent error) vibration levels of
0.27G RMS from 5 to 500 Hz in all three directions.
Operating Shock
---------------
The drive will withstand (with no permanent error) shock levels of 5G
half sine wave pulse (mS).
Non-operating Shock
-------------------
No damage occurs as long as the unpackaged drive is not subjected to
35 Gs, 11mS (approximate square pulse) duration.
Operating Environment
=====================
The drive operates within it's performance limits when the following
environment is maintained. Product life calculations are based on
the nominal environment for a typical application.
Humidity:
---------

Storage 5% to 95% non-condensing
Shipping 5% to 95% non-condensing
Wet Bulb Temperature:
---------------------
Operating 81 degrees F (27 degrees C) maximum
Shipping/Storage 84 degrees F (29 degrees C) maximum
Elevation:

Air Flow Volume:
----------------
Equal or greater than 0.030 cubic meter per minute (1.06 CFM) through
the drive while a media is loaded in the drive.

---------------
It is strongly recommended that drive enclosures are filtered so as to
minimize drive contamination. The air flow must be sufficient to take
account of the filter. The filter should be changed periodically to
maintain sufficient air flow.

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.
