Safety Notices Listed below are the safety requirements for operating this product.
Each danger and caution notice contains a reference number (RSFTxxxx). Use the
reference number to check the translation in External Devices Translated Safety
Notices, SA26-7192.
Danger NoticesA danger notice calls attention to a situation that is potentially lethal or extremely
hazardous to people.
The following danger notices appear in this publication:
DANGER
To prevent a possible electrical shock from touching two surfaces
with different electrical grounds, use one hand, when possible, to
connect or disconnect signal cables. (RSFTD004)
DANGER
An electrical outlet that is not correctly wired could place hazardous
voltage on metal parts of the system or the products that attach to the
system. It is the customer's responsibility to ensure that the outlet is
correctly wired and grounded to prevent an electrical shock.
(RSFTD201)
Copyright IBM Corp. 1997 vii

DANGER
To prevent a possible electrical shock when adding or removing any
devices to or from the system, ensure that the power cords for those
devices are unplugged before the signal cables are connected or
disconnected. If possible, disconnect all power cords from the
existing system before you add or remove a device.
DANGER
To prevent a possible electrical shock when installing the device,
ensure that the power cord for that device is unplugged before
installing signal cables. (RSFTD204)
Caution Notices
A caution notice calls attention to a situation that is potentially hazardous to people
because of some existing condition.
The general caution symbol identifies conditions where caution must be
used.
The electrical caution symbol identifies electrical hazards where extreme
caution must be used.
The weight caution symbol indicates that the 8mm Tape Library weighs
42 kilograms (92.5 pounds). It takes three persons to safely lift the unit.
The laser caution symbol indicates a laser device is present. Handling
laser devices requires trained and knowledgeable personnel. Extreme
caution is required.
Laser Safety Cautions
The following laser safety cautions appear in this document:
CAUTION:
The bar-code reader contains a Class II laser component. Only trained service
personnel may repair the bar-code reader. (RSFTC237)
CAUTION:
Do not place a highly reflective surface between either the picker assembly
and the tape cartridge magazines or between the picker assembly and the
tape drives. This may cause damage to your eyes. (RSFTC238)
CAUTION:
If the automatic lock on the front door is not functioning and the door is
open, do not look directly at the laser beam. Staring at the beam may cause
damage to your eyes. (RSFTC239)

You accept the terms of this Agreement by your initial use of a machine that
contains IBM Licensed Internal Code (called “Code”).
These terms apply to Code used by certain machines IBM or your reseller specifies
(called “Specific Machines”). International Business Machines Corporation or one of
its subsidiaries (“IBM”) owns copyrights in Code or has the right to license Code.
IBM or a third party owns all copies of Code, including all copies made from them.
If you are the rightful possessor of a Specific Machine, IBM grants you a license to
use the Code (or any replacement IBM provides) on, or in conjunction with, only the
Specific Machine for which the Code is provided. IBM licenses the Code to only
one rightful possessor at a time.
Under each license, IBM authorizes you to do only the following:

for your use), provided you reproduce the copyright notice and any other
legend of ownership on the copy. You may use the copy only to replace the
original, when necessary; and
3. Execute and display the Code as necessary to maintain the Specific Machine.
You agree to acquire any replacement for, or additional copy of, Code directly from
IBM in accordance with IBM's standard policies and practices. You also agree to
use that Code under these terms.
You may transfer possession of the Code to another party only with the transfer of
the Specific Machine. If you do so, you must 1) destroy all your copies of the Code
that were not provided by IBM, 2) either give the other party all your IBM-provided
copies of the Code or destroy them, and 3) notify the other party of these terms.

Chapter 1. General Information
This chapter provides a brief description of the 7331 and 3449 8mm Tape Libraries
and their configuration options. The options consist of 7331 Model 305, which is
used in a RISC System 6000 environment; 3449 Model 355, used in a PC Tower
environment, and; 3449 Model 356, which is used in a PC Rack Mount
environment.

Figure 2. 8mm Tape Library
The 8mm Tape Library, provides an automated tape library solution. It can be used
as a 20-cartridge library, two 10-cartridge libraries, or as an autoloader.
The 8mm Tape Library has the following features:
The library is configured as a stand-alone tower.
An internal power supply that provides power for the tape library and the tape
drives.
One or two internally mounted tape drives.
A picker (transport mechanism) that moves tape cartridges between the
magazine slots and the tape drives.
Two removable 10-cartridge magazines, located internally above the tape
drives.
Copyright IBM Corp. 1997 1

Two bonus slots:
–One cleaning cartridge slot.
–One custom slot for either a second cleaning cartridge, drive diagnostic
cartridge, drive test cartridge, data cartridge, or special user application
cartridges.
A front door provides access to the tape magazines and tape drives. Two locks
on the door, a key lock and a software controlled lock, provide security and
safety.
An optional bar code reader for cartridge identification.
An operator control panel with an operator key pad and a graphical liquid
crystal display (LCD).
The 8mm Tape Library provides fast wide differential Small Computer System
Interface (SCSI-2), which attaches to the RISC System/6000 (RS/6000) computer,
and IBM PC Company PC Servers.
8mm Tape Library SCSI Bus Configurations
The 8mm Tape Library can be set in the following SCSI BUS configurations:
Single host system
Dual drive - dual host system
Single Host Configuration (Single or Dual Drives)
The 8mm Tape Library is configured as a single host computer system when the
tape library is attached to a single host computer system or adapter. During
random mode, in the single host configuration, the library and all tape drives are
controlled by the single adapter. During sequential mode, in the single host
configuration, all tape drives are controlled by the single adapter.
Dual Host Configuration (Dual Drive)
A dual host configuration is used when the tape library is shared between two host
computer systems. Tape Drive 1 is controlled by the host computer system
attached to the library ports 1 and 2 (accessed using connectors 1 and 2 on the
rear of the Tape Library). Tape Drive 2 is controlled by the host computer system
attached to the library ports 3 and 4 (accessed using connectors 3 and 4 on the
rear of the Tape Library).
