Chapter 1. General Information

The 7212 Model 102 Storage Device Enclosure is an external enclosure that
provides convenient storage expansion capabilities for select IBM eServer, pSeries,
and RS/6000 computer systems. The 7212 Storage Enclosure is designed to mount

EIA Unit (1.75″) of a standard 19-inch rack using an optional rack mount
hardware feature kit, or be configured for desktop mounting. The design of the
7212 Storage Enclosure allows for easy customer setup and installation. The 7212
Storage Enclosure has two bays that can accommodate any two of the following
storage device features:

DDS-4, 4mm tape drive

SCSI Address Switches

The Bay A 2 and Bay B 1 SCSI address switches are used to identify
the installed storage devices to the host system.

Note: The SCSI address switches are supplied as part of the device feature

kits since the various supported devices each have unique
requirements for the address switches. Therefore if no drive is
installed in a device bay, then no SCSI address switch is installed for
that bay.

RBBTV542-0

Note:

The audio jack connectors are supplied as part of the device feature
kits, since the various supported devices each have unique
requirements for the audio jack connectors. The audio jack
connectors are supplied only with the DVD-ROM Drive and the
DVD-RAM Drive feature kits. Audio jack connectors can only be
used for a DVD-ROM drive or DVD-RAM drive installed in device
bay B (see Figure 1 on page 1). If a DVD-ROM drive or DVD-RAM
drive is not installed in device bay B, no audio jack connectors are
installed in the 7212 Storage Enclosure.

Cooling Fans

The 7212 Storage Enclosure utilizes two internal cooling fans (4 and 6)

regulate the internal temperature of the enclosure. Air exits the 7212

Storage Enclosure at the two cooling fan locations.

Note:

the cooling fan exits at the rear of the enclosure and the air inlet
holes at the front of the enclosure have sufficient clearance to ensure
airflow.

SCSI Bus Connectors

The 7212 Storage Enclosure provides two, 68 pin, rear mounted, SCSI bus
connectors 5 for attaching the 7212 Storage Enclosure to the host SCSI
bus. These two external SCSI connectors represent the two ends of the
internal SCSI bus cables. The internal SCSI bus cable can be configured to
support either a single SCSI bus with one host system or with a split SCSI
bus allowing SCSI connections to two hosts. Devices installed in the two
enclosure device bays are attached to the internal SCSI bus cables so that
the installed devices can be on a single or split SCSI bus.

Note: The SCSI interface mode (Low Voltage Differential or Single Ended)

that the 7212 Storage Enclosure will operate in, is dependent on the
type of drives installed in the 7212 Storage Enclosure and the host
system SCSI adapter type.

Signal USB Port

Fault

The rear of the 7212 Storage Enclosure has a Fault Signal USB Series B Port
7. This port is provided for installations that have provisions for remote
fault monitoring of devices. If the 7212 Storage Enclosure experiences a
fault condition (power loss or fan failure) the Pin 2 signal of the USB port
will go from a high state to a low state.

Power

Security Clip Hole

System Requirement

The following sections describe the host system requirements for the 7212 Model
102 Storage Enclosure:

Notes:

The USB port pin 2 is an open collector and must be connected to a
monitoring receiver that is active for the port to have a valid output
signal.

Pin 2 signal voltage is dependent on the electrical design of the
monitoring receiver.

Pin 4 is ground.
Pins 1 and 3 are not connected.

Cable Connector

The 7212 Storage Enclosure receives power through a cable connected to
the power cable connector 8.

The 7212 Storage Enclosure can be secured to a rack or other stationary
object using a security cable and clips that are inserted into the security
clip hole 9 and then attached to a secure object. Contact your IBM
marketing representative or business partner to purchase a security cable.

RS/6000 and pSeries Systems

The 7210 Model 025 DVD-RAM Drive requires a host system platform with an AIX
operating system at level 4.3.3 with update CD LCD4-0995-14 or AIX level 5.1 with
update CD LCD4-1103-01 or higher.

For a list of supported processors and adapters, contact your IBM marketing
representative or business partner.

Media Drive Environment and Use

IBM’s goal is to provide you with a product that you can configure and use
reliably. Removable media drives require specific maintenance and environmental
conditions to operate well over time. Using high quality, data grade media,
handling and storing this media properly, operating the removable media drive in

clean environment and keeping the removable media drive properly cleaned can

help you to avoid problems with your IBM product.

Media Grades

IBM may use two different grades of media. At the discretion of IBM, Program
Transmittal Fixes (PTFs) may be supplied on media that is designed to be written

only once and read from several times. This media is not designed to be used as

backup medium.

IBM also sells media designed to be used for storage. IBM supports the media that

sell. If IBM service personnel analysis indicates a problem with non-IBM media

may be necessary for the customer to replace the media.

Media Handling and Storage

Most media is supplied in a sealed cartridge. It is provided this way so that the
media will remain in a clean environment. Opening the cartridge allows dirt and
airborne particles to enter and then become a source of contamination. The
cartridge should only be opened by the drive and not an operator. The media also

held under proper tension inside the cartridge. If the cartridge is dropped, this
tension will be relaxed. Inserting a dropped cartridge into a drive can cause
incorrect loading and result in a jam. This will ruin the media and can cause
physical damage if the cartridge is not removed properly.

When the media is stored, it must be replaced in the protective containers and
stored on the end. The storage area must be clean, dry, normal room temperature
and away from any magnetic fields.

Environmental Issues

Removable media drives are designed to operate in a clean environment. Problem
factors are dirt, dust, fibers and airborne particles. Airborne particles are the most
difficult to address. When media is installed in the drive, the clearance between the
heads and the media is measured in microns. Particles can damage the media or
the head if they come in contact with either. Customers are responsible to provide

clean operating environment for the drive and system.

Drive Cleaning

matter how clean the environment, debris may build up on the heads of any
drive. Over time, this builds up and causes errors in reading and writing.
Customers are responsible to clean the drive in accordance with the cleaning
information provided with the drive.

IBM only supports the use of IBM cleaning cartridges for IBM drives.

SCSI Hardware Issues

SCSI bus cables and terminators may affect drive performance. IBM cables and
terminators are designed specifically to keep the SCSI bus as free of noise as
possible. Use of non-IBM cables or terminators may adversely affect the SCSI bus
performance. If IBM service personnel analysis indicates a problem with non-IBM
cables, it may be necessary for the customer to replace them with the appropriate
IBM cables.

Microcode Updates

IBM constantly works to provide the best possible products. To make certain that
the drives work their very best, IBM occasionally releases changed microcode for
the drives. When a microcode change is developed, IBM makes it available to you
through the service organization or by electronic delivery.

For RS/6000 and pSeries Host Systems

Microcode changes are available from the following IBM Web site:

http://techsupport.services.ibm.com/server/mdownload

Microcode can be installed by your IBM authorized service personnel or your
system administrator.

For AS/400 and iSeries Host Systems

AS/400 and iSeries system technical support is available from the following IBM
Web site:

http://www-912.ibm.com/

Microcode can be installed by your IBM authorized service personnel or your
system administrator.

Summary

Your drive must be installed in the cleanest possible environment. Additionally,
IBM drives require high quality, data grade media and cleaning on a regular basis.
Media must also be stored and handled properly. Improper use, storage or
handling of drives or media may void your IBM warranty or service agreement

defective drive under the terms and conditions of the IBM warranty or service
agreement. It is our objective to work with you to identify the cause of any drive
problems and provide a solution.

drive stops functioning due to a component failure during the drive warranty

maintenance time, IBM will replace the drive unit. IBM will replace any
