xii 7212 Storage Device Enclosure Service Guide

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
in 1 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:
v DDS-4, 4mm tape drive
v DAT 72, 4mm tape drive
v VXA technology tape drive
v DVD-RAM drive
v DVD-ROM drive
v Bay Blank (to be used to cover an empty bay when only one drive is installed in
the 7212 Storage Enclosure)
Figure 1 shows the 7212 Storage Enclosure with a DDS-4 4mm tape drive installed
in Bay A and a DVD-RAM drive installed in Bay B.
The 7212 Storage Enclosure has the following components on the front of the unit:
Status Lights
The following status lights are located on the left front of the enclosure:
v The Power-on light 1 is a green symbol that illuminated when the
7212 Storage Enclosure is powered on and no fault condition exists for
the enclosure.
v The fault light 2 is an amber symbol
that is illuminated when there
is a fault condition with the 7212 Storage Enclosure cooling fans.
Power
Switch
The power switch 3 is a push button switch that enables the power to be
turned on or off. Push and release the button to toggle power to the 7212
Storage Enclosure on and off.
Bay A Bay A, on the left front of the 7212 Storage Enclosure (see Figure 1), can
accommodate any one of the four storage devices or a bay blank.

Bay B Bay B, on the right front of the 7212 Storage Enclosure (see Figure 1 on
page 1), can accommodate any one of the four storage devices or a bay
blank.
The rear of the 7212 Storage Enclosure has the following components:
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.
Audio
Jack Connectors
If a DVD-ROM or DVD-RAM drive is installed in Bay B, the audio jack
connectors 3 can be used to attach the drive to a stereo amplifier.
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)
to regulate the internal temperature of the enclosure. Air exits the 7212
Storage Enclosure at the two cooling fan locations.
Note:
To ensure proper operation, place the 7212 Storage Enclosure so that
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.
Fault
Signal USB Port
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.
Notes:
1. 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.
2. Pin 2 signal voltage is dependent on the electrical design of the
monitoring receiver.
3. Pin 4 is ground.
4. Pins 1 and 3 are not connected.
Power
Cable Connector
The 7212 Storage Enclosure receives power through a cable connected to
the power cable connector 8.
Security Clip Hole
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.
System Requirement
The following sections describe the host system requirements for the 7212 Model
102 Storage Enclosure:
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.
Chapter 1. General Information 3

AS/400 and iSeries Systems
The 7212 Storage Enclosure requires only a supported AS/400 or iSeries system
processor with an OS/400 operating system at level V5R1 (or higher) and a PCI
Magnetic Media Controller (FC 2718 or FC 2768) or a PCI-X ULTRA TAPE
CONTROLLER (FC 5702) or PCI-X TAPE/DASD CONTROLLER (FC 5705). See the
