Safety Notices
For a translation of the danger and caution notices contained in this book, see
Appendix B, “Translated Safety Notices”, on page 81.
Definitions of Safety Notices
Adanger notice indicates the presence of a hazard that has the potential of causing
death or serious injury.
Adanger notice appears on page 46.
Acaution notice indicates the presence of a hazard that has the potential of causing
moderate or minor personal injury.
Caution notices appear on pages 43, 45, 54, 63, 65, and 72.
An attention notice indicates an action that could cause damage to a program,
device, system, or data.
Acoustic Noise Declaration
The equivalent continuous A-weighted sound pressure level at the bystander’s
position measured for a 2104 Model DU3 or TU3 does not exceed 68 dB(A). This
level has been measured under the following conditions:
vRack-mounted unit:
–The 2104 Model DU3 had fourteen disk drive modules installed.
–The 2104 Model DU3 was installed in a 7202 Rack with the bottom of the
2104 Model DU3 system at EIA position 17.
–The remainder of the rack was filled with units to which power was not
connected.
vDeskside unit:
–The 2104 Model TU3 had fourteen disk drive modules installed.
These levels were measured using a procedure in accordance with ISO standard
DIS7779, Measurement of Airborne Noise Emitted by Computer and Business Equipment.
The equipment was installed and operated as described in Appendix C.8 of that
standard.

Electrostatic Discharge (ESD)
Attention:
When you handle field-replaceable units (FRUs) and other computer parts, take
these precautions to avoid static damage:
vLimit your movement. Movement can cause static electricity to build up
around you.
vAlways touch computer parts carefully. Hold adapters and memory-modules
by their edges. Never touch any exposed circuits.
vPrevent people who are not correctly grounded from touching computer parts.
vBefore you install a new part, touch the static-protective package that contains
the part against an unpainted metal part of the 2104 or using system for at
least two seconds. This action reduces static electricity in the package and in
your body.
vRemove the part from its package and, if possible, install it directly into the
2104 without putting the part down. If you need to put the part down, first
place the static-protective package that contained the part onto a smooth, level
surface, then place the part onto the package. Do not place the part onto any
metal surface.

Chapter 1. Using the 2104 Model DU3 or TU3
Important: The installation of this product is a customer responsibility.
Attention: Before continuing with any of the actions described in this book,
please refer to “Safety Notices”on page ix.
This section describes the Expandable Storage Plus: 2104 Models DU3 and TU3,
their controls, and how to use them. A 2104 Model DU3 or TU3 can be attached to
any supported RS/6000
™
or IBM ER s e r v e r pSeries computer that provides support
for any of the Small Computer System Interface (SCSI) adapters listed in “SCSI
Adapters and Cables”on page 77.
The 2104 Models DU3 and TU3 look like this:

2104 Model DU3
The 2104 Model DU3 is a rack-mounted SCSI disk enclosure that can be installed
into a standard Electrical Industries Association (EIA) 19-inch rack.
A fully configured 2104 Model DU3 looks like this:
Figure 2. 2104 Model DU3 from the Front (Top) and Back (Bottom)
22104 Models DU3 and TU3 Operator’s Guide

At the front of a 2104 Model DU3 there are 14 device slots 1. Each slot must
contain either a SCSI disk drive module, or a dummy disk module. Each disk
drive module connects to a backplane which is mounted vertically about halfway
between the front and back of the 2104 Model DU3.
Note: To run I/O at least one SCSI disk drive module must be present in each
2104 Model DU3.
The 14 device slots are divided into two groups of seven slots. Between the two
groups of seven slots there is a SCSI bridge card2. The SCSI bridge card assigns
the disk drive modules to a SCSI bus, in accordance with the setting of the SCSI
bus split switch on the switch card 5.
On the back of the backplane are connectors for two fan-and-power-supply
assemblies3, two SCSI interface cards4, and a switch card5.
The 2104 Model DU3 has either two fan-and-power-supply assemblies or one
fan-and-power-supply assembly and one fan assembly. Either option provides all
the necessary power and cooling for the 2104 Model DU3.
It is better, however, to have two fan-and-power-supply assemblies, rather than
one fan-and-power-supply assembly and one fan assembly, because then the
amount of power required from each power supply is reduced, and, if one power
supply fails, power for the 2104 disk enclosure continues to be supplied by the
other power supply.
The SCSI interface cards4 are used to connect host machines to the 2104 Model
DU3. These cards contain logic that provides information about what is happening
in the 2104 Model DU3 and the status of components within it.
The switch card5 contains switches that control which SCSI bus mode is selected,
how the 2104 Model DU3 is supplied with power, and what enclosure services are
enabled. It also contains a rotary switch that sets the ID of the 2104 Model DU3.
Options for configuring a 2104 Model DU3 are described in the Expandable Storage
Plus: 2104 Model DU3 Installation Guide.
