Electrostatic Discharge (ESD)
Attention:
When you handle field-replaceable units (FRUs) and other computer parts, take
these precautions to avoid static damage:
v Limit your movement. Movement can cause static electricity to build up
around you.
v Always touch computer parts carefully. Hold adapters and memory-modules
by their edges. Never touch any exposed circuits.
v Prevent people who are not correctly grounded from touching computer parts.
v Before 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.
v Remove 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.

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)
2 2104 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 card2. 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
assemblies3, two SCSI interface cards4, and a switch card5.
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 cards4 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 card5 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.

Figure 12. Switch Card in a 2104 Model TU3 (Left) and 2104 Model DU3 (Right)
14 2104 Models DU3 and TU3 Operator’s Guide
Refer to Figure 13 to identify the switches on the switch card.
Figure 13. Switch Card
The switch card contains the following switches that are accessible to the operator.
Note: The ″default logical setting″ of a switch is the setting that is used if the
switch card assembly is not present when the 2104 is switched on, or when
a reset operation occurs.
Power Control switch 1
When this switch is set to Off, the 2104 automatically switches off or on
when the using system is switched off or on.
When this switch is set to On, the 2104 is powered up or down by the DC
On/Standby switch on a fan-and-power-supply assembly.
The default logical setting for this switch is On.
Drive Autostart switch 2
The disk drive motors are controlled by the combination of this switch and
the Delay Motor Start Switch 5.
When this switch is set to On, and the Delay Motor Start Switch 5 is set
to Off, the disk drive motors do not start until a START MOTOR command
is issued. The timing sequence of disk motor startup is under the control of
the using system software.
When this switch is set to Off, and the Delay Motor Start Switch 5 is set
to On, the disk drives are set to Delay Motor Start mode. The disk motor
startup delay time is different for each disk drive and is usually computed
Chapter 1. Using the 2104 Model DU3 or TU3 15
by multiplying 12 seconds by its SCSI ID. For example, the disk drive
motor of a disk drive having a SCSI ID equal to two will start 24 (2 x 12)
seconds after power is applied to the 2104.
When this switch is set to Off, and the Delay Motor Start Switch 5 is set
to Off, the disk drives are set to Normal Start mode. The disk drive motors
will start when power is applied to the 2104.
The effect of both this switch and the Delay Motor Start Switch 5 being
set to On is undefined.
The default logical setting for this switch is On.
Enable Enclosure Services switch 3
When this switch is set to On, the enclosure services can operate.
When the switch is to Off, no response occurs to any request to use the
enclosure services.
The default logical setting for this switch is On.
Select Enclosure Services switch 4
This switch selects which enclosure services can be used — SAF-TE or SES.
When set to Off, it selects SAF-TE.
When set to On, it selects SES.
The default logical setting for this switch is On.
Note: SAF-TE services are not used with RS/6000 or IBM Eserver pSeries
computers.
Delay Motor Start switch 5
Refer to the explanation of the Drive Autostart Switch 2.
The default logical setting for this switch is Off.
Box ID switch 6
This 10-position rotary switch indicates the ID of the 2104. The operator
selects the required setting which can be used by the SES Inquiry
command and the SAF-TE buffer 1 command.
The default logical setting for this switch is 0.
Note: SAF-TE services are not used with RS/6000 or IBM Eserver pSeries
computers.
The switch card has other switches that are accessible only when the switch card is
removed from the 2104. They should only be changed when the 2104 is being
converted from a Model DU3 to a Model TU3, or from a Model TU3 to a Model
DU3.
SCSI Address switch 7
When this switch is set to Off, which is its default setting in a 2104 Model
DU3, the SCSI addresses of the disk drives are 0, 1, 2, 3, 4, 5, 6, 8, 9, 10, 11,
12, 13, 14, from left to right. When the switch is set to On, these addresses
are reversed.
Note: This setting, On, is not supported in a 2104 Model TU3 or 2104
16 2104 Models DU3 and TU3 Operator’s Guide
Model DU3.
Orientation switch 8
This switch should be set to Off in a 2104 Model DU3, and to On in a 2104
Model TU3. Its setting determines the position of the Power and Check
lights on the 2104.
SCSI Bus Split switch 9
This switch controls the SCSI bus configuration. When the switch is set to
Off, the 2104 is configured as a single SCSI bus. When the switch is set to
On, the 2104 is configured as a dual (or split) SCSI bus. In a 2104 Model
DU3, with this switch set to On and the SCSI address switch set to Off, the
SCSI addresses of the disk drives are 0, 1, 2, 3, 4, 5, 6, from left to center,
on one SCSI bus, and 8, 9, 10, 11, 12, 13, 14, from center to right, on the
other SCSI bus.
The default logical setting for this switch is Off.
Reserved 10
This switch should be set to Off.

Identifying 2104 Disk Enclosures
The Box ID switch on the switch card is a 10-position rotary switch that indicates
the ID of the 2104. Its setting is used by the SES Inquiry command or the SAF-TE
buffer 1 command.
Labels are supplied with the 2104 to enable the operator to identify each 2104. It is
recommended that the label that represents the ID set by the Box ID switch is
attached to the front of the 2104.
18 2104 Models DU3 and TU3 Operator’s Guide
Identifying Disk Drive Modules
You can identify a disk drive module by the serial number that appears on a label
1 on the front of the module:
Figure 14. Disk Drive Module Label
This label also shows the size of the disk drive.
Each disk drive module also has a SCSI address that is related to its position in the
2104.
The addresses used are 0, 1, 2, 3, 4, 5, 6, 8, 9, 10, 11, 12, 13 and 14. These addresses
are usually assigned, in sequence, from left to right in the 2104 Model DU3 and
from top to bottom in the 2104 Model TU3.

Security
On the 2104 Model TU3, a lock 1 on the front cover provides physical security
for the disk drives. You do not need to remove this cover during normal
operations. If you lock the cover, it cannot be opened for servicing without the use
of the key. You do not need to lock the cover for it to stay closed. The 2104 Model
DU3 has no cover or lock.

Chapter 2. Adding Disk Drive Modules
This chapter describes how to add disk drive modules to a 2104 that is already
installed as part of your system.
You can do this only if:
1. You are authorized by your organization.
2. You have the correct disk drive module. Refer to Figure 17. This disk drive
module has, at the front, a handle 1 that can be pulled upward to open. The
disk drive module should also be the correct size. The size of a disk drive
module is shown on a label 2 at the front of the disk drive module. The label
is shown in more detail in Figure 14 on page 19.
Figure 17. Disk Drive Module Handle and Label
Attention:
v Disk drive modules are fragile. Handle them with care. Keep them well away
from strong magnetic fields.
v Any slot that has no disk drive module installed must contain a dummy disk
drive module. The dummy module ensures that the correct airflow is
maintained around the disk drive modules in the other slots. If a slot remains
empty, overheating might occur.
You do not need to remove power from the 2104 when adding a disk drive
module.
After you have added a disk drive module to a 2104, you must add it into your
system software configuration by using the system programs. Refer to Appendix A,
“Operating with RISC Systems”, on page 77.
23
Before Adding a Disk Drive Module
1. Identify the slot for the new disk drive module by using the configuration
planning information for your system. A dummy disk drive module should be
in the slot. Refer to Figure 18.
Figure 18. Dummy Disk Drive Module
Use the SCSI Device Identification and Removal service aid to set the disk
drive slot to Insert. If you then remove the dummy disk drive module from the
identified slot, an amber light on the backplane should be visible. This verifies
that you have selected the correct slot into which to add the new disk drive
module. This light goes off when a disk drive module is added. If it does not, it
is visible as the amber Check light on the disk drive module that you have
added.
