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 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.
