6 2104 Models DU3 and TU3 Hardware Technical Information
SCSI Interface Cards
Attached to the back of the backplane in a fully configured 2104 Model DU3 or 2104
Model TU3 are two SCSI interface cards. Both cards can be used to connect host
machines to the 2104 disk enclosure. A SCSI interface card provides the following
functions:
v Supports SCSI Enclosure Services at the SCSI node at address 15 on the external
SCSI bus
v Reads the Vital Product Data (VPD) for the backplane, the fan-and-power-supply
assembly, the fan assembly, the switch card, the SCSI interface card, and the SCSI
bus bridge card
v Inputs the fan-and-power-supply assembly fault lines
v Controls the fan-and-power-supply assembly fault LEDs and the fan assembly fault
LED
v Controls the fault LED at the front of the 2104 Model DU3 or 2104 Model TU3
v Monitors the EPOW (Early Power-Off Warning) signal from the power supplies, and
passes this information to the disks when needed
v Supports hot plugging of disk drive modules
v Detects and indicates faults within itself
v Supports LVD (low-voltage differential) Ultra3 SCSI (160MB per second data rate)
Note: Single-ended (SE) SCSI is not supported.
The other SCSI interface card detects and indicates only faults within itself. However, if
the first SCSI interface card fails, the second SCSI interface card provides all the
functions previously provided by the other SCSI interface card.
If the 2104 contains only one SCSI interface card, the SCSI interface card provides all
the functions listed above.
Chapter 1. Introduction 7
Fan-and-Power-Supply Assemblies
Attached to the back of the backplane in a fully configured 2104 Model DU3 or 2104
Model TU3 are two fan-and-power-supply assemblies.
Each fan-and-power-supply assembly provides enough power for the 2104, so it is
possible for there to be just one fan-and-power-supply assembly in a 2104. The second
fan-and-power-supply assembly is replaced by a fan assembly. The
fan-and-power-supply assembly provides the power for the fan assembly via the 2104
backplane.
8 2104 Models DU3 and TU3 Hardware Technical Information
Switch Card
Attached to the back of the backplane in a fully configured 2104 Model DU3 or 2104
Model TU3, the switch card contains switches that control some of the functions of the
2104.
Switches that are accessible from the back of the 2104 are provided to indicate:
v Whether power to the 2104 is turned on or off automatically when the host computer
is switched on or off
v Whether the disk drive modules are started automatically when power to the 2104 is
turned on
v Whether the disk drive modules are all started simultaneously or sequentially
v Whether enclosure services can operate
v Which enclosure services, ANSI SCSI-3 Enclosure Services (SES) or Conner/Intel
SCSI-accessed Fault-tolerant Enclosures (SAF-TE), can operate
v The ID of the 2104
Switches that are accessible only when the switch card has been removed from the
2104 are provided to indicate:
v That the order of the SCSI addresses is reversed
v Whether the setting of the LEDs is for a rack-mounted unit or for a deskside unit
v Whether the 2104 is configured as single SCSI bus mode or dual SCSI bus mode
Chapter 1. Introduction 9
SCSI Bus Bridge Card
Located centrally in the front of a 2104 Model DU3 or 2104 Model TU3, the SCSI bus
bridge card controls the SCSI bus configuration of the 2104. It assigns the disk drive
modules to a SCSI bus, in accordance with the setting of the SCSI bus split switch on
the switch card.
SCSI Bus Configurations
There are three valid configurations :
v Single bus, one initiator (SCSI ID 7), 14 disk drive modules (SCSI IDs 0 through 6,
and 8 through 14)

Notes:
1. The recommended operating temperature is 22°C (72°F) or lower. At lower
temperatures, the risk of failure in the unit is reduced. If the operating temperature
is above 22°C (72°F) for long periods of time, the 2104 is exposed to a greater risk
of failure from external causes.
2. The nonoperating environment must not exceed the operating environment limits for
longer than 60 days.
3. The storage environment must not exceed the operating environment limits for
longer than 1 year.
4. Substantial deviations from the recommended operating range, in either direction, if
sustained for extended periods of time, will expose the 2104 to greater risk of failure
from external causes.
Altitude
Altitude (from sea level) limits for both models are:
Operating: 0 to 2133 m (0 to 7000 ft)
Nonoperating: −304.8 m to 12 192 m (−1000 to 40 000 ft)
Note: The upper dry bulb temperature limit of the rack-mounted unit is lowered by 1°C
(2°F) for every 137 meters (450 feet) above 915 meters (3000 feet). The upper
wet bulb temperature limit is lowered by 1°C (2°F) for every 274 meters (900
feet) above 305 meters (1000 feet).
14 2104 Models DU3 and TU3 Hardware Technical Information
Heat Output, Airflow, and Cooling
The maximum heat output of either model is 330 watts (1126 BTU/hr).
Each 2104 requires an airflow of 1.1 m³ ( 40 cubic feet) per minute.
When racks containing many 2104s are to be installed together, the following
requirements must be met to ensure that the 2104s are adequately cooled:
v The airflow is in at the front of the rack and out at the back. To avoid moving exhaust
air to the intake of another piece of equipment, racks should be positioned in
alternate rows, back-to-back and front-to-front.
v The front of racks should be positioned on floor-tile seams, with a full line of
perforated tiles immediately in front of the racks.
v Where racks are in rows front-to-front or back-to-back, there should be a gap of at
least 1220 mm (48 in) separating the rows.
v To ensure proper airflow within each rack, the rack filler plates must be installed in
unused positions. Also, all the gaps in the front of the racks must be sealed,
including the gaps between the 2104s.
Chapter 2. Product Characteristics 15
Electrical Power
Electrical power is supplied to each 2104 by either one or two fan-and-power-supply
assemblies. These fan-and-power-supply assemblies convert the input voltage to dc for
distribution within the 2104.
One fan-and-power-supply assembly provides enough power for a fully populated 2104.
If two fan-and-power-supply assemblies are present in the 2104, each disk drive
module receives power from both fan-and-power-supply assemblies. If one
fan-and-power-supply assembly fails, all disk drive modules can continue to operate.
Input-voltage Requirements
Main AC Supply
Fan-and-power-supply assemblies can run uninterrupted with ac inputs from 90 to 260
volts and from 47 to 63 Hz.
The 2104 is designed to operate within the limits of power line disturbance given in the
table below.
Transient Voltage
(rms)
Duration Frequency Nominal Voltage (rms)
287 V 2.0 s 47 to 63 Hz 240 V
70 V 2.0 s 47 to 63 Hz 100 V
65 V 0.5 s 47 to 63 Hz 100 V
0 V 20 ms – 100 V
–48 Volts DC Supply
For Model DU3 units with the optional –48 V power supply feature, the input voltage
must be in the range –40Vto–60 V.
The 2104 is designed to operate within the limits of power line disturbance given in the
table below.

second)
Two power supplies (100
disk ops per second)
100 VAC input 410 W 210 W each
240 VAC input 430 W 220 W each
Power Factor
Power factor correction is applied within the fan-and-power-supply assemblies of each
2104. This maintains the power factor of the unit at not less than 0.95 at 50% of
maximum load.
Output Protection
Each fan-and-power-supply assembly has over-current and over-voltage protection.
Early Power-Off Warning (EPOW)
Each fan-and-power-supply assembly provides an early power-off warning (EPOW)
signal to the controlling SCSI interface card. When both fan-and-power-supply
assemblies signal an EPOW, the controlling SCSI interface card signals an EPOW to
each disk drive within the 2104.
Chapter 2. Product Characteristics 17
Power Control
Each fan-and-power-supply assembly in the 2104 has a DC On/Standby switch.
The power to the 2104 is also controlled by the Power Control switch on the switch
card.
Power Sequencing
The power sequencing of the disk drive modules in a 2104 is controlled by the settings
of the Drive Auto-Start and Select Enclosure Services switches on the switch card.
These are:
Drive Auto-Start switch Select Enclosure
Services switch
Power Sequence
OFF OFF Normal Start
ON OFF Command Start
OFF ON Delayed Start

Mainline-Power Connectors
Main AC Power Supply on a 2104 Model DU3 or 2104 Model TU3
A mainline-power connector is on each fan-and-power-supply assembly. The connector
is a 10-amp, three-pin, polarized, IEC 320 input connector. See Figure 9, in which 1 is
the ground connection, 2 is the neutral connection, and 3 is the live connection.
–48 V Power Supply
There is one –48 V power connector on each fan-and-power-supply assembly in a 2104
Model DU3 that has this optional feature. This permits the 2104 to be connected to the
–48 V dc rack power distribution panel. The connector is a 12–pin connector (see
Figure 10).
