Front Panel Com ponents
The DEU front panel comprises seven major
components: Operator Control Panel, Power -On
Indicator LED, Status In dicator LED s, Alarm Speaker ,
Door Loc k, Status LED s, and Activi ty LEDs.
Status Indicator LEDs
Channel Mode LED
Power Supply LED
Fan Status LED

Status LEDs
Operator Control Panel
The Operator Control Panel (OCP) provides for the
control and mon itoring capabilities of th e DEU disk
drives, power supplies, fans, and processor. From the
panel’s interface, the user can change SCSI IDs for the
drives and SAF-TE processor, monitor the cabinet
temperatur e and chan ge the temper ature thr eshold for
the monitor ing syste m.
Other menu functions prov ide for viewing component
system status, sile ncing th e audible alarm, establishing
a password protection, determining which feature cards
have been installed, establishin g intra-cabin et
communic ations (master/ slave) and r eading fir mware
information.
Note:
Activity LEDs
LEDs normally visible
only when illuminated,
shown here for identification.
PRINTER NOTE: Page size 9” x 9.25”. Align t his page to top, right ha nd corner. Back box bleeds off
top and righ t edge. Left side of page extends to 9.25 inches.
The OCP provides a four line by twenty character
display. There are five func tion keys for a menu driven
interface .
An animated icon will appear on a static display and
provides an “at-a-glanc e” look at system statu s. When a
“happy” animate d face appear s, all systems are
indicating a nominal state. Whe n the animated fac e
chang es to a “sad” face, th e system indic ates that a
problem has bee n detected an d requests y our attention .
The “power system” status will display the total power
available per dr ive slot in red undant and n onredund ant mode. A maximu m supported value of 30
watts per driv e bay is available in either mode. The
user can also view ind ividual pow er supply statu s and
configurations.
Cabinet temperatu re is measured w ithin the dr ive bay
area between drive slots 2 an d 3, and slots 7 and 8. By
sensing c abinet temperatur e in these loc ations, the
system provides the most sensitive measurement for
maximum protec tion. The temperature is d isplayed in
both Celsius and Fahrenheit. A SAF-TE processor
monitors the performan ce of each of the fan s via tach
pulses which tracks the speed of each fan impeller. The
OCP displays in formation abou t the speed of e ach fan.
Fan speed is co ntrolled via th e internal c abinet
temperatur e, refer enced fr om the user -established
temperatur e threshol d.
Power-On LED
The Power-On LED signifies that the DEU system has
power applied.
Status Indicator LEDs
There ar e three Statu s Indicator L EDs to assist the
user in dete rmining th e curren t state of the DEU
subsystem. Th e followin g subsection s describe eac h
LED.

Channel Mode
Power Supply Status
The Chann el Mode LED indicates the status of the
array su bsystem by ch anges in its co lor and state.
When illuminated steady g reen, the LED in dicates
normal arr ay activities.
When the L ED chang es to amber (flash ing or ste ady) it
indicates abno rmal activities, f or more info rmation see
LED Descriptions described late r in this gu ide.
The Powe r Supply Statu s LED indicate s the conditio n
of the power supplies by change s in its color. The LED
will illuminate steady gr een when all the pow er
supplies are func tioning nor mally and will chan ge to
amber if one o f the power supplies should f ail. The LED
will also switch to amber if the pow er system is in a
non-re dundant state. A failed compon ent can be
identified v ia the Operator Control Pane l and the lack
of a “DC Good” LED located on each power supply unit.
Fan Status
Alarm Speaker
The Fan Statu s LED indicate s the conditio n of the
cooling fans by changes in its c olor. The LED w ill
illuminate green w hen all of the fans are f unctioning
normally an d will chang e to amber if any of the fans
should fail.
When a failed component is present, use the Operator
Control Panel to identify the failed fan, see Hardware
Menu described later in this guid e. The fans ar e
identified on the rear doo r panel via plac arded
marking s.
An audible alarm will soun d when any component’s
condition change s to an abnormal state. The Status
Indicator LEDs will pr ovide a general area of failure by
the LED co ndition (colo r and/or state ), and the faile d
componen t can then be identified using the Oper ator
Control Panel.
To silence th e alarm, acce ss the contr ol panel and
select “Tur n Off Alarm”, see Main Menu described late r
in this guide.
PRINTER NOTE: Page size 9” x 9.25”. Align t his page to top, right ha nd corner. Back box bleeds off
top and righ t edge. Left side of page extends to 9.25 inches.
Door Lock
Status LEDs
The fron t door has an integral loc k that also serv es as
a door handle. In addition, the door lock provides
security to deter un authorize d access to the internal
components. Two keys are provided with the system.
To unlock the door, insert the key and tu rn it in a
counterclockwise direc tion. To lock the door, turn the
key in a clockwise direction.
There ar e eight Status L EDs located in th e window s on
the front panel (for the rack-mount system they are the
lower set of LEDs and for the tower -based system will
be the set on th e left hand sid e).
These LEDs, in conjunction with an approved RAID
controlle r, will indicate the status of that spe cific disk
drive. The con dition of the drive is indicated by the
LED’s state (f lashing or steady) and/ or color (amber or
green).
Activity LEDs
For more in formation on interpretin g these indic ations,
see LED Descriptions described later in this guide.
There are eight Activity LEDs located in the windows
on the front panel (for the rack-mount system they are

The I/O Interface card makes up the connection from
the subsystem’ s bus to the RAID controlle r. Located on
the I/O I nterface c ard are two 68-pin ver y high density
(VHD) SCSI connectors. They provide the in terface
connec tion from th e subsystem bus to the RAID
controller or host adapter. The connectors are labeled
Channel 0 an d Channel 1.
PRINTER NOTE: Page size 9” x 9.25”. Align t his page to top, right ha nd corner. Back box bleeds off
top and righ t edge. Left side of page extends to 9.25 inches.
The I/O Interface card inco rporates bu ilt-in automatic
SCSI termination. When the data c able is plugge d in,
the system au tomatically senses th e conne ction and
provides the required SCSI termination.
Two sets of jumpers are provided on the card. One set
routes Term Power in the event that the host controller
is not providing it.
The nex t set of jumper s addresses a spe cific set of
controllers that use the DEC Fault Bus protocol. If you
are using a DEC system where the controller uses this
protocol, you w ill need to jumper locations (jumper on
both pins) JP3 an d JP4 for eac h chann el that has an
external SCSI cable con nected. This will disable
termination at th at point.
If you ar e using a stan dard host adapter that prov ides
Term Power, no ch ange is required and SCSI bus
termination w ill occur au tomatically.
Power Cord Connector and Fuse
The power cord connector supplies the AC power to the
DEU through a power cord connected to a conventional
three-h ole groun ded outlet or p ower strip. A 250V 10
amp fuse is provided to protect the system from any
electrical f ault.
Internal Components
There ar e seven pr imary inter nal compon ents: disk
drives (up to eight), Fault LEDs, power switch, SAF-TE
card, h ot swappable coo ling fans, h ot swappable pow er
supplies, and configuration module (Dual-Bus or
Single-Bus).

I/O Interface Card
The DEU uses high performance, 3.5-inch form factor
hot swappable disk drives. The drives are designed to
operate on Small Computer System Interface (SCSI)
and are SCSI-3/ SCSI-2 command c ompatible.
Each drive has an 80-pin Wide Single Connector
Attachment (SCA-I I) interface , designed to allow the
drive to be h ot plugge d directly in to the backplan e.
PRINTER NOTE: Page size 9” x 9.25”. Align t his page to top, right ha nd corner. Back box bleeds off
top and righ t edge. Left side of page extends to 9.25 inches.
Power Switch
The drive mounting design incorporates a rail system
with built-in connec tors making it po ssible to “hot
swap” a drive without sh utting dow n the system. This
design allow s for easy installation with minimal for ce
and latchin g clips to secu re the driv es into place.
Note: All drives in an array shou ld be of the same
capacity. If the drives are mixed, all of the dr ives in
the array are assigned the capacity of the smallest size
drive.
The power switch is located inside the lockin g front
door and controls AC power to all of the power supplies.
This positioning of the switch deters unauthorized
users from powering down the D EU provided the door
is locked. The switch is recessed to prev ent inadvertent
activation du ring ser vice activ ity.
The switch is labeled with a “I” for the ON condition
and “O” for the O FF condition and is illu minated when
the power is on for easy identification. Depending on
the orien tation of the su bsystem (i.e. , in the r ack
configu ration) the “I” label will appear as a — and
should be inte rpreted as the ON condition .
Fault LEDs
SAF-TE Card
Drive Fault LEDs are provided inside the front door to
aide in identifying the failed (or problem) disk driv e.
These LEDs are aligned with their respective
drive/dr ive bay. An illu minated LED (amber) in dicates
the failed or problem drive.
The SAF-TE card contains the control and monitoring
electron ics for the subsystem cabin et. It prov ides the
central data lin k between th e enclosur e and the host
system.
PRINTER NOTE: Page size 9” x 9.25”. Align t his page to top, right ha nd corner. Back box bleeds off
top and righ t edge. Left side of page extends to 9.25 inches.
Located in th e tower-base d systems’ top bay or the
rack-mount systems’ far left bay are two card slots. The
Ultra S2S RAID Controller (optional) an d the SAF-TE
card are installed in these two slots. The Ultra S2S
RAID Controller w ill be installed in the upper most (o r
furthest left) slot. Th e SAF-TE card is installed in the
next slot down or to the right.
Hot Swappable Cooling Fans
The cooling system consists of two high-performance
fans fitted to the rear panel. These fans draw air from
a high pressure plenum, across the drives and
electronics of the system and exhaust out through the
rear door panel.
The fan speed is thermally controlled to provide
reduced operating noise levels. In the event of a fan
failure or cabinet temperatu res approac hing the
threshold limit, th e remaining f an will switch to
maximum operating speed.
Cabinet temperatu re is measured w ithin the dr ive bay
area between drive slots 2 an d 3, and slots 7 and 8. The
fan’s speed and alarms are k eyed to the h igher o f the
two temperatures. The SAF-TE processor monitors the
Access the O perator Con trol Panel to dete rmine the
cause and f ailed compone nt. Select “Har dware Me nu”
from the M ain Menu and choose “Component Status”,
see Operator Control Panel described later in th is
guide. The fans are identified on the rear door panel
using a plac ard for “FAN 1” and “FAN 2.” For more
information on chang ing a coolin g fan, see Replacing
the Cooling Fans desc ribed later in this guide.
Hot Swappable Power Supplies
Up to three 150 w att hot swappable po wer supplie s are
incorpo rated as part of a f ault-toleran t design (N+1
power system). Each power supply has current share
circuitr y whic h balances the lo ad between installe d
power supplies. In the event of a power supply failure,
the load is tran sferred to th e remainin g power su pplies
without in terruption to the DEU nor mal operation.
PRINTER NOTE: Page size 9” x 9.25”. Align t his page to top, right ha nd corner. Back box bleeds off
top and righ t edge. Left side of page extends to 9.25 inches.
If a failure o ccurs, the Power Supply Status L ED will
illuminate amber an d the audible alarm w ill sound. Th e
user can id entify the f ailed componen t by accessing the
OCP and vi ewing the “Hardware Status.” The PSU “D C
Good” LED will not be illumin ated on the failed power
supply, see Replacing a Powe r Supply describe d later
in this guide.
PRINTER NOTE: Page size 9” x 9.25”. Align t his page to top, right ha nd corner. Back box bleeds off
top and righ t edge. Left side of page extends to 9.25 inches.
Configuration Modules
The DEU is available in two bus con figuration s which
is determined by the conf iguration mo dule installed.
The Dual-Bus modu le provides for a split bus desig n,
while the Single-Bus module connects both SCSI buses
together that can be used when all driv es are requir ed
on one SCSI bus.
The Single-Bus module is larg er in physical size th an
the Dual-Bus modu le and is easily identified by a
description silk-screened on the module card. It is
located on th e backplane pr inted circ uit board and is
accessed from the rear door panel.
The con figuration modules are installe d at location JP1
on the backplane PCB. The connector is keyed and th e
module will install only on e direction. For illu stration
purposes, the tower system is used to depict the
location of th e modules.

SAF-TE
The DEU is designed to be compliant with SAF-TE
(SCSI Accessed Fault-Tolerant Enclosure) specification
version 1.0. Un der this specification, the enclosure is
implemented as an assignable SCSI targ et ID. Th is
allows standardized alert detection and status
reportin g using th e SCSI bus as the u nderlyin g
transport me chanism.
Disk drives, power supplies, cooling fans and
temperature are contin ually monitor ed and these
conditions are then reported over the SCSI bus to the
host system. When used in conjunction with RAID
managemen t software, th e DEU can aler t the user o r
LAN administrator of impending or imminent
conditions r equiring th eir attention. T hese alert
notification s can be made v ia network broadcast or
electronic pages, in addition to the LEDs and Oper ator
Control Panel alerts found on the DEU. This allows the
administrator to react to con ditions that cou ld normally
go unnoticed until data loss.

2 Installation
Setup
The installation o f your D EU disk array su bsystem is
essentially a th ree-step pr ocess: the su bsystem is setup
and its compon ents installed, th e cabling is co mpleted
based on the su pported c onfigur ations, and th e array is
then configured.
The DEU is designed with an open arch itecture that
allows for many possible combinatio ns of cabling
schemes. D ue to the in herent limitatio ns of sampling
all of the possible configu rations, we will pr ovide a few
of the most ty pical cabling schemes and impl ementation
of the con figuration modules.
Additional con figuration s are available thr ough the use
of Ultra Extender or Differential Converter Option
cards. Refe r to Appendix D for info rmation specific to
each card and configuration.
This chapte r is divided in to two section s: Setup and
Cabling Configuration. The Setup section provides the
instructio ns for assemblin g the rack -mount subsy stem,
and installing the h ardware componen ts (controllers,
disk drives, power supplies, etc.,) for both rack-mount
and deskside tower-based subsystems.
The Cabling Configuration section contains samples of
cabling sch emes and con figuration modules. If y our
desired configuration is not shown in the samples, refer
to the example mo st similar and follow the cabling
topology schemes exp anding the example to fit y our
needs.
When configuring the array, refer to the Ultra S2S
RAID Controller User’s Guide provided with your

Guidelines
Before installation, you will need to co nsider the
following:
When referenc ing a component on the rear panel it is
■
assumed the user is facing the rear panel and when
referen cing the front panel c omponents th e
assumption is that th e user is fac ing the fr ont panel.
Interior temperatur e of the rac k cabinet sho uld be
■
maintained at ambien t temperature s but must not
exceed 117°F (47°C) during normal operation.
Remove each piece from the shipping carton, leaving
■
the disk driv es in their an ti-static protectiv e
packaging until you are ready to install them. Save
the packin g materials in c ase you ne ed to ship the
DEU.
Secure all cable connectors using the thumb screws
■
(finger tight only).

Rack-Mount Subsystem Assembly
Install the DEU in to any standar d IAE 19" rack
cabinet.
Caution: Ensure th at the location o f the DEU does no t
create an u nstable condition when in stalled in the rac k
cabinet enclosure.
Note: Mount th e subsystem into the rack e nclosure
before installing the disk drives. Th is will reduce th e
weight required to support during installation.
Select an appr opriate location in your r ack cabinet

for the DEU. If you are installin g multiple systems,
review th e cabling c onfigur ation section late r in this
chapter f or your cable scheme to determine th e
optimum location .

Cabling Configur ation
This section provides the recommended c able
configurations when operating the DEU in a specific
mode.
The Ultra Wide SCSI mode provides enhanced
perfor mances with data transfer s up to 40 MBs per
second (20 MHz).
Note: Be sure to enable the Ultra SCSI (Fast-20) mode
in the SCSI Adapter Setup.
The DEU sup ports the Amer ican National Stand ard
Ultra SCSI (Fast-20) par allel interfac e standards,
referred to as Ultra Wide SCSI. This standard is
backward compatible with F ast SCSI (SCSI-2 with th e
Wide option), also referr ed to as Fast Wide SCSI.
These standar ds define the me chanical, e lectrical, an d
timing requ irements. In compliance w ith these
interfac e standards, c ertain limitations app ly when
considering the configuration, lengths of cabling, and
termination. The conf iguration samp les and cables
provided with the subsy stem meet the r equirements o f
the specific ations. Mo difications to an y of these
variables can have less than desirable re sults when
operating any SCSI dev ice.
Termination
Termination is required at bo th ends of th e SCSI bus.
There are two sets of jumpers on the I/O Interface card.
One set of jumpers routes “Term Power” in the event
that the host controller is not providing it. The default
setting is the unjumpered condition (jumper offset on
one pin only). The secon d set of jumpers addresses a
specific set of controller s that use the D EC Fault Bus
protocol. If your controller uses this protocol, you will
need to jump er (jumper on both pins) at location JP3
and JP4 on th e backplane fo r the indic ated chann el
that will be used. A jumper at either of these location s
will disable termination at that poin t on the SCSI bus.
If you are using a controller that provides Term Power,
no chan ge is requir ed and SCSI bus ter mination will
occur automatically.
The Host Controller card provides termination for one
end of the SCSI bus, while the I/O In terface c ard
provides final termination at the other end of the bus.
