Safety / Static
Electrical Safety
Observe the following safety instructions any time you are connecting or
disconnecting devices to the workstation.
DANGER:An electrical outlet thatis not correctly wiredcould place
hazardous voltage on metal parts of the system or the devices that
attach to the system. It is the responsibility of the customer to ensure
that the outlet is correctly wired and grounded to prevent an electrical shock.
Before installing or removing signal cables, ensure that the power cables
for the system unit and all attached devices are unplugged.
When adding or removing any additional devices to or from the system,
ensure that the power cables for those devices are unplugged before the
signal cables are connected. If possible, disconnect all power cables from
the existing system before you add a device.
Use one hand, when possible, to connect or disconnect signal cables to pre-
vent a possible shock from touching two surfaces with different electrical
potentials.
During an electrical storm, do not connect cables for display stations, print-
ers, telephones, or station protectors for communications lines.
To prevent electrical shock hazard, disconnect the power cable from the
electrical outlet before relocating the system.
CAUTION:This product is equipped with a three-wire power cable
and plug for the user’s safety. Use the power cable in conjunction
with a properly grounded electrical outlet to avoid electrical shock.
Static-Sensitive Devices
WARNING: Adapters, planars, diskette drives, and disk drives are
sensitive to static electricity discharge. These devices are wrapped in
antistaticbags toprevent thisdamage.Take thefollowing precautions:
• If you have an antistatic wrist strap available, use it while handling the
device.
• Do not remove the device from the antistatic bag until you are ready to
install the device in the system unit.
• With the device still in its antistatic bag, touch it to a metal frame of the
system.
• Grasp cards and boards by the edges. Hold drives by the frame. Avoid
touching the solder joints or pins.
• If you need to lay the device down while it is out of the antistatic bag,
lay it on the antistatic bag. Before picking it up again, touch the anti-
static bag and the metal frame of the system unit at the same time.
• Handle the devices carefully in order to prevent permanent damage.

Tools Required
A Phillips (cross) and standard (flat) screwdriver is needed to install or re-
move the components in this server.
Server Preparation
1. Unpack your server, do not connect the power cord.
IMPORTANT: Most servers uses anAT power supply that has a
fixed On and Off switch located on the front. This server uses an
ATX power supply that is normally off until an electrical signal is given to
the power supply through a momentary switch located on the front of the
server. There is always a standby power in the power supply in order for
ATXpower supply featuresto work, therefore removingthe power cordis
necessary to prevent electrical shocks when working on the server com-
ponents.
2. Unlock the keylocks if necessary. This server is equipped with three
securitylocks to prevent unauthorized access.Turnthe key counterclock-
wise to unlock and clockwise to lock the side panels or front door.
3. Open the front door and side panels to install final server components,
such as CPU, Memory, Hard Disk Drives, expansion cards. Use this
hardware reference guide along with your motherboard manual in order
to make these installations.
4. Connect a Keyboard and Mouse (purchased separately)
5. Connect a VGA-compatible monitor (purchased separately)
6. Connect a printer to the parallel port if desired.
7. Connect server to network (an optional network card is needed)
WARNING: To prevent electrical shock or fire, be sure not to
plugtelecommunications/telephone cables into the networkRJ45
connector in the server if one is installed.
8. Connect power cord to the server’s power supply.
9. Connect Server toAC power - The power supply will automatically de-
tect and adjust to 120VAC or 240VAC power.
WARNING: This server is designed for connection to a grounded
(earthed) outlet. To reduce the risk of electrical shock or damage to
your server, do not bypass the grounding plug.

Starting
Starting the Server
Turn on the system unit by turning the power knob clockwise and pushing
inwards momentarily.The power button will snap back becauseATX power
systems have a electrical On/Off switch unlike AT systems which require a
permanent On or Off position. If the power indicator does not light, make
surethe powercord isconnected tothesystem unitand toa workinggrounded
outlet.
When booting your server for the first time, hold the “Delete” key and enter
BIOS setup in order to make settings. ISA cards requires that you set “IRQ
XX Used by ISA : Yes” in BIOS PNP AND PCI SETUP in order for that
IRQ to be reserved for your ISA expansion card. You need to set “Boot
Sequence : A, C” in BIOS FEATURES SETUP in order to boot from a
floppy diskette to setup your hard disk. Insert a bootable floppy diskette and
select “Save & Exit Setup” from the BIOS main menu. Once your server
has properly booted, an “A:\>” prompt will appear. Replace your boot disk
with a RAID setup diskette and setup your RAID. Reboot your server with
the operating system boot disk in order to install drivers for your devices
(such as CD-ROM and SCSI devices) and install your server operating sys-
tem. You may be prompted for manufacturer supplied driver diskettes for
each device on your server if they are not included in the operating system
setup drivers.
NOTE: Non-RAID hard disk drives can be setup using boot dis-
kettes provided with the server operating system or with MSDOS
“FDISK.EXE”. You must have the motherboard or other SCSI de-
vice driver diskettes when prompted by the operating system setup.

Circulation System
The server’s air circulation system is comprised of five 3 inch (8 cm) fans
mounted on a metal fan module. The circulation system cools the hard disk
drives by bringing fresh air in from the front and forcing the hot air out
through the back. It is important to keep the air surrounding the hard disk
drives below 122˚F (50˚C) to prevent hard disk failures.
Fan Replacement
The fan module can be removed by pulling the handle and inserted by push-
ing. The handle must be in the out position to insert the fan module. The
individual fans are secured by two clips and two hooks.To release these clips,
use a screw driver to push these clips in and then slide the fan out. If an
individual fan fails, remove the fan and send it back to the vendor for replace-
ment. If all five fans fail, it may be that the fan control board needs replacing,
remove the control board and send it back to your vendor for replacement.
When replacing fans, be sure
that the fan rotations are in the
same direction. Use the
manufacturer’s sticker on one
side of the fan as a reference as
to the side. Air flows from the
front of the server to the rear.

Hot-Swap Trays
Maximum uptime in a server requires devices that can be easily replaced or
“swapped.” The main hard disks are mounted in internal hot-swap trays for
easy replacing.To remove the tray, unlock the tray and pull on the handle.A
lock secures the handle and switches on or off the power to the hard drive.
Hot-Swap Tray Interface
The front of the hot-swap tray provides a keylock in order to switch the
power on, which also locks the handle, and switch the power off, which also
releases the handle.Two LEDs provide information on the power and activ-
ity status of the hard disk drive. When power is received by the hot-swap
tray’s connector board, the power LED will light. When data is written or
read to or from the contained hard disk drive, the activity LED will flash
proportional to the amount of data.

Hot-Swap Tray Front Connections
The hot-swap tray provides wires for connecting the activity LED, power
LED, SCSI ID, power, and SCSI signal. Connect the 8 pin connector to the
SCSI Address pins according to the colors shown. Connect the 2 pin con-
nector to the activity signal pins according to the colors shown.
IMPORTANT: The following is only an example. Always consult your
hard disk drive documentation or labels for the exact wiring specific to your
hard disk drive make and model.
Hot-SwapTrays
Hot-Swap Tray Usage
Each hot-swap tray provides an aluminum carrier for a single SCSI hard
disk drives with a maximum height of 1 5/8 inch, width of 4 inches, and
length of 6 inches. The aluminum tray provides protection and maximum
heat dissipation for almost all types of high speed SCSI disk drives. The
provided cables and wires connect to the SCSI hard disk drive and screws
are needed to secure the tray to the bottom of the SCSI hard disk drive.
