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 prevent a possible shock from touching two sur-
faces with different electrical potentials.
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
IMPORTANT
Motherboards, adapters, and disk drives are sensitive to static
electricity discharge. These devices are wrapped in antistatic
bags to prevent this damage. Take the following 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 antistatic bag and the metal frame of the
system unit at the same time.
• Handle the devices carefully in order to prevent permanent
damage.

III. Basic Operation
• 3-1. Starting the Server
Turn ON the server by turning the power knob clockwise and pushing in-
wards momentarily. The power button will snap back when released be-
cause ATX power systems have an electrical ON/OFF switch unlike AT
systems which require a permanent ON or OFF position. If the Power On
LED does not light, make sure the power cord is connected to the system
unit and to a working grounded outlet.
IMPORTANT
The power switch only turns off DC power (power supply output).
To turn off AC power (power supply input), you need to unplug the
electrical cords from the redundant power supply.
• 3-2. LED Indicators
The LED indicators are located on the top-left edge of the front panel. The
Power LED lights when the motherboard receives power from the power
supply. Activity LED lights when there is activity from IDE or SCSI de-
vices connected to the motherboard. Fan #1-5 lights if the corresponding
fan stops turning.

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 transferred.

Using the SCSI Backplane Boards Separately
Each SCSI backplane board supports four hard drives. If you are only in-
stalling four or less hard drives in the hot-swap bays, only one SCSI
backplane board is needed. You may also use two SCSI channels and treat
each SCSI backplane board separately. The SCSI ID for the hard drives
used in each slot is determined by the SCSI ID DIP switch. The switch
controls two sets of SCSI IDs so individual ID settings cannot be made.
The following table shows the results when setting the SCSI ID switch to
either the ON or OFF position.

Using Cascaded SCSI Backplane Boards
If installing five or more hard drives in the hot-swap bays, two SCSI
backplane boards are required.Atwo-channel SCSI controller can com-
bine two separate sets of hard drives through software RAID or by
using a hardware RAID controller. Cascading the SCSI backplane boards
can be done to use only a single channel on the SCSI controller.

Fan Module
The server’s fan module is comprised of five 3-inch (8 cm) fans. The circu-
lation system cools the hard disk drives by bringing fresh air in from the
front and forcing the hot air out through the back. If an individual fan fails,
the corresponding LED on the front of the server lights.
Fan
Replacement
The fan module can be removed
by pulling the handle out. The
handle must be in the out position
to insert the fan module. The in-
dividual 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.
IMPORTANT
When replacing fans, be sure that the fan rotations are in the same di-
rection. Use the manufacturer’s sticker on one side of the fan as a refer-
ence as to the correct side. Air should flow from the front of the server
to the rear.

IV. Hardware Setup
Power Module Rating
The redundant power supply consists of one frame and two identical ATX
power modules. The power supply must be turned on or off through an
ATX power switch connected to the motherboard’s panel connector. The
power modules are rated at 400W each and have passive current sharing on
all outputs. Each power module supplies up to 400W to share the load but
two modules combined do not provide 800W. If one power module fails,
400W load is supported using one power module.
CAUTION
Before turning ON your server for the first time, set the power
supply’s voltage. Some products may have auto voltage switch-
ing to accommodate 220V-240V or 110-120V but this power
supply must be set manually. The factory default should be on
230V to accommodate the higher voltage but it is safer to visu-
ally inspect the switch yourself in case it is not. Using the power
modules set on 115V in 230V environments may cause damage
to the power modules.
IMPORTANT
For countries using 110V-120V, you must slide the switch to 115V
or else power up is not possible (but no damage will occur).
Power Module Failure
If any of the power modules fails to provide a voltage on any of its outputs,
an audible alarm (located in the frame) will sound and the failed power
module’s LED will turn OFF. The power module’s status LED lights when
both input and output voltages are stable and darkens if either the input or
output voltages fail. If the alarm sounds, perform the following steps:
1. Remove the power cord to the failed power module (with dark LED).
2. Remove the two screws and slide the failed power module out. The
alarm should stop. If not, there may be a problem with the other module
or with the redundant power supply frame (very unlikely).
3. Reinsert the failed power module and plug in the AC cord to confirm.
4. If the alarm sounds again, remove the failed power module and replace
it with a good one as soon as possible.

i. SCSI Cable Limits
SCSI cables have a limit to the length that it may have. Exceeding the length
may cause problems mounting or using any one of the SCSI devices.
CAUTION
Exceeding the SCSI cable limits may cause unreliable data trans-
fers even if all the devices are mounted properly.

IMPORTANT
• Narrow refers to 50 pin and Wide refers to 68 pin. Don’t get
confused by the width of the connector or cable.
• The SCSI ID for devices on one connector cannot be the same
as the SCSI ID for devices on the other connectors. None of the
devices on any connector can use ID7, which is reserved for
the SCSI controller.
• Amaximum of 15 devices may be connected to the motherboard
(three connectors) at one time.
NOTE
• Atotal of 15 “Ultra2-SCSI” devices (ID0-ID15) may be connected
to the 68-pin Ultra2 connector on the motherboard.
• If connecting Fast/Ultra devices with Ultra2 devices on the Ul-
tra2 connector, the entire SCSI bus will be limited to the Ultra
SCSI conditions listed above. Mixing SCSI devices is highly
not recommended.
• A total of 8 “Wide Ultra-SCSI” devices (ID0-ID15) may be con-
nected to the 68-pin Wide connector if using a 1.5m (4.9ft) cable,
but only 4 “Wide Ultra-SCSI” devices if using a 3m (9.89ft) cable.
Ultra-SCSI technology is unstable over long lenghts, therefore sta-
bility will depend on they quality of your cable and devices.
• Atotal of 15 “Wide-SCSI” devices (ID0-ID15) may be connected
to the 68-pin Wide connector.
• A total of 7 “Narrow Ultra-SCSI” devices (ID0-ID6) may be
connected to the 50-pin Narrow connector when using 1.5m
(4.9ft) cable but only 4 devices when using 3m (9.8ft) cable.
Ultra-SCSI technology is unstable over long lengths, therefore
stability will depend on the quality of your cable and devices.
• Atotal of 7 “Narrow Fast SCSI” devices (ID0-ID7) may be con-
nected to the 50-pin Narrow connector.

ii. Glossary
Byte (Binary Term)
One byte is a group of eight contiguous bits. A byte is used to represent a
single alphanumeric character, punctuation mark, or other symbol.
CHKDSK (Check Disk)
An MS-DOS command that gives you information such as disk space, files,
and directories on your hard disk drive.
COM Port
COM is a logical device name used to designate the computer serial ports.
Pointing devices, modems, and infrared modules can be connected to COM
ports. Each COM port is configured to use a different IRQ and address
assignment.
CPU (Central Processing Unit)
The CPU, sometimes called “Processor,” actually functions as the “brain”
of the computer. It interprets and executes program commands and pro-
cesses all the data stored in memory. Currently, there are socket 7, slot 1,
and slot 2 CPUs. Intel Pentium Processors fit on socket 7, Intel Pentium II
fit on slot 1, and Intel Xeon fit on slot 2.
Endian
Endian is a byte order system used in data transfers. In big-endian architec-
tures, the lower addresses are most significant. In little-endian architectures,
the higher bytes are most significant. Mainframe computers, such as those
by IBM, use a big-endian architecture. Modern PCs use the little-endian
system.
FDISK (Fixed Disk Setup Program)
An MS-DOS program used to partition the hard disk drive. FDISK is re-
quired to setup a new non-RAID hard disk drive before formatting and in-
stalling an operating system.
IDE (Integrated Drive Electronics)
IDE devices integrate the drive control circuitry directly on the drive itself,
eliminating the need for a separate adapter card (in the case for SCSI de-
vices). UltraDMA/33 IDE devices can achieve up to 33MB/Sec transfer.
LPT Port (Line Printer Port)
Logical device name reserved by DOS for computer parallel ports. Each
LPT port is configured to use a different IRQ and address assignment.

PCI Bus (Peripheral Component Interconnect Local Bus)
PCI bus is a specification that defines a 32-bit data bus interface. PCI is a
standard widely used by expansion card manufacturers.
Peripherals
Peripherals are components on the outside of the computer such as a moni-
tor, printer, keyboard, or mouse. Peripherals are attached to the computer
via I/O ports. Peripheral devices allow your computer to perform an almost
limitless variety of specialized tasks.
POST (Power On Self Test)
When you turn on the computer, it will first run through the POST, a series
of software-controlled diagnostic tests. The POST checks system memory,
the motherboard circuitry, the display, the keyboard, the diskette drive, CPU,
and other I/O devices.
PS/2 Port
PS/2 ports are based on IBM’s Micro Channel Architecture. This type of
architecture transfers data through a 16-bit or 32-bit bus.APS/2 mouse and/
or keyboard may be used on ATX motherboards.
RAID (Redundant Array of Inexpensive Disks)
RAID can be set up to provide mirroring (for fault tolerance), parity (for
data guarding), or striping (for data distribution over several drives for in-
creased performance). A RAID card is required to setup a RAID system.
RAM (Random Access Memory)
There are several different types of RAM such as DRAM (Dynamic RAM),
EDO DRAM (Extended Data Out DRAM), SDRAM (Synchronous DRAM).
ROM (Read Only Memory)
ROM is nonvolatile memory used to store permanent programs (called firm-
ware) used in certain computer components. Flash ROM (or EEPROM) can
be reprogrammed with new programs (or BIOS).
SCSI (Small Computer System Interface)
High speed parallel interface defined by the X3T9.2 committee of theAmeri-
can National Standards Institute (ANSI) for connecting many peripheral
devices.
UPS (Uninterruptible Power Supply)
A battery system that can provide power to an electronic device or com-
puter when power fails in the building. Apassive UPS only provides power.
An active UPS provides power conditioning that offers protection against
transient power conditions and short-term power outages.
