Preface – Important Safety Instructions, Care and Handling
Important Safety Instructions, Care and Handling
Before starting, take a few minutes to read this manual.
Read all of these instructions and save this manual for
later reference.
Protect the disk array system from extremely high or low
temperatures. Let the disk array system warm (or cool)
to room temperature before using it.
Protect the disk array system from being bumped or
dropped. Do not place the disk array system on an
unstable cart, stand, or table. It may fall, causing serious
damage to the product.
Keep the disk array system away from magnetic forces.
Do not use the disk array system near water.
Keep the disk array system away from dust, sand, or dirt.
Gaps and openings in the cabinet are provided for ventilation. Never block or cover these openings, because
the disk array system may overheat and become unreliable. Don’t place the disk array system on a bed, sofa,
rug, or other similar surface.
Do not place the disk array system near or over a radiator or other heat source.
Refer to the rating plate for the correct voltage and
ensure that the appliance voltage corresponds to the
supply voltage.

Preface – Important Safety Instructions, Care and Handling
The appliance must be grounded. The disk array system
is equipped with a 3-wire grounded type of power cord.
This power cord will only fit into a grounded type of
power outlet.
If an extension cord or a power center is used with the
disk array system, make sure that the total current consumption of all products plugged into the wall outlet
does not exceed the ampere rating.
Do not place the disk array system where the cord will
be walked on.
Never push any kind of object into the disk array system
through cabinet gaps and openings, since they may
touch dangerous voltage points and cause a risk of fire
or electric shock.
Unplug the power cord from the wall outlet before cleaning. Keep the disk array system dry. Do not use liquid
cleaners, aerosol cleaners, or a wet cloth. Use a damp
cloth for cleaning.
Except as specifically explained in this User Manual, do
not attempt to service the disk array system by yourself.
Opening or removing the covers may expose you to
dangerous voltages.
Unplug this product from the wall outlet and refer servicing to qualified service personnel under the following
conditions.
• If the disk array system has been exposed to
water or any liquid.
• If the disk array system has been dropped or the
cabinet damaged.
Users should not remove the cover.
Disconnect all power supply cords before servicing.

Preface – Important Safety Instructions, Care and Handling
Placement Notes
• The disk array system LCD panel can be damaged by exposure to
direct sunlight. Limit exposure to subdued or indirect sunlight only.
• The disk array system should be used only in clean environments
that are free from airborne contaminants such as dust, dirt, and
smoke. Excessive moisture or oil particles in the air can also hinder
disk array system performance.
• To reduce the possibility of data errors caused by electromagnetic
interference, locate the disk array system at least five feet away
from electrical appliances and equipment that generates magnetic
fields.
Power Supply Safety Notes
• To avoid electric shocks, do not use an extended power cord or an
outlet that does not match the disk array system plug or leaves the
plug exposed.
• The disk array system has a 3-wire grounded plug. The third pin
connects to ground; do not remove it.
• If the power cord or plug is damaged or worn, unplug it immediately
and contact a qualified service technician for maintenance.
• To avoid fire or electric shocks, do not overload electric power outlets.
CAUTION : MULTIPLE POWER SOURCES
Disconnect all AC power cords to completely power from the unit
CAUTION
Risk of explosion if battery is replaced by an incorrect type.
Dispose of used batteries according to the instructions.
CAUTION
The thumbscrews on the rear surface shall be secured by the screwdriver, which cannot be loosened by bare hands to prevent the unintentional access to the hazardous parts inside the equipment.

3Maintenance
Replacing a Disk
A disk failure is indicated when the Power/Error LED at the front of the drive tray turns
red and the audible alert sounds.
The LCD panel displays the failure with the symbol “R” or “W”. “R” indicates a disk failure or error, and “W” indicates that there are too many bad sectors on the disk.
Disks are hot swappable, which means that they can be inserted and removed while the
disk array system is powered on and operating. Follow these instructions to replace a
failed disk.
1 Unlock the front panel door, then pull it open.
2 Pull the tray handle away from the disk tray to release it; and pull the disk tray
out.
3 Remove the screws from the failed disk, then remove the disk from the disk tray.
4 Align the rear of the new disk with the rear of the disk tray.
5 Insert the new disk into the disk tray.
6 Attach the disk to the disk tray with the screws that came with the disk.
7 Slide the disk tray back into the empty slot, then close the disk tray handle.
8 Push the front panel door closed, and lock it.
Note
Turn off the audible alert by pressing the Up and Down function buttons on the front panel twice simultaneously.
Note
The new disk must have the same or a greater capacity than the
faulty disk that was removed. If the disk capacity is smaller, the
audible alert sounds and the auto-rebuild operation doesn’t start.
For best performance, it is recommended that the new disk be
identical to the failed disk.
111222WR
Example:
• Disks 1 to 3 are members of array group 1.
• Disks 4 to 6 are members of array group 2.
• Disk 7 has too many bad sectors.
• Disk 8 has an error or a fault.

3 Maintenance – Replacing a Power Supply
Replacing a Power Supply
The disk array system is equipped with a Power Supply Fail Indicator LED at the front of
the unit that turns red when one of the power supplies fails. The message “Power x failure” also appears on the LCD panel, where x refers to power supply 1, or 2, and an
audible alert sounds.
Power supplies are hot swappable, which means that they can be inserted and removed
while the disk array is powered on and operating. Follow these instructions to replace a
failed power supply.
1 Identify the power supply that has failed.
2 Remove the power cable from the power supply connector at the rear of the unit.
Note
Turn off the audible alert by pressing the Up and Down function buttons on the front panel twice simultaneously.
Note
The system is equipped with auto switching power supplies that
can run on 100 to 240 VAC.

3 Maintenance – Upgrading Memory
Upgrading Memory
The disk array system takes a single DDR 184pin DIMM with a maximum capacity of 1
GB. Follow these instructions to upgrade the memory.
1 Remove the screws from the disk array system and pull the controller box.
2 Retaining away, the DIMM springs out of the socket. Remove the DIMM.
3 Gently push the new DIMM into the socket, then push the corners of the DIMM
down. The DIMM is secured by the DIMM retaining clips.
