Important Safety Instructions, Care and Handling
Preface – 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.
V
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 heat register.
Refer to the rating plate for the correct voltage and
ensure that the appliance voltage corresponds to the
supply voltage.
ii
Page 9
easyRAID S8A2-U4TT Serial ATA Disk Array Systems
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.
Preface – Important Safety Instructions, Care and Handling
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.
User should not remove the cover.
Disconnect all power supply cords before servicing.

Placement Notes
Preface – Important Safety Instructions, Care and Handling
• 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.

Making Connections
2 Basic Configuration – Making Connections
After the required number of disks have been installed, external connections to the disk array
system must be made. This section describes how to make all of the necessary connections.
Connecting the Host Interface
The disk array system has dual SCSI interfaces. Refer to the following sections to make host
interface connections.
Small Computer Systems Interface
The easyRAID S8A2-U4TT has dual Ultra320 SCSI interfaces. Follow these instructions to
make connections.
1 Connect the active SCSI terminator to the bottom connector of the easyRAID S8A2-
U4TT host port 2 (Secondary SCSI channel) at the rear of the disk array system.
2 Connect the Ultra320 SCSI cable to the top connector of the easyRAID S8A2-U4TT
host port 2 (Secondry SCSI channel) at the rear of the disk array system.

2 Connect the second power cable to the remaining power supply connector.
Note
The system is equipped with auto switching power supplies that
can run on 100 to 240 VAC.
3 Press the disk array system power switch to the ON position. The disk array system auto-
matically begins the self-test sequence.

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.
Note
Turn off the audible alert by pressing the Up and Down function buttons on the front panel twice simultaneously.
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.
Example:
• Disks 1 to 2 are members of RAID group 1.
• Disks 3 to 6 are members of RAID group 2.
112222WR
• Disk 7 has too many bad sectors.
• Disk 8 has an error or a fault.
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 disk tray with an included disk tray key .
2 Gently pull the disk tray handle to the opened position.
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.
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.
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 Lock the disk tray with the key.

Replacing a Power Supply
3 Maintenance – 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.
Note
Turn off the audible a lert by pressing the Up and Down buttons on the
front panel twice simultaneously.
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 steps to replace a failed power supply.

automatically locks into position when fully inserted.
3 Maintenance – Upgrading Memory
6 Reconnect the power cable.
Upgrading Memory
The disk array system takes a single 200 pin DIMM with a maximum capacity of 1 GB. Follow
these instructions to upgrade the memory.
1 Remove the three screws from the disk array system cover, then slide the cover away
from the front panel and lift it off.
16
Page 27
easyRAID S8A2-U4TT Serial ATA Disk Array Systems
2 Pull the DIMM retaining clips away from the DIMM, then remove the DIMM. The
DIMM springs out of the socket.
3 Gently push the new DIMM into the socket at 45 degrees, then push the corners of the
DIMM down. The DIMM is secured by the DIMM socket retaining clips.
3 Maintenance – Upgrading Memory
Note
The DIMM module will fit in only one direction. Do not force the
DIMM into place.
