CHAPTER 1.
IInnttrroodduuccttiioonn
SOHO-RAID, which supports RAID (Redundant of Array Independent Drives)
level 1 mirroring and level 0 striping function, is an internal device especially
designed for the professional PC and PC server users. This device will be
greatly appreciated by the serious users of small and medium-sized office
servers, who wish to update their backups instantly and easily.
SOHO-RAID is a low cost, high efficiency Real-time Data Backup System. It
offers an alternative to the potential users of expensive SCSI RAID Level 5 or
low efficiency magnetic tape backup system.
The housing of SOHO- RAID is 146mm(w) and 84mm(h), which will fit into
the opening of two consecutive bays for 5.25” HDD. There are two removable
trays for two identical hard disk drives in the housing. These trays are now
empty. No Hard disk drives are supplied with SOHO-RAID. The users
themselves must buy the hard disk drives according to their own needs.
The installation will be divided into two parts. The first part is to install the
housing of SOHO -RAID into your computer or server. The second is to install
the HDD into the tray and then the tray into the housing, which is now a part of
your computer or server.
1-1 Function & Features
??Simultaneous writing to both drives in RAID level 1 function.
Automatically rebuilding data in the replacement HDD in RAID level 1
??
function.
??Drives are hot swappable without turning the system off in RAID level
1 function.
??Support IDE interface.
??Audible alarm and LCD display on drive failure.

Compatible to most leading brand Hard Drives.
??
With built -in cooling fan for high-speed HDD.
??
No software driver required.

2-2 How to Plug in and Pull out the HDD TRAY
˙Pull out the HDD TRAY
1. After open the front panel, pull the handle of HDD Tray.
2. The HDD TRAY will slide out of the housing. Take out the HDD TRAY.
˙Plug in the HDD TRAY
1.Plug the HDD TRAY into the upper/lower tracks and push it to the base.
2. Push back the HDD TRAY handles until luck it. (Indicator by pictures as followed)

2-3 Install Hard Drives to HDD Trays
??Set the hard disk drives to the MASTER mode only .
??Connect the 4-pin power socket and the 40-pin EIDE/IDE socket of Hard disk
drive to the connectors on the HDD tray of SOHO-RAID.
??Install the Hard Drive into the HDD tray
??Fix the Hard Drive on the HDD tray with the furnished screws, and then
put the power lines and EIDE/IDE cable in place, such as not to be in the
way when you push the HDD Tray in.

2-4 Install SOHO-RAID into the Computer (Server)
Turn the computer off and pull off the power plug.
??
It takes the space of 5.25” Bay x 2 to install the SOHO-RAID into the
??
computer.
The SOHO-RAID can be set as MASTER (DEFAUT) or SLAVE Mode.
??
You can change the SOHO-RAID as SLAVE Mode by set up the Jumper.
(Refer to 3-1 SOHO -RAID configuration)
Remove the Computer case and mount the SOHO-RAID unit into the
??
computer.
Connect the power line and EIDE/IDE cable to the PCB on the back of
??
the SOHO-RAID. Fix the SOHO -RAID on the computer with screw.
Put back the cover(s) of the computer’s metal case and fix it.

There are two different cases to install the HDD on the SOHO-RAID.
??
1. Install 2 brand-new Hard Drives into SOHO-RAID.
??After installing the two brand -new and identical Hard Drives into the
HDD Tray, plug the HDD Trays in the SOHO-RAID, and push the
trays all the way in. Then close the HDD Tray’s handle and the front
panel.
??If the two drives are different in capacity, put the smaller one at
first and follow the step as “Install an original Hard Drive which
contains the system software and data, and also a new Hard Drive
into SOHO-RAID” (see next paragraph). The SOHO-RAID will
limit its capacity to that of the smaller hard disk drive.
2. Install an original Hard Drive which contains the system software
and data, and also a new Hard Drive into SOHO-RAID
??Install the tray with the original Hard Drive into either tracks of the
SOHO-RAID.
??Then install the other tray follow the Operation Instruction in

As a matter of fact, the two hard disk drives in the SOHO-RAID start working
simultaneously as one right after the installation. Not only all commands from
FORMAT, and FDISK will be performed on the two hard drives simultaneously,
but all things including the booting system you will install from the CD ROM,
are also written on the two hard disk drives at the same time, if you choose the
SOHO-RAID as MASTER. (If you choose it to be SLAVE, the two hard disk
drives will act together exactly like a “D:”
3-1 Jumper setting Configurations
Except support RAID 1 mirroring and RAID 0 striping function by setting
different jumper configuration on its Rear Panel. You can configure the
SOHO- RAID by setting the jumpers as below.
How to set up the jumpers

3-2 Operation Instruction
Install 2 brand-new Hard Drives into SOHO-RAID
??
1. Switch on the Computer. Go to the BIOS Setup and enter the Standard
CMOS Setup. Set the HDD (the position of the SOHO-RAID) type on
AUTO, save and exit. The system will automatically detect the
SOHO-RAID.
2. After the boot-up is through, SOHO-RAID will start formatting and
Fdisk the Hard Drives.
SOHO -RAID User’s Manual

3. The next step will be the installation of the operation system and other
software required.
Install an original Hard Disk Drive which contains the system
??
software and data, and also a new Hard Drive into SOHO-RAID
1. Install a HDD tray with Hard Disk Drive, which contain system
software and data into either upper or lower HDD tray track of
SOHO-RAID before switch on the computer. The computer is bootable
now and the SOHO-RAID will work without the back-up function.
2. Then install a HDD tray containing a new Hard Disk Drive or a bigger
capacity Hard Disk Drive which with Data into another HDD tray track.
(Please notice the original data will be rewrite.) The SOHO-RAID will
start rebuilding and copying the contents of the original drive. When this
step is done, the SOHO-RAID is ready with the back -up function.
On-line Hot swap and Data Real-time automatic rebuilding
??
1. The SOHO-RAID alarm will sound when either Hard Drive fails. Pull
out the tray containing the defective hard disk drive and take it out.
2. The alarm will be stop, but the computer will keep on working with the
functional Hard Drive. Hence no data is lost.
3. Replace the defective hard disk drive (right away if the user has one at
hand) and plug the tray back.
4. All the above process can be done with the running continuously. A few
seconds later, the SOHO-RAID will start rebuilding data automatically.
(Please refer to INSTALLATION in Chapter 2, and also HDD Auto
Rebuild Function in Chapter 4.) Everything contained in the hard disk
drive will automatically be copied to the new hard disk drive.
