Introduction
SOHORAID (Redundant Arrays of Independent Drives) SR3500
provides disk mirror function (RAID Level 1) to secure data or RAID 0
to combine two drives’capacity for small offices or home offices.
SR3500 provides you the most economic and reliable external IDE
RAID subsystem connected with 1394a/1394b and USB2.0 interfaces
to expand capacity or ensure the data security for enjoying digital IT
network.

1-1Functions and Features
With individual microprocessor hardware RAID design, SR3500 is the
most economic and beneficial choice for you to expand capacity that
assure the data security and will not reduce system efficiency.
By connecting host interface of Firewire (1394a or 1394b) and USB 2.0
which enable SR3500 system not only easy to have the transfer rate
up to 50~80MB/sec but also plug and play function with double
advantages.
Human factor interface
※Plug & play
Designing for removable, easy installation and maintenance.
Using high quality stainless handle (SUS 302) for Removable.
Carrier to Hot plugto EIDE connector without interface card.
The two IDE hard disks can simultaneously perform mirroring or
RAID 0 with synchronization.
※Hot Swap Design
Once the hard disk failed, SR3500 allows replacement when the
system is online at RAID Level 1.
※Auto Rebuilding
One of the two hard disks can function as source, and the other
as target for back up purpose. Providing online rebuilding function
without gives any command and without interrupting system

operation at RAID Level 1.
※Duplication Hard Disk
SR3500 can also use as hard disk duplication, fit on the usage of
system duplicate and monitoring system offline data reserve at
RAID 1.
※Independent OS, Easy Installation
Compatible with all systems which support firewire (1394a or
1394b) and USB2.0 operation system like Windows 98 SE,
Windows Me, Windows XP, Windows 2000 and Mac 8.6 later.
※LCD (Liquid crystal display) Screen
LCD screen providing HDD operating status, Fan status, and
temperature status in order to monitor the system.

2-3 Environment Requirements and Cautions
1. Certainly, you can use two different drives in SR3500, but it will
get optimum performance and greatest convenience to use two
identical hard disks. We highly recommend using HDDs with the
same brand name at RAID 0 Mode.
2. We highly recommend you to decide the RAID Mode before
using SR3500. Unless you want to expand the capacity of
external hard disk, we recommend you to use the factory default
RAID 1 Mode for data security.
3. Use two hard disks in perfect conditions without any damaged
sectors with a minimum capacity of 3.2GB Ultra DMA 33/66.
4. No matter the primary or secondary disk, please set up both
Hard Disks in SR3500 to MASTER mode,or else HDD will not be
detected.

2-4 Installing HDD in the Carrier
ŸSet Master/Slave jumpers to MASTER (factory default).
ŸConnect the power cord and the Removable Carrier’s EIDE/IDE
interface cable to the HDD.
ŸInset the HDD into the Removable Carrier.
ŸFasten the HDD with the attached 6#-32 screws in their four
locations. Place the power cord and the EIDE/IDE interface cable
right than the surface of the HDD in order to avoid any hindrance
when taking out the HDD. Please refer to the following illustration.
