Introducing Your Storage System
The Serial ATA 4-Drive NAS is an intelligent network storage solution for small and medium-sized offices
and home network environments. It provides up to 2.0 TB of hard disk space for both shared files and
backups of your computer hard disks, offering an ideal way to distribute and protect important data.
To make it easy to back up your computer hard disks, this solution includes DiskSafe Express, a software
application that provides reliable data protection and rapid data recovery in the event of a system crash or
disk failure. With DiskSafe Express, you can recover your local disks or partitions without having to reinstall
or reconfigure the operating system or applications, dramatically shortening recovery time.

System Requirements
• Microsoft Windows XP; Microsoft Windows Server 2003; or Microsoft Windows 2000 Professional,
Server, or Advanced Server with Service Pack 4
• An HTML 4.01-compliant Web Browser (such as Internet Explorer 5.5 or later or Netscape 8.0 or later)
with JavaScript enabled
Key Features and Benefits
•Flexible storage capacity—The storage system supports up to four 3.5" SATA-I hard disks, with a
capacity of 80–500 GB each. You can start with just one and add more as your needs grow.
•Built-in data protection—In addition to a linear disk configuration in which all the disks are treated as
independent entities, the storage system supports several different types of RAIDs (redundant arrays
of independent disks). This means that you can take advantage of the build-in data protection and data
duplication offered by advanced RAID levels. If your storage system has multiple hard disks and one
fails, you won’t lose important data. For more information, refer to "Disk Configurations," beginning on
page 107.

much space is being used and who’s currently connected.
•Support for multiple platforms—Whether the computers in your network run Windows, Mac OS X or
other Mac operating systems, or Linux, you can set up file sharing for each of them.
•Security—Only authorized users can access the shared folders on your storage system. You can also
control whether the user can only view the information in the shared folders or also add, modify, or
delete files there.
•Fast performance—With its gigabit Ethernet support, the storage system provides fast access to the
data you need, when you need it.
•Printer support—You can attach up to two pass-through printers to the storage system’s USB sock-
ets, and all users can access them.

USB Printer Limitations
The storage system is designed to work with up to two USB printers. However, the following are not
supported:
• Multi-function printers (such as printers that perform copying, scanning, or faxing in addition to printing)
• Windows Printing System (WPS)
• Non-PostScript printing (Mac)
• Duplex-only (two-way) communication
Note: If the temperature of the entire unit reaches or exceeds 85º C (185º F) or if the temperature if any
of the disks reaches or exceeds 55º C (131º F), the storage system shuts down automatically.
If the temperature of any of the disks reaches or exceeds 42º C (107.6º F), the fan will run at full speed.
If the temperature of any of the disks reaches or falls below 37º C (98.6º F), the fan will slow down.
Operating System Linux Kernel 2.6
Network Service DHCP client/server (default IP address is 192.168.0.101)
Supported Web Browsers • Microsoft Internet Explorer 6.0
• Firefox 1.06 or newer
RAID • Standard RAID 0
•RAID1
•RAID5
•RAID5+spare

Getting Started - 11
Getting Started
Getting started with your storage system involves the following general steps:
1. Install your storage system.
This process involves installing both the hardware and software components of your storage system
and specifying the initial configuration.
For step-by-step instructions for this process, see “Installing Your Storage System”.
2. After installation is complete and the storage system restarts, start the Web User Interface and log in.
For more information about this step, see “Accessing the Web User Interface” on page 24.
3. Add users.
If you want to control access to the shared folders, or if the users in your network use Linux or Macs
that don’t use OS X, you must create a list of users.
For more information about this step, see “Adding Users” on page 30.
4. Create shared folders.
By default, the storage system includes a shared folder named public, which all Windows and Mac OS
X users can access. However, you might want to create other shared folders as well. For example, in
an office environment, you might want to create a shared folder for company policies that everyone
can view, and separate folders for confidential business documents that only selected individuals can
view or change. In a home environment, you might want to set up separate folders for different types of
files, like photos, videos, or music.

considerations, see “Step One: Determine Your Configuration” on page 12.
2. Set up your storage system.
This involves installing the hard disks, attaching any optional USB devices, attaching the storage sys-
tem to your network, and powering up the system.
For information about this step, see “Step Two: Set up Your storage system” on page 13.
3. Install the Storage System Console.
You will need the Storage System Console to initialize your hard disks in step 4.
For information about this step, see “Step Three: Install the Storage System Console” on page 16
4. Initialize the Hard Disks.
This step loads firmware from the storage unit’s memory to each disk. “Step Four: Initialize the Hard
Disks” on page 17.
5. Configure your storage system.
Before you can use your storage system, you must perform some initial configuration tasks, like setting
the date and time, and specifying how much space to use for file sharing and how much to use for
backups. The System Setup wizard guides you through this process.
For information about this step, see “Step Five: Configure your Storage System” on page 20.
If you bought your Serial ATA 4-Drive NAS with the disks already installed and configured, and you do not
want to change your disk configuration, skip step one and proceed with “Attaching USB Devices” in step
two on page 15.
Step One: Determine Your Configuration
Before you start the physical installation of your storage system, decide which configuration is best suited
to your needs. The configuration that you choose may affect the order in which you load the disks into your
storage system, and you will need to specify your configuration choice when you reach “Step Five:
Configure your Storage System”.
Each supported configuration has a different balance of desirable characteristics, as shown in the table
below. The configurations available to you depend on the number of disks installed in your storage system.
Use this table to select your configuration based on the number of disks you intend to use and the
characteristics that are of the highest priority to you.

Step Two: Set up Your storage system
Setting up your storage system consists of the following steps:
Installing the Hard Disks
Attaching USB Devices
Connecting the Storage System to the Network
Powering Up the Storage System
Installing the Hard Disks
If you have fewer than four hard disks in your storage system, you might want to add more at this time. You
can add disks later, but changing your disk configuration once the disks contain data might cause data
loss.

* Available capacity based on 500-GB drives
Note: The storage system must have at least one SATA hard disk with a capacity of at least 80
GB.
USRobotics strongly recommends that you install all the hard disks that you want to use in
the storage system at this time in order to avoid data loss.
USRobotics also recommends that you use 4 disks of the same size for optimum perfor-
mance.

To install the hard disks, you need a Phillips head screwdriver.
1. Remove the top hard disk tray from the storage system:
2. Near the front of the tray is a spacer containing four screws. Squeeze the tabs together to remove the
spacer from the tray.
3. With the flat edge of the spacer up and the screws facing a flat surface (such as a table or desk top),
flex the sides of the spacer apart from each other to release the screws.
4. Make sure that the hard disk is a SATA disk. It should have a SATA connector similar to the following:
5. Slide the new hard disk into the tray (connector end down and toward the back of the tray), and fasten

the screws on the sides of the tray:
6. Slide the hard disk and tray back into the storage system until it snaps into place.
If you have fewer than four disks, load the bottom trays first and leave the top tray or trays empty.
If you have four disks that are not the same size and you intend to use RAID 10, USRobotics recom-
mends that you load the disks in ascending order of disk capacity, starting with the smallest disk in the
bottom slot (slot 1),
For more information about disk configurations, see the “Disk Configurations” on page 107.
7. Repeat steps 1 through 6 for each disk that you will use in your storage system.
Attaching USB Devices
If you have USB storage devices or printers, you can attach them to the USB ports on the back of the
storage system.
Connecting the Storage System to the Network
To connect your storage system to your network, insert one end of the supplied RJ-45 Ethernet cable into
the Ethernet port on the back of the storage system. Then insert the other end into a network port.
Notes:
• If you install a hard disk that was previously part of a RAID, it will rebuild automatically.
• If you later replace all of the disks with higher-capacity disks, you will have to format
those disks.
Note: USB hubs are not supported. In addition, any USB disk must be formatted before you use
it with the storage system, and only the first partition of a FAT or FAT32 file system will be
recognized. Do not attach the storage system directly to a USB port on a computer.

Powering Up the Storage System
To power up the storage system, insert the power cable into the power connector on the back of the
storage system and plug the other end into a power outlet.
Once you have connected the power cable, make sure that the power switch on the back of the storage
system is set to the on position. Then press and release the power button on the front of the storage
system.
The power and Disk LEDs flash while the storage system is booting. Once the system has finished
booting, the Disk LEDs stop flashing.
If the hard disk installation was successful, the Disk LED is blue. If there is a problem, the Disk LED is off.
If this occurs, shut down the system, remove and inspect the hard disk for any installation problem, and
reinstall it. To shut down the system, press and hold the power button for approximately five seconds until
the Disk LEDs start flashing. Then release the power button; the storage system will shut down after a
short period.
Step Three: Install the Storage System Console
Install the Storage System Console on a computer on the same network as the Serial ATA 4-Drive NAS:
1. Insert the USRobotics Installation CD-ROM into your CD-ROM drive.
2. If prompted, select your preferred language, then review the License Agreement and click Yes.
The installation CD prompts you to make a choice:
3. Select Console Installation.
Note: USRobotics recommends that you plug the storage system into a surge protector or
uninterruptible power supply to prevent damage to the system from power surges.
