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.

User Guide
• Simple administration—You can run the browser-based management interface from any computer in
your network, and its informative wizards and configuration pages will help you accomplish your tasks
quickly and easily.
• Status at a glance—The home page of the management interface lets you quickly determine how
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 sockets, 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: Refer to your printer’s documentation for information about disabling duplex communication.
With some duplex printers, printing might complete successfully, although errors might
occur. In addition, some features (such as the printer reporting low ink levels) might not
function since two-way communication is not supported.

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.
For more information about this step, see “Creating Shared Folders” on page 33.
5. Access the shared folders.
For information about this step, see “Accessing Shared Folders” on page 37.
6. Protect your computer hard disks.
This process involves installing DiskSafe Express on each computer that you want to protect and
specifying which hard disks or partitions to back up and how often backups should occur.

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 system 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.
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 performance.
Getting Started - 13

User Guide
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

Serial ATA 4-Drive NAS
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.
User Guide
If you have four disks that are not the same size and you intend to use RAID 10, USRobotics recommends that you load the disks in ascending order of disk capacity, starting with the smallest disk in the
bottom slot (slot 1),
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.
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.
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.
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.

Serial ATA 4-Drive NAS
User Guide
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.
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.
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.

click Finish.
Caution: If you reduce the recommended amount of space to use for backups, you might
not be able to back up as many disks or use the maximum allowed number of
backup versions. The recommended amount of space is greater than the total size
of all your disks to accommodate multiple backup versions.
If you change these proportions after you finish the wizard, you will lose all data in
your shared folders and all existing backups.
Backup of computer disks is provided through a separate backup and recovery utility. You can install
DiskSafe Express from the USRobotics Installation CD-ROM for this purpose. For more information
about DiskSafe Express, see the “Protecting Local Disks” on page 77.

User Guide
to use a specific IP address, you might need to specify the IP address of the gateway in your network
before you can successfully access the Web User Interface using a Web browser. First access the Web
User Interface using the Storage System Console and then specify the gateway address (as described in
“Changing the Network Settings” on page 64.) and try to access it using a Web browser.
Using the Storage System Console, you can access the Web User Interface only from a computer in the
same subnet as the storage system, but you do not have to know the name or IP address of the storage
system or otherwise modify the network settings.
Note: The Storage System Console launches a Web browser, so the computer where you install the
Storage System Console must have Microsoft Internet Explorer 6.0 or Firefox 1.06 or newer
installed as well.
Accessing the Web User Interface Using a Web browser
To access the Web User Interface using a Web browser:
1. From any computer in your network, run Microsoft Internet Explorer 6.0 or Firefox 1.06 or newer, enter
the following in the address bar, and then press Enter:
http://storage_system
where storage_system is the name or IP address of the storage system.
Note: You can use the storage system name only if that name is registered with a DNS server on
your network.
When the login page appears, you can bookmark it so that you can quickly and easily access it the
next time.
2. Log in to the Web User Interface (as described in “Logging In to the Web User Interface” on page 26).
Accessing the Web User Interface Using the Storage System Console
If you want to access the Web User Interface using the Storage System Console, you must install the
Storage System Console on each computer from which you plan to manage the storage system. You can
install the Storage System Console on any computer that runs one of the following operating systems:

Adding Users
By default, the storage system includes a user named guest that has a password of guest. However, you
might want to add other users as well. For example, if you want to restrict access to a shared folder that
contains confidential information, you would add at least one user and authorize that user to access that
shared folder (and not authorize the guest user to access it). Adding a user for each individual or computer
in your network provides maximum flexibility and security, enabling you to control exactly who can access
what information.
In addition, only Windows and Mac OS X users can use the guest user name. If there are Linux users or
Mac users who aren’t using OS X in your network, you must add users to allow those individuals to access
any shared folders.
When you add a Windows or Mac OS X user, a folder with the same name as that person’s user name is
automatically created on the storage system. Only that person can access that folder, and that person has
full read/write access to it. (In the Storage System Console, this folder is identified as the home folder.)
You can add up to 64 Windows or Mac OS X users, and up to 64 Linux or other Mac users (for a total of up
to 128 users).
Note: Since each Linux/other Mac user can represent multiple users, the number of actual users can
be higher.
To add a user:
