Storage
The NAS supplies you with the following media storage:
■ CD drive
■ High-capacity Serial-ATA hard drive
CD drive
The CD drive lets you access data on CDs. The drive cannot read DVDs or burn
CD-Rs or CD-RWs.
To insert a CD into the CD drive:
1 Press the eject button located on the front of the CD drive. The disc tray
opens.
2 Place the CD onto the disc tray. Make sure that the label or title side of
the disc is facing upward.
WarningH old the di sc by the edge s to avoid leaving smudges or
3 Slide the disc tray into the NAS until it clicks into place.

fingerprints.
www.gateway.com
Caring for y our CDs
■ Keep your CDs in a CD case when not in use to avoid scratches or other
damage. Any kind of dirt or damage can affect the data on the disc or stop
the drive from successfully reading the disc.
■ When handling discs, always hold them by the edges to avoid smudges
or fingerprints.
■ When cleaning discs, use a clean, dust-free cloth and wipe in a straight
line from the center to the edge. Do not wipe in a circular motion.
■ Clean your CD drive periodically.
Hard drive
Your NAS came installed with four hot-swap hard drives. By default, the NAS
is configured with the RAID (redundant array of independent disks)
configurations, either RAID 0 (striped), RAID 1 (mirrored), or RAID 5 (striped
with parity).
The NAS uses a Promise PDC20275 IDE controller to support the ATA/133
channel and a high-performance ARC600-66 IDE RAID controller with four
Marvell 8818030 bridges to support the four hot-swap SATA hard drives.
Storage
When correctly configured, the NAS ca n pro vide non-stop ser v ice with a high
degree of fault tolerance through the use of RAID technology and advanced
array management features. The hard drive can be configured to RAID levels
0, 1 (0+1), 5, and 10.
www.gateway.com
11
Chapter 1: Overview
Hardware RAID lay out
The NAS is recognized by the host computer’s operating system as two logical
drives. The two logical drives are configured to RAID levels 0+1 and 5. The
system volume, installed with the host operating system, is organized as
RAID 0+1 and the data volume is organized as RAID 5.
The volume layout for the NAS is illustrated below.
Disk 1Disk 2Disk 3Disk 4
V olume configuration
The organized volumes on the NAS include:
Raid 5
Raid 0
Raid 1Raid 1
12
■ System vol ume
This volume is organized as a RAID 0+1 volume. This volume includes the
operating system image. The default size for thi s v olume is 10 GB. Use the
RAID Volume Configuration utility to configure the size. For more
information on how to use the RAID Volume Configuration utility, see
“RAID Configuration” on page 54.
■ Data volume
The remaining hard drive space is organized as the data volume using
RAID 5. For a NAS installed with four 120 GB hard drives, the data volume
size can be set to 345 GB.
www.gateway.com
RAID volume computation
Depending on the hard drive capacity, the system volume and data volume
capacity can have different sizes. A simple formula to calculate dat a volume
size per RAID level is shown in the table below (where SSV is the size of the
system’s volume in gigabytes):
Refer to the following table for changing the data volume of your hard drive
or changing the default configuration setting according to your data volume
size preference:

Chapter 2: Setting Up
Requirements
Selecting a site
Before unpacking and installing the NAS, select a suitable installation site for
maximum efficiency. Consider the following factors when choosing a site:
■ Near a grounded power outlet
■ Clean and dust-free
■ Sturdy surface free from vibration
■ Well-ventilated an d away from sources of heat
■ Protected from electromagneti c fields prod uced by electrical d evices such
as air conditioners and rad io and TV transmitters.
ImportantIf your installation calls for placement on table top, install
the supplied rubber feet on the bottom of the chassis. For
more information, see “Installin g on a table t op” on
page 19.
Warnings
■ Do not attempt to modify or use the supplied AC power cord if it is not
the exact type required. A product with more than one power supply will
have a separate AC power cord for ea ch supply.
■ The power button on the NAS does not turn off AC power. To remove the
AC power from the NAS, you must unplug the AC power cord from the
wall outlet or power supply. The power cord is considered the disc onnect
device to the main (AC) power. The socket outlet that the NAS plugs into
should be installed near the equipment and should be easily accessible.

Cabinet installation tec hnical details
T ake note of the following information when pl anning wher e and how to install
the NAS:
Ambient temperature
The maximum operating temperature of the NAS is 95°F (35°C) and the
relative humidity of the NAS is in the range 20% to 80% (non-condensing).
Careful consideration should be given to installing the NAS in an
environment compatible with 95°F (35°C) maximum ambient
temperature.
Height and weight
Before installing the NAS, make sure that the surface on which you are
setting it is strong enough to bear its weight and accommodate its size.
Weight (approx imately, depend ing on con figurat ion): 42 lbs. (19 kg)
Requirements
Rack mounting
When mounting your NAS into a cabinet (equipment rack), make sure you
maintain correct mechanical load leveling to avoid hazardous conditions.
Po wer source
The NAS should be operated using only the type of power source indicated on
the product label.
■ Voltage: 100-240 V
■ Current: 6 A
■ Frequency: 50/60 Hz

Chapter 2: Setting Up
Circuit o verloading
Appropriate consideration should be give n when co nnecting the supp ly circuit
to the NAS to avoid any circuit overload. The system nameplate rating should
be used when addressing concerns about circuit overload.
WarningMake sure that the site has the necessary capacity to
Reliable grounding
To avoid the potential for an electrical shock hazard, the rack assembly itself
must be suitably grounded, according to your local regional electrical codes.
This typically will require the rack to have its own separate ground. We
recommend you consult your local approved electrician.
Electrical shock
Do not operate the NAS unit without the top cover in place. Opening or
removing the cover may expose you to dangerous voltage and can cause
electrical shock.
handle the NAS. Overloading electrical supply circuits is
extremely hazardous.
Battery precautions
There may be a danger of explosion if the CMOS battery is incorrectly replaced.
Replace this battery with model CR2032 only. Use of another battery may
present a risk of fire or explosion. Dispose of used batteries according to
manufacturer's instructions.
Sufficient ventilation
The vents on the front panel an d the fan openings on th e rear panel provide
ventilation for the NAS. Make sure that these openings are not blocked and
that adequate ventilation is provided where the unit is installed.

Cabinet installation precautions
Before installing the NAS, take the following precautions:
■ The NAS is heavy. To minimize the chances of injuries, make sure that two
or more people help in installing the NAS.
■ Do not place heavy objects on the NAS.
■ Before installing, mark its intended position in the rack with a felt-tip pen .
Mounting the NAS so it is not level could result in malfunctions.
■ If you attach the two mounting ears in the forward position on each side
of the NAS, make sure that you use a four-point mounting configuration.
Do not use a two-point mounting configuration.
