For your protection, please read all these instructions regarding your Cobalt NASRaQª
and retain for future reference.
Read Instructions
All the safety and operating instructions should be read and understood before the
appliance is operated.
Ventilation
The Cobalt NASRaQ Ôs vents (on the front) and the fan opening (on the back panel) are
provided for ventilation and reliable operation of the product and to protect it from
overheating. These openings must not be blocked or covered. This product should not be
placed in a built-in installation unless proper ventilation is provided.
Lithium Battery
The lithium battery on the system board provides power for the real-time clock and CMOS
RAM. The battery has an estimated useful life expectancy of 5 to 10 years. If your system no
longer keeps accurate time and date settings, it may be time to change the battery. Contact
Cobalt for service information. No operator serviceable parts inside.
Warning: There is a danger of explosion if the battery is incorrectly
replaced or replaced with the wrong type of battery. Replace only with
the same or equivalent type recommended by the equipment
manufacturer. Dispose of used batteries according to manufacturer’s
instructions.
Attention: Il y a danger d’explosion s’il a remplacement incorrect de la
betterie. Remplacer uniquement avec une batterie du meme type ou
d’un type equivalent recommande par le constructeur. Mettre au rebut
les batteries usagées conformement aux instructions du fabricant.
Achtung: Explosionsgefahr wenn die Battery in umgekehrter Polaritat
eingesetzt wird. Nur mit einem gleichen oder ahnlichen, vom Hersteller
empfohlenen Typ, ersetzen.Verbrauchte Batterien mussen per den
Instructionen des Herstellers verwertet werden.

Setting Up the NASRaQ
This chapter is intended for the NASRaQ administrator and
describes connecting and conÞguring the NASRaQ for your
network.
If the NASRaQ has been previously conÞgured for a different
network, refer to ÒChanging Network ConÞgurationÓ on
page 42.
The setup process includes the following steps:
¥ ÒEstablishing a ConnectionÓ on page 7 discusses the
physical setup and connection of the NASRaQ to a power
source and the network.
¥ ÒSetting Up With the Web BrowserÓ on page 14 covers
the network integration process and allows the
administrator to select services and create users and
groups using any browser-enabled computer.
Establishing a Connection
Connecting the NASRaQ includes the following procedures:
¥ Installing the NASRaQ
¥ Connecting to the network
¥ Connecting the power cord
¥ Powering on the NASRaQ
¥ ConÞguring DHCP and manual network settings
Installing the NASRaQ
The NASRaQ can either be placed on a ßat surface Ñ for
example, a desk, shelf, or table top Ñ or it can be installed in
an equipment rack.

!
Caution:If you operate the NASRaQ in an equipment rack, see
the precautions described in “Using Equipment Racks” on
page iv.
If you plan to use the NASRaQ on a ßat surface, attach the
rubber feet to the Þve indentations in the bottom of the case.
Figure 1 Attaching rubber feet
If you plan to operate the NASRaQ in an equipment rack,
Þrst connect the mounting ears to the sides of the NASRaQ
(as shown in Figure 2) near either the front or the rear of the
case. Ensure the supporting lip is placed under the unit to
provide additional support and attach the ears to the
equipment rack.

Connecting to the Network
Connect one end of a Category 5 Ethernet cable to the 10/100
Base-T network connector on the back of the NASRaQ (see
Figure 3). Connect the other end to an existing network
socket.
Figure 3 NASRaQ Rear View
Connecting the Power Cord
Connect the power supply cord to an electrical outlet (100-
240 volts AC, 50/60 Hz, as listed in ÒProduct SpeciÞcationsÓ
on page 45).
Powering On the NASRaQ
Turn on the power by pressing the On/Off switch on the back
of the NASRaQ.
The hard disk starts up, the fan turns on, and the LCD screen
lights up and displays the message
Starting Up
.
Status messages are displayed on the LCD screen as the
NASRaQ completes its boot process.
!
Caution: It’s important to follow the proper power-down
procedure before turning off the NASRaQ. Refer to “Powering
Down” on page 43.

Configuring the Network
Now that youÕve made the network and power connections,
youÕre ready to conÞgure the network settings.
The NASRaQ requires speciÞc network information to
properly function. The information can be entered
automatically or manually.
Depending on the network environment, the NASRaQ may
be able to obtain the necessary information from a DHCP
server on your network. If so, it will attempt an automatic
conÞguration. If not, you need to enter the necessary
information manually, using the LCD console on the front
panel. See ÒUsing the LCD Console to ConÞgure the
NetworkÓ on page 11 for more information.
Automatic Configuration using a DHCP Server
When the NASRaQ is powered on, it checks to see whether a
DHCP server is present on the network. If thereÕs a
functioning DHCP server thatÕs set up to serve leased IP
addresses, the NASRaQ conÞgures itself automatically.
If the network information can be conÞgured automatically,
the LCD displays the NASRaQÕs assigned IP Address upon
completion of the boot process.
IMPORTANT:To function properly over long periods of time, the
NASRaQ’s IP address must remain the same, i.e., the DHCP
server must not assign it to a different machine at a later date.
Unfortunately, some DHCP servers do not honor requests for
permanent IP addresses.As a result, the system or network
administrator may need to assign a different (and permanent)
IP address to the NASRaQ. If so, change the network
configuration information.You should coordinate any changes
to the IP address, subnet mask, or gateway address with your
network administrator.
