service enabled. Device can use two SIM cards, which can be used to make
connection to two different operators. Arctic 3G can be operated using only
one SIM card.
To operate with SIM card follow the procedure below:
1. Power off the Arctic.
2. The SIM card holder contains a tray with a yellow eject button. Push this
button to eject the tray from the holder.
3. Put the SIM card onto the tray.
4. Insert the tray carefully back to the holder and press the tray until it is
locked.
If two SIM card are used, repeat the procedure for SIM slot 2.
Note!
It is not recommended to insert or remove the SIM card while the Arctic 3G is
turned on.

3 Quick Installation
This chapter describes how to configure the WAN network interfaces on Arctic
3G.
3.1 Connection Principle
Arctic 3G has three network interfaces, Ethenet WAN, Mobile WAN (3G) and
Ethernet LAN. WAN interfaces are used for connecting Arctic 3G to public
Internet or private APN. Ethernet LAN is used for connecting other Ethernet
devices to Arctic 3G's local network.
WAN interfaces can be configured to get redundant system where one WAN
automatically gets traffic if the other one goes down. For example, if the
Ethernet LAN goes down, the traffic will be automatically switched to mobile
3G and back when the Ethernet interface comes up again. This way the
availability of the remote system will be better than with just one interface.
3.2 Connecting cables
1. Verify that the power switch is in the OFF position.
2. Connect the Ethernet cable between Arctic 3G (Ethernet LAN connector)
and your configuration computer.
3. Connect power supply to Arctic 3G and toggle power the switch to ON
position.
4. The error LED should turn on immediately after the power switch turned
on.
5. After the system has initialized, the Error LED turns off and the RUN LED
starts to blink.
3.3 Logging in to Arctic 3G
This section describes how to log in to Arctic 3G using web configuration
menu.

1. Configure your computer to use the same IP address space than Arctic 3G
(laptop IP for example 10.10.10.11 with netmask 255.0.0.0). Check with
ping command.
2. Connect to the Arctic 3G using your web browser. The default IP address
of Arctic 3G is 10.10.10.10 (netmask 255.0.0.0). Note that you have to
connect to a HTTPS port (see figure 13).
