The maximum data transfer speed, in practice, is
depending on the setup of the local cellular network, the
distance to the nearest base station, the cell size, the level
of utilization of the network and so on.

Remote management helps with the
administrative tasks and is essential with the
devices that are located at remote sites
•
Management can be implemented via VPN

Extra ground connection
•
The operating voltage, 12-30
Volts DC is connected via
power connector that can be
fastened with screws
•
The power supply is optional
accessory, Viola Systems
order code 3020, with
universal 100-240VAC IEC
input
•
The previous power supply
model (order code 3010) with
two-pin connector can also be
used, the extra ground is left
unconnected
DIN rail attachment
•
Arctic 3G has grooves for optional
DIN rail mounting brackets.
•
Mounting accessories include
two DIN rail mounting brackets
and four screws. (In picture
product 2620, the 2622 mounting
brackets are different)
•
The brackets can be installed
horisontally or vertically to
the bottom of the Arctic 3G
gateway.
This allows wide variety of
installation positions.

SIM card insertion
1. Turn off the unit
2. Insert the SIM card into the slot so that the contacts are
facing down and the notched corner is facing out
3. Gently push the card into the slot with pointy object, e.g.
with an unfolded paper clip
4. The card is in place when the notch of the card is inside
the slot and behind the spring lever
SIM card removal
• To remove the SIM card from
the slot, press the small lever
in front of the SIM card ’s
notched corner. Push from up
to down; not from outwards to
inwards
Ethernet ports
• There are four Ethernet ports in the device.
Ports are compatible with IEEE 802.3i (10BASE-T) and
IEEE 802.3x (100BASE-TX)
• The WAN port is for connecting upstream towards
gateway to internet. If Arctic is directly connected to a
computer via WAN port, a cross cable is needed
• The LAN ports support MDI/MDIX detection, i.e. both
cross connected and straight connected cables can be
used
• WAN and LAN ports can be interchanged

Slide 1/4
• There are three serial ports in the device.
• RS1 port is for RS-232/RS-422/RS-485
connectivity
• RS2 port is for RS-232 connectivity only
• In addition to the two RS-ports, the console
port is also connected with RS-232. It is
differentiated from the RS1/RS2-ports by the
connector type, which is RJ-45.

Q: My Firefox browser warns about possible security problem
when I try to connect to the Arctic 3G GW’s graphical user
interface. Should I be worried?
A: There is nothing to be worried about in this case. The
certificate is signed by Viola Systems Ltd. This certificate is not
among the trusted certificates in browser. You can safely add a
security exception as in the pictures below.
