Firmware Version 3.1.5 16 Document Version 1.0

3 Quick Installation

3.1 Connection Principle

The Arctic has configurable network interfaces, Ethernet WAN or Ethernet
LAN port for a cable network, and Mobile WAN for wireless communication.
The WAN interfaces are used for connecting the Arctic to public Internet or
private APN. Ethernet LAN is used for connecting other Ethernet devices to
the Arctic's local network.

The 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
primary Ethernet connection goes down, the traffic is automatically switched
to mobile WAN (secondary connection) and back when the Ethernet interface
comes up again. This way the availability of the remote system is 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 (Ethernet LAN connector) and

the computer used for the configuration.

3. Connect power supply to Arctic and toggle the power switch to ON

position.

4. The power/error LED and function LED should turn on immediately after

the power switch is turned on.

5. After the system has initialized, the function LED starts to blink.

3.3 Logging in to Arctic

This section describes how to log in to Arctic using web configuration menu.

Figure 13. Ethernet WAN configuration

Connectivity Monitor settings are used when WAN redundancy functionality is
required. Monitor keeps checking the connection to the given remote host to
determine the network status. If the ping does not get an answer for a given
time window, it informs the WAN switch logic to try the secondary interface.

If the WAN redundancy is implemented by using two separated Ethernet
connections with different gateways, the Backup Gateway parameter needs

User's Manual
Arctic Communication Gateway

Firmware Version 3.1.5 22 Document Version 1.0

to be configured towards the correct backup gateway. Backup Gateway
parameter is not needed if WAN redundancy is implemented with wireless
connection.

See section WAN Failover and backup routing settings on page 23 for
more details about WAN redundancy.

4.1.3 Mobile WAN

This screen configures the Mobile WAN interface on the Arctic. The
configuration screen fields are described below.

PIN code The 2G/3G/LTE cellular networks use a

SIM card. The SIM card can be protected
by PIN code (personal identification
number). If the PIN code is used, it
must be entered to Arctic’s Mobile WAN
settings. Leave the PIN code field empty
if no PIN code is used. If a wrong PIN
code is entered, correct the code and
enter the correct PIN code to the SIM by
using a mobile phone.

APN Type By default automatic APN discovery is

used. Arctic tries default APN values
based on network ID received from
cellular network. If automatic settings do
not work, set to APN Type parameter
from Automatic to Manual.

APN The APN parameter defines the cellular

access point name. If APN Type is set
to Manual the access point works as
a gateway from the cellular network to
internet. There are public and private
access points. A public access point is
usually defined. A private access point
requires contract with a cellular operator.
Viola M2M solution is compatible with
both public and private access points.
Define the access point name as
according to information received from
the cellular operator.

Authentication, username, password If the cellular network requires

authentication for using the access
point, the access point’s username
and password need to be defined
in the Arctic. In this case, select the
authentication type (PAP, password
authentication protocol or CHAP,
challenge handshake authentication
protocol) as according to information
received from the cellular operator.

DNS selection, DNS servers Allows user defined DNS servers,

receiving DNS server IP addresses
from cellular network or leaving DNS
configuration as disabled. The DNS

5.2 Configuring serial gateway

This section describes how to configure serial <-> IP functionality.
The serial gateway feature enables data from the serial port attached device

to be routed to Ethernet/mobile network (serial over IP) and vice versa. Serial
gateway processes the transmitted data transparently and does not alter it
any way except for buffering it for transmission. Because of the transparent
communication, any protocols can be used in actual communication between
nodes.

Figure 20. Serial gateway configuration screen

Serial gateway configuration depends on used protocols.
