Important
Notice Due to the nature of wireless communications, transmission and reception of data can
never be guaranteed. Data may be delayed, corrupted (i.e., have errors) or be totally
lost. Although significant delays or losses of data are rare when wireless devices such
as the Sierra Wireless modem are used in a normal manner with a well-constructed
network, the Sierra Wireless modem should not be used in situations where failure to
transmit or receive data could result in damage of any kind to the user or any other
party, including but not limited to personal injury, death, or loss of property. Sierra
Wireless accepts no responsibility for damages of any kind resulting from delays or
errors in data transmitted or received using the Sierra Wireless modem, or for failure
of the Sierra Wireless modem to transmit or receive such data.
Safety and
Hazards Do not operate the Sierra Wireless modem in areas where blasting is in progress,
where explosive atmospheres may be present, near medical equipment, near life
support equipment, or any equipment which may be susceptible to any form of radio
interference. In such areas, the Sierra Wireless modem MUST BE POWERED OFF.
The Sierra Wireless modem can transmit signals that could interfere with this
equipment.
Do not operate the Sierra Wireless modem in any aircraft, whether the aircraft is on
the ground or in flight. In aircraft, the Sierra Wireless modem MUST BE POWERED
OFF. When operating, the Sierra Wireless modem can transmit signals that could
interfere with various onboard systems.
Note: Some airlines may permit the use of cellular phones while the aircraft is on the ground
and the door is open. Sierra Wireless modems may be used at this time.
The driver or operator of any vehicle should not operate the Sierra Wireless modem
while in control of a vehicle. Doing so will detract from the driver or operator's control
and operation of that vehicle. In some states and provinces, operating such
communications devices while in control of a vehicle is an offence.

1: Overview
This document provides operation and configuration instructions for the oMG running
software version 3.14.
1.1 Who Should Read This Guide
IT specialists who configure and oversee usage of the oMG should read this guide.
This guide contains common configuration tasks, while the appendices contain
detailed information on the available configuration options.
1.2 What is the oMG
The oMG is a ruggedized wireless gateway, designed for use in harsh mobile and
portable environments. The gateway extends the utility and convenience of LAN
networking to devices and applications in vehicles. The oMG interfaces with the AMM,
Sierra Wireless’ mobile network management system.
Figure 1-1: The back panel of an oMG
Key Features of the oMG:
•works in conjunction with the AMM to transmit data such as GPS, telemetry,
GPIO, and asset tracking information
•supports customization through the installation of select applications (purchased
separately) which tailor the unit to the needs of a fleet
•supports a variety of network interfaces including Ethernet, USB, Bluetooth,
Serial, a wide range of 802.11 WiFi/frequencies, 3G cellular networks, and LTE
networks
•supports network redundancy through multiple network interface installations

Overview
Rev 4 May.17 9
•supports DHCP and static IPs
•provides high security through technologies like ESP, authentication,
encryption, firewall etc.
•supports VLANs and VPNs
1.3 Pre-Installation Requirements
This manual assumes that the appropriate cellular modem card is already
installed in the oMG base unit and that the cellular network provider has activated
the card.
In some cases, the cellular modem card may be pre-installed at the factory prior
to shipping. If a network card must be installed, please read the oMG Installation
and Configuration Guide for your model of oMG.

2: Powering the oMG On and Off
2.1 Powering On
The oMG has a factory default configuration that enables it to establish a WAN
connection if a cellular modem is installed along with an appropriate SIM card, and
the APN is configured correctly. Note that additional configuration is always
recommended.
Start the unit using the following steps:
1. Apply power to the system: if the oMG has been installed and wired into a
vehicle’s electrical system, turn on the ignition. If the oMG is not in a vehicle, an
optional AC power adaptor can also be used to supply 12V-DC power to the
system.
2. Turn on the unit: by default the oMG should start up automatically once it receives
power. If it does not, press the reset button on the back of the unit. Once power
up is complete the amber and green LED's will remain solid. For more information
on the LED patterns see LED Blink Patterns on page 99.
3. Test the unit: connect a test device such as a PC, equipped with Ethernet or WiFi,
to the oMG LAN. An oMG with factory default settings will provide an unsecured
WiFi access point (AP) broadcasting its own Serial Number as the SSID (e.g.
H100109D0002) and will also provide LAN access using Ethernet ports 1 to 3. 1
Once these steps have been completed, the oMG is ready for use, however further
configuration of the unit should be performed using the sections provided in this
document.
2.2 Powering Off
When powering down the unit, ensure that at least three minutes have elapsed since
the unit’s green Status light began to blink or at least two minutes have elapsed since
the light went solid.
This is necessary to ensure proper preparation of configuration files, in particular,
upon the first boot after a factory reset which takes longer than normal to prepare
these files. If this process is interrupted by a premature shutdown and/or removal of
power from the oMG, the process will repeat on subsequent boots until it is
successfully completed.

3: Accessing the Configuration Settings
The oMG Local Configuration Interface (LCI) is the oMG's browser-based
configuration utility which organizes the various configuration pages under a series of
tabs and sub tabs.
To access the LCI, navigate to the following URL using a web browser:
http://welcome.to.inmotion/MG-LCI. If this URL is not reachable, try entering:
172.22.0.1/MG-LCI. This will display the LCI login screen:
Figure 3-1: LCI Login Panel
Note: Configuration of the unit is best performed using a web browser running on a Windows 7
or Windows XP PC. As of version 3.8, the oMG supports Internet Explorer 9. Other devices and
other browsers may work but have not been certified by Sierra Wireless.
Log in using the following default credentials:
•User Name: admin
•Password: admin
Most configuration settings take effect immediately. However those related to the use
of the serial port only take effect after reboot.
The browser’s Forward and Back arrows can be used to navigate through the LCI.
Note that unless the Save button is clicked after making configuration changes, the
changes will not be saved and applied.

3.1 Viewing the Configuration Settings
The oMG includes an Easy Access page, which allows users on all devices
connected to the unit to view the unit’s operational status without having to log
into the unit.
To view the Easy Access page from a device (e.g. laptop) connected to the unit,
navigate to the following URL using a web browser:
http://welcome.to.inmotion/MG-LCI/easyaccess.html.
This will display a read-only page showing the oMG’s operational status:

4: Preparing the Network Interfaces
By default the oMG comes pre configured with devices which can provide both WAN
and LAN connectivity. It's recommended that the settings for each device be verified
before using the oMG. This will help to ensure that each device has been recognized
by the system and is properly configured to provide LAN or WAN data
communications.
To view device settings, navigate to the Devices tab in the LCI:
Figure 4-1: An example of a Cellular Device on the Device Configuration Tab
A custom/descriptive name can be entered into the Friendly Name field. This can be
useful for example, to identify which access point the device will be used for.
Access the sub tabs to set each of the networking devices available on the oMG for
WAN or LAN usage:
•Cellular: cellular connectivity is the most common method for accessing the WAN
when an oMG is outside of a depot. Verify that the Installed field is checked for
each device listed on the Cellular tab and that the Use field has been set to WAN
for at least one of the devices listed.
•Ethernet: verify that the Installed field is checked for each Ethernet port listed.

5: Setting up the WAN
The oMG can access a WAN through cellular, WiFi, and wired Ethernet
connection(s). Cellular WAN access is the most common method while the oMG is
travelling in a vehicle and WiFi WAN access is often used when a vehicle returns to a
depot where an AP is available for the oMG to connect to as a client. By default,
Ethernet Port 4 is configured for WAN access, while ports 1 to 3 are configured for
LAN access. While the Ethernet ports can be used for WAN access, they are more
commonly used for providing connectivity to devices on the oMG's LAN.
Multiple devices can also be configured to provide redundant WAN access should one
connection go down.
Note: The oMG does not support USB-to-Ethernet adapters for WAN operation.
5.1 Basic WAN Link Configuration
Each device which has been enabled for WAN connectivity (as described in Preparing
the Network Interfaces on page 13) will be listed as a WAN link, configurable under
the WAN > Links tab.
To configure how these links provide WAN access:
1. Navigate to the WAN > Links tab.
2. Click Configure in the Actions column for a link:
Figure 5-1: WAN Link Tab
The following subsections provide an overview of the configuration for the most
common WAN links.

Setting up the WAN
Rev 4 May.17 15
5.1.1 Cellular WAN Link Configuration
Cellular WAN is the most common type of WAN connection used on the oMG
because it provides connectivity from wherever cellular reception is available. This
type of link requires that a cellular card be installed in the oMG with a pre-
authorized cellular data plan from your Mobile Network Operator.
Configuration settings are specific to each type of cellular card installed, however
typical settings can include a dial string, user ID/password, and modem
initialization.
The screenshot below shows the cellular configuration settings for a Sierra
Wireless Aircard:
Figure 5-2: Common Cellular WAN Link Configuration Settings
Tip: Always test the cell card in a laptop with the APN before using it in the oMG, to
ensure the card has been properly configured.
Additional information on common cellular settings is available in Cellular WAN
Link Configuration Settings on page 68. For more information on specific settings
for your card contact your Mobile Network Operator or Sierra Wireless Technical
Support (see Contact Information on page 3).

5.1.2 WiFi WAN Link Configuration
A WiFi link provides WAN access to the oMG via a WiFi AP which is often
available in locations such as vehicle depots. Since it's usually preferable to utilize
an AP when available, WiFi links are usually configured as the primary WAN
access method on the oMG.
The following screenshot shows the settings for a WiFi WAN link configuration:
Figure 5-3: WiFi WAN Link Configuration
Additional details on these settings are available in WiFi Link Configuration
Settings on page 71.
Once a WiFi WAN link has been configured it must then be assigned to an AP
profile which stores credential and other information required to communicate
with an AP. The creation of an AP profile and its assignment to a WiFi link is
described in Defining an Access Point Profile for WiFi Links on page 18.
5.1.3 Ethernet WAN Link Configuration
An Ethernet (wired) connection can also be used to provide WAN access to the
oMG, though this is less common since the main purpose of the oMG is to
provide mobile WAN access using wireless methods.

Configuration Settings on page 72.
5.1.4 Serial WAN Link Configuration
A serial modem can be connected to the serial port and will have a Device Type
of TTY Serial Port on the Serial Modem device listing screen.

The following screenshot shows the settings for a serial modem WAN link:
Figure 5-5: Serial WAN Link Configuration
For more information see TTY Serial Port Link Configuration Settings on page 74.
5.2 Defining an Access Point Profile for
WiFi Links
An AP profile must be created for each WiFi AP that an oMG will use to access
the WAN. A profile creates an association between the actual AP and the
credentials (i.e. access, security, etc) required to connect to that AP from the
oMG. The settings for a profile must therefore match those defined at the actual
WiFi AP itself.
To define an AP profile:
1. Navigate to WAN > WiFi Networks, click Add New WiFi Network. The WiFi
Network Configuration page will be shown.
2. Configure the AP profile settings based on how they are configured in the
actual AP itself. Information about these settings can be found in WiFi
Networks Configuration on page 76.
3. Click Save to save the AP profile settings.
4. Set the WiFi link to use the WiFi AP profile:
a. Locate the WiFi link under WAN > Links.

Note: If multiple WiFi access points have been defined, each access point will be listed
and available for selection in the WiFi link's configuration settings.
5.3 Maintaining Communications with
Services of a WAN
The oMG can use a monitor to detect and try to recover from "high level"
communication failures occurring on a healthy connection between a WAN link
and a LAN segment (e.g. server timeouts due to a server being rebooted). A
monitor accomplishes detection and recovery by periodically checking against its
preconfigured parameters for problems such as a minimum number of connection
failures, timeouts, etc.
Using a monitor helps to ensure that communication sessions between devices
connected to the oMG's LAN, and services or hosts being accessed over the
WAN, are maintained and reestablished if possible.
It's highly recommended that a monitor be created and configured for cellular
devices.
Note: Currently, the only supported monitoring method is ICMP ping monitoring.

Operation and Configuration Guide 3.14
20 4118618
Note: A monitor cannot be used for detecting "low level" communication problems such as
the loss of WAN connectivity (e.g. loss of cellular reception). These types of problems must
be dealt with using the oMG's WAN recovery feature as described in Recovering from
Dead WAN Connections on page 31.
To create or modify a monitor:
1. Navigate to WAN > Monitors.
2. Click the Add New WAN Monitor button to create a new monitor, or click on
Configure in the Actions column to modify an existing monitor.
3. Modify the monitor settings as required to detect a dead connection, ensuring
that the correct LAN segment is selected for the Source Address field. See
WAN Monitor Settings on page 76 for information on specific settings.
4. Click Save to save the monitor configuration.
5. Enable the monitor for a link:
a. If configuring a cellular or Ethernet link, enable the monitor on the link as
follows:
i. Navigate to WAN > Links, select the link to assign a monitor to and
click Configure.
ii. Locate and enable the Monitor in the link's Monitors settings.
iii. Click Save to save the link configuration.
b. If configuring a WiFi Link, enable the monitor in the AP profile assigned to
the link:
i. (Optional) Identify the AP profile assigned to the WiFi link if not
already identified, from under the WiFi Networks option in the link's
configuration settings:
