1Introduction
This user manual describes the features and how to configure a Virtual Access GW7304
Series router.
The Virtual Access GW7304 Series router is ruggedized and supports extended
temperature, high isolation and protection levels. The router enclosure is not conductive.
It has 8 Ethernet ports, 3G radio access modems, with up to two SIM cards and a serial
console access. There are AC and DC power versions. It implements general purpose
rouer features such as dynamic routing protocols (OSPF and RIP), VPN and DMVPN,
IPSec, VLANs, GRE tunnels, DHCP server client and relay, TFTP, 3G access, CLI and web
access.
1.1 Document scope
This document covers the following models in the GW7304 Series.
GW7304-3G-AC 8 x Ethernet ports, dual SIM, 1 x RS232, 3G wireless WAN connection, Internal PSU,
AC power input, 2 x antenna SMA connectors
GW7304-3G-DC 8 x Ethernet ports, dual SIM, 1 x RS232, 3G wireless WAN connection, Internal PSU,
DC power input, 2 x antenna SMA connectors
1.2 Using this documentation
You can configure your router using either the router’s web interface or via the command
line using UCI commands. Each chapter explains first the web interface settings,
followed by how to configure the router using UCI. The web interface screens are shown
along with a path to the screen for example, ‘In the top menu, select Service ->
SNMP.’ followed by a screen grab.
After the screen grab there is an information table that describes each of the screen’s
fields.
1.2.1 Information tables
We use information tables to show the different ways to configure the router using the
router’s web and command line. The left-hand column shows three options:
•Web:refers the command on the router’s web page,
•UCI:shows the specific UCI command, and
•Opt: shows the package option.
The right-hand column shows a description field that describes the feature’s field or
command and shows any options for that feature.
Some features have a drop-down menu and the options are described in a table within
the description column. The default value is shown in a grey cell.
Values for enabling and disabling a feature are varied throughout the web interface, for
example, 1/0; Yes/No; True/False; check/uncheck a radio button. In the table
descriptions, we use 0to denote Disable and 1to denote Enable.

Some configuration sections can be defined more than once. An example of this is the
routing table where multiple routes can exist and all are named ‘route’. For these
sections, the UCI command will have a code value [0] or [x] (where x is the section
number) to identify the section.
Web Field/UCI/Package Option
Description
Web: Metric
UCI: network.@route[0].metric
Opt: metric
Specifies the route metric to use.
Note: these sections can be given a label for identification when using UCI or package
options.
network.@route[0]=route
network.@route[0].metric=0
can be witten as:
network.routename=route
network.routename.metric=0
However the documentation usually assumes that a section label is not configured.
The table below shows fields from a variety of chapters to illustrate the explanations
above.
Web Field/UCI/Package Option
Description
Web: Enable
UCI: cesop.main.enable
Opt: enable

link by mitigating problems associated with multipath interference.
2.8 Components
To enable and configure connections on your GW7304 Series router, it must be correctly
installed.
The GW7304 Series router contains an internal web server that you use for
configurations. Before you can access the internal web server and start the
configuration, ensure the components are correctly connected and that your PC has the
correct networking setup.
The GW7304 Series router comes with the following components as standard.
1 x GW7304 Series router supplied.
1 x Ethernet cable supplied. RJ45 connector at both ends.
1 x rubber right angle antenna standard supplied.

2.9.2 Mounting the GW7304 on a DIN rail
The GW7304 Series router is supplied with a DIN rail clip attached.
Offer the GW7304 Series unit down on to the DIN rail. Hold the unit at a
slight angle and slide the top teeth of the DIN rail clip down onto the DIN
Rail.
When the top teeth and DIN rail are connected, push the unit down and
back in one motion until the DIN rail clip clicks into the DIN rail.
The click sound means the box has engaged on the DIN rail and is secure.

2.9.6 Connecting the antenna
Virtual Access offers a variety of antennas as every 3G/4G wireless deployment is
different. When selecting an antenna for your device, you should consider factors such
as the installation environment, mounting options and the distance between router and
antenna location.
If you are only connecting one antenna, screw the antenna into the MAIN SMA
connector.
If you are using two antennas, screw the main antenna into the MAIN SMA connector
and the secondary antenna into the AUX SMA connector.

2.9.10 Recovery mode
Recovery mode is a fail-safe mode where the router can load a default configuration
from the routers firmware. If your router goes into recovery mode, all config files are
kept intact. After the next reboot, the router will revert to the previous config file.
You can use recovery mode to manipulate the config files, but should only be used if all
other configs files are corrupt. If your router has entered recovery mode, contact your
local reseller for access information.
