Connections
If a NetBridge device is not working properly, first ensure that the unit has the proper
connections. The following needs to be connected to the NetBridge:
USB modem
A supported USB modem must be inserted into either the internal or external USB port. A
list of supported USB modems can be found at: http://acceleratedconcepts.com/support
The NetBridge device only operates with one USB modem at a time. Do not plug
in a USB modem into both the USB ports!
External USB Port
Internal USB Port

Ethernet Cable
An Ethernet cable is connected to both the Ethernet port on the NetBridge and the other end
device (client computer, AT&T VPN 8200, router, etc.). If the device is a router or AT&T
VPN 8200, the Ethernet cable should be inserted into either the Internet, WAN, or Uplink
port (see device’s manual).

Power
Power is supplied by either the 12-volt AC wall wart, 12-volt battery, or PoE cable.
The NetBridge device only operates with one supply of power.
oDO NOT supply power to the device with both the PoE cable and the 12-
volt battery/12-volt AC wall wart!
The 12-volt battery supplied with the NetBridge device typically has a life of 2-3
hours.
oThe 12-volt battery is not intended to be a permanent power source for
the unit. If the 12-volt battery is being utilized, ensure that the battery is
charged before use.

Ethernet
The NetBridge device is default configured for Auto-negotiation, but can be configured for a
different Ethernet negotiation setting. Below is a list of the Ethernet negotiation settings that
the NetBridge can be configured to.
10 Mbps Full Duplex
100 Mbps Full Duplex
10 Mbps Half Duplex
100 Mbps Full Duplex
Auto-negotiation
While in this setting, the NetBridge device communicates with the device connected
to the other end of the Ethernet cable and chooses the highest performance
transmission mode that both devices support. This is typically 100 Mbps Full Duplex.
Location
The placement of the NetBridge device at a site greatly affects the signal received from the
cellular network. To maximize signal strength, do the following:
Ensure that a cellular network tower is in the vicinity of the site where the NetBridge is
located. Contact your cellular provider for further information.
Place the NetBridge in an open space as far from the floor as possible within the site.
Ensure that the location where the unit is placed is free of electric noise (magnetic fields,
other cellular devices, etc.)
Do not place the NetBridge device in a metal enclosure! Also, ensure that there are no
other wireless communication devices (cell phones, wireless routers, etc.) within 1 ft. of
the NetBridge

Restore Default Settings
Restoring a NetBridge device to factory default settings will clear out the settings
obtained from the NetBridge’s remote configuration and load the factory default
settings. To restore a NetBridge device back to default settings, perform the following
steps:
1. Power off the NetBridge for at least two seconds.
2. Remove all USB devices from the NetBridge.
3. Use the four rubber feet screws to remove the case of the NetBridge.
4. Power on the NetBridge and wait 30 seconds for the device to complete startup.
a. Note: at this point the only light that should be illuminated is a red USB LED.
5. Press the “Default configuration” button located on the circuit board of the
NetBridge. The default configuration button is located above the “Restart” button,
next to the coin cell battery.
6. Once the Default configuration button is pressed, ensure that the USB and Wireless
LEDs of the NetBridge are alternately flashing red and green. This indicates that
the NetBridge is applying the default configuration.
7. Wait for the NetBridge to reboot and apply the changes. Once the USB LED
illuminates red and all other lights are off, it is safe to power off the NetBridge, re-
attach the case, and reconnect any USB devices.

Start-up
The NetBridge device is configured to go through a specific start-up sequence, as detailed
below.
1. Immediately upon powering on, the USB LED will illuminate YELLOW, verifying that
power is being delivered to the NetBridge. The USB LED should immediately turn BLUE
for two seconds, YELLOW for one second, GREEN for one second, and settle on RED.
This indicates that the NetBridge successfully booted up and is waiting for the USB
modem to be initialized (if connected).
2. Approximately 10 seconds after power up, the USB, Wireless, and signal strength LEDs
will illuminate in a pattern corresponding to the LEDs section of this Troubleshooting
Guide.
LEDs
The NetBridge has lights on the front panel that help an installer or end user to discern the
current status. The USB and Wireless LEDs are labeled; the bars outlined in orange are the
signal strength indicator. These lights usually indicate the state of their respective
subsystems. Some light patterns represent the whole system state instead of a subsystem.
The icons in the chart represent the state of the lights. Black ( ) indicates an off light.
White ( ) indicates that the light is irrelevant in a pattern –these continue to show their
own subsystem status. Multicolored symbols indicate a changing light.
Examples:
The Wireless light blinks red/off/green/off. The other lights can be any
color.
The Wireless light flashes amber twice. The other lights can be any
color.
The USB and Wireless lights are blinking red/green in opposite order.

Known Issues
The NetBridge has the following known issues:
Coin Cell Battery
The NetBridge’s internal clock is powered by the coin cell battery located on the circuit
board of the device. If this battery is damaged or dies, this will cause an error in the
system where the NetBridge’s internal clock is unusable. This causes the NetBridge to
freeze during boot. The following process can be used to determine if this issue is
present:
1. Power on the NetBridge.
2. Watch the USB LED of the NetBridge. If the internal clock of the NetBridge is
unusable, the USB LED will continuously loop, displaying a pattern of illuminating
yellow, blue, yellow, green; meanwhile, all other LEDs of the NetBridge will remain
off.
To resolve this issue, perform the following steps:
1. Power off the NetBridge.
2. Use the four rubber feet screws to remove the case of the NetBridge.
3. Remove the coin cell battery from the battery holder located on the NetBridge circuit
board next to the Restart and Default configuration buttons.
4. (Optional) Insert a new 3V coin cell battery into the NetBridge.
a. Note: If a working coin cell battery is not connected to the NetBridge, it will
not be able to save its date/time over reboots. However, this will not affect
overall performance, so it is safe to leave the coin cell battery out.
5. Re-attach the NetBridge case.
6. Power the NetBridge on and verify that it boots properly.
