Extender Bridge Installation Guide
Trilliant Incorporated page 9 of 26
The Extender Bridge enclosure must be mounted at least 18 feet (5.5 meters) above ground level,
although radio performance and coverage will generally improve as the mounting height is increased.
The installation location must not obstruct radio communications. For example:
The mounting structure should not block radio coverage or be adjacent to structures that block
radio coverage).
The installation location must be clear of thick trees or brush growth upon installation and in the
foreseeable future. Foliage in the line of sight with other communicating devices can
detrimentally affect radio performance.
The Extender Bridge should have an unobstructed view of the sky overhead. The Extender
Bridge relies upon GPS (Global Positioning System) signals to establish time synchronization,
and the strongest GPS signals are available if the device has an unobstructed view of the sky.
Upon startup, the Extender Bridge searches for a GPS signal. If the device cannot detect a
signal, it will be unable to complete startup and will not establish wireless connections with other
SecureMesh WAN devices.
As necessary, adequate space must be available to use a bucket truck.
The installation location must not impede normal maintenance activities (for example, access to the
Extender Bridge’s associated Power Service Unit to replace the battery).
If choosing a streetlight pole installation, make sure the streetlight is providing constant power.
Pre-Provisioning
In general, each Extender Bridge is shipped from the factory with most utility-specific configuration items
already written into non-volatile memory. However, certain information must still be configured prior to
installation.
Provide power to the Extender Bridge, and then configure parameters associated with both Extender and
Collector functionality.
Extender Parameters
To configure the Extender Bridge’s Extender parameters, connect the Extender Bridge to an Ethernet network,
establish a Telnet session to IP address 192.168.0.2 to access the Extender Bridge’s Extender functionality,
and invoke the command line interpreter. Please refer to the SecureMesh WAN Command-Line Interface
(Trilliant document number DP-0985) for complete information.
The following Extender parameter must be configured:
Shared network key (“netkey”) the shared network key is used by a SecureMesh WAN node to
prove (via an authentication handshake) that the node belongs to a particular network or operator; i.e.,
the shared network key is used to authenticate the SecureMesh WAN node to the SecureMesh WAN
and, reciprocally, authenticate the SecureMesh WAN to the SecureMesh WAN node. The netkey is a
string of 6 to 64 ASCII letters, numbers, or symbols.
If IPsec VPNs are being used (and Trilliant strongly recommends their use), the following Extender parameter
must also be configured:
VPN credentials the VPN shared secret allows a SecureMesh WAN management tunnel to be
established to the VPN router (note that in automatic provisioning mode, node configuration is provided
