 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 should have an unobstructed view of the sky overhead. The Extender 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 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’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

Certain information is necessary in an Extender other than the factory defaults that must be entered locally

using the command line interpreter (CLI). Please refer to the ―Trilliant Network Element Management System

(NEMS) Administration Guide‖ (Trilliant document number TLT-CS-ADM-94) for complete information.

They required information to be entered is:

 Netkey

 Management VLAN (if Management VLANs are used)

 VPN Shared secret (if using IPsec VPN. Please refer to Trilliant Technical Note ―Use of Virtual Private

Networking in the SecureMesh Communications Network‖, number DP-0906).

 The primary frequency should be configured to be the same as the Gateway to which it will connect.

The range of frequencies allowed for hunting is also appropriate to configure.
