EH450 Quick Start Guide

Introduction

Welcome to the Quick Start Guide for the EH450 Hot Standby Base /

Repeater Station. This section provides additional step-by-step

instructions to install, commission and operate the EH450 Hot

Standby Base Station. This document should be read in conjunction

with the EB450 Base Station Quick Start Guide.

The EH450 is a fully redundant, hot standby digital data radio base /

repeater station providing automatic changeover facilities.

The EH450 is designed as a modular solution, comprising 2 identical

EB450 base station units (standard) linked to a central, fail-safe

monitoring and changeover controller (Hot Standby Controller). Either

base station may be taken out for maintenance without the need for

any system down time. The automatic changeover is triggered by out

of tolerance (alarm) conditions based on either RF and/or user data

throughput parameters.
