NOTE No internal fusing is provided, because to do so would violate the specifications of
UL1459 section 70. (No fusing is allowed in the grounded side of a DC input circuit unless
the hot side is also fused.) When the fuse in the hot side blows, the fuse in the grounded
input must also blow. Since this equipment accepts either polarity, external circuit
protection must be provided in the hot side of the feeder circuit.
Setting Up the System
The following sections outline the procedures for installing, cabling, and
bringing up an AirLink Pro T1/E1 Rack Mount system. Some of the steps require
special knowledge, experience, tools, and assistance from another person.
Installing the Antenna
Antennas are generally installed by persons who have the knowledge,
experience, and tools to handle the somewhat specialized task. The following
sections are intended as a general summary of the process, and not as a complete
description. A successful antenna installation effort is the culmination of all
the site and route preparation, and path analysis.
Typical Antenna Mounts
An antenna for a microwave system such as the AirLink Pro T1/E1 Rack Mount
is typically equipped with mounting hardware that allows the antenna to
attach to a length of pipe that can then be mounted in several ways, depending
upon the user requirements, site conditions, and local building codes (see
Figure 2-3).
