4 DIGITAL HOST UNIT INSTALLATION PROCEDURE

This section provides the installation procedures for the DHU. Installation of the DEU(s) and

DRU(s) may proceed separately from the installation of the DHU. The installation procedures

for the DEU are provided in the Digital Expansion Unit Installation Instructions (ADCP -75-

111) which are shipped with the DEU. The installation procedures for the DRU, the DRU

antennas, and the AC/DC converter (optional DRU accessory) are provided in the Digital

Remote Unit Installation Instructions (ADCP-75-112) which are shipped with the DRU. When

all units of the Digivance ICS have been installed, refer to Section 5 of this manual for the

system power up and test procedures.

4.1 System Plan Review and Pre-Installation Cable Routing

Before beginning the installation, review the system plan with the system engineer. Make sure

each equipment installation site is identified and located and all cable runs are mapped out.

The coaxial, DC power, and fiber optic cables may be routed between the various equipment

locations before the equipment is installed. Whenever possible, route fiber optic cables

through conduit or a guideway such as the FiberGuide system. Avoid routing fibers through

ladder type cable racks or troughs that do not provide sufficient support to limit bending or

prevent accidental damage. Tie-wrapping is not recommended as a means of securing fiber

optic cables. Make sure to leave sufficient slack at each equipment location for connectorizing

and cable management. The procedures for terminating the cables and for connecting the

cables to the DHU are provided in the sections that follow.
