1.2 Unpacking and Inspection

This section provides instructions for opening the shipping boxes, verifying that all parts have

been received, and verifying that no shipping damage has occurred. Use the following

procedure to unpack and inspect the HU and any accessories:

1. Open the shipping cartons and carefully unpack each component from the protective

packing material.

2. Check each component for broken or missing parts. If there are damages, contact ADC

(see section 6 at the end of this manual) for an RMA (Return Material Authorization) and

to reorder if replacement is required.

2 FIBER OPTIC CABLE ROUTING AND INSTALLATION GUIDELINES

The outside plant (OSP) fiber optic cables should be routed between the HU and RU and

terminated before the equipment is installed. A diagram of a typical fiber optic cable routing is

shown in Figure 3-1. At the HU, the OSP cable should be terminated at a fiber distribution panel

and spliced to pigtails. Patch cords may then be used to link the HU optical ports to the OSP

cable terminations. Whenever possible, a guideway such as the FiberGuide system should be

provided to protect the fiber optic patch cords from damage and to prevent excessive bending.

The procedures for connecting the OSP cable optical fibers to the HU is provided in Section 7.
