Installing Fiber Cables

2.11If you purchased a “bare” wall box and now need to instal l the fiber cables, install the angled retainers and adapters one at a time in the vertical bulkhead plate in the front section of the wall box. The right side of each adapter should be pointing downward. Terminate the connectors to the left side of the adapters, then route the fiber cable(s) clockwise around the four radius limiters in the left side of the wall box as shown in Figure 4. Route the stub ends of the cables into one of the splice trays.

Grounding Kit

2.12Each grounding kit for the wall box consists of a 12-inch length of AWG #6 stranded wire with a #6 ring terminal, together with a #6 - 14 lug connector and a shield connector. The grounding kits are to be used for grounding OSP cables to the ground stud assemblies previously installed on the rear panel of the wall box. If an OSP cable has a grounding tab, connect it to the nearest ground stud (Figure 5) using the grounding kit.

Fiber Designation Labels

2.13Two sheets of labels are provided with the wall box. Use the Brady labels to mark the stub ends of individual OSP cable fibers. The strip labels on the other sheet can be put on the inside of the left front cover of the wall box (as shown in Figure 10) to identify the destinations of the 36 patch cords.

D. Replacement Procedure — Key Locks

2.14Each front cover of the wall box has a key lock for security. Use the following procedure to replace the key locks:

1.From inside the front cover, remove the lock nut that holds the key lock to the cover (see Figure 1).

2.Remove the key lock from the front of the cover.

Note: Install the replacement key lock so the “teeth” of the key will be down in the locked position; furthermore, the lock on the right should open when turned clockwise, and the lock on the left should open when turned counterclockwise.

3.While the key lock is in the “locked” position (i.e., pointing straight up), insert the key lock through the cutout; then install and tighten the lock nut while keeping the locking tab pointing straight up (i.e., in the 12 o’clock position).

4.Operate the key lock several times to ensure that it operates correctly (i.e., that the left key lock opens when the key is turned counterclockwise and the right key lock opens when the key is turned clockwise).
