Important safety admonishments are used throughout this manual to warn of possible hazards to persons or equipment. An admonishment identifies a possible hazard and then explains what may happen if the hazard is not avoided. The admonishments — in the form of Dangers,

Warnings, and Cautions — must be followed at all times. These warnings are flagged by use of the triangular alert icon (seen below), and are listed in descending order of severity of injury or damage and likelihood of occurrence.

Danger

: Danger is used to indicate the presence of a hazard that will cause severe personal

injury, death, or substantial property damage if the hazard is not avoided.

Warning

: Warning is used to indicate the presence of a hazard that can cause severe

personal injury, death, or substantial property damage if the hazard is not avoided.

Caution

: Caution is used to indicate the presence of a hazard that will or can cause minor

personal injury or property damage if the hazard is not avoided.

1 GENERAL

This user manual describes the function and installation procedures for the ADC NGF Fiber

Optic Terminal Storage Bay.

The Next Generation Frame (NGF) Fiber Optic Terminal Storage Bay (FOTSB) is used as a storage apparatus for up to 16.4 feet (5 meters) of equipment (FOT) jumpers at the fiber frame lineup. The FOTSB can be installed between fiber frames within a lineup or between a fiber frame and an end guard at the end of a lineup.

The FOTSB is 7 feet high and 12 inches wide and is available for use with either the 24-inchdeep Fiber Main Distribution Frame (FMDF) or the 19-inch-deep Front Facing FMDF. The storage bay has vertical cable guides and spools for cable slack storage.

3 INSTALLATION

Warning

: Never install equipment in a wet location or during a lightning storm.

Installation of the storage bay is accomplished by securing the FOTSB to a frame or end guard within a frame lineup. Alternately, the bay can be secured to either a concrete or raised floor.

When attached to a frame, junction plates/spacer brackets are used. When attaching to an end guard, “L” mounting brackets are used.

Figure 2. Securing a Junction Plate/Spacer Bracket

3.1 Securing the Storage Bay to a Frame

Using the junction plates/spacer brackets, install the FOTSB as follows:

1. Align the holes in the junction plate/spacer bracket with the mounting holes in the storage bay ( Figure 2 ) and attach using two (2) #12-24 screws (provided). Repeat this step for each of the three sets of holes on this side of the bay. The mounting hole

locations are shown in Figure 3 .

Note

: Attaching a junction plate/spacer bracket in the lowest set of mounting holes is optional. The bay will be adequately secured using the upper and middle mounting holes only.

Note

: To access the lowest of the three sets of holes on the storage bay, it may be necessary to remove the rear kick plate. To do so, remove the four screws that secure the kick plate to the bay and replace after installing the bay to the frame.

2. Move the storage bay into position within the frame lineup.

3. Position the storage bay so that the empty holes in the junction plates are aligned with the mounting holes in the frame. Attach using two (2) #12-24 screws (provided) for each of the junction plates.

4. Repeat this process to secure the storage bay to a frame on the opposite side.

3.3 Concrete Floor Mounting

Ensure the appropriate hardware is available for concrete floor mounting. Typically four anchors are used when the FOTSB is floor supported. The anchor has a torque nut with a breakaway cap that breaks away when tightened to the proper torque pressure. Anchor the rack to the floor using the following procedures.

1. Position the bay in its designated floor location.

2. Mark the mounting hole locations on the floor. Use the holes with the widest spacing to provide the greatest stability. See Figure 5 .

Note

: To achieve maximum anchor-holding strength, select exact drill size for hole drilling.

3. Move the bay aside. At each mounting hole location, drill an 18 mm (.07 inch) diameter hole to a depth of 80 mm (3.15 inches) in the concrete. Clean out the hole with compressed air. Check the hole depth with a tape measure or by placing the assembled anchor bolts in each hole. If a reinforcing bar is encountered while drilling, relocate the hole. Fill the unusable hole with locally approved filling product.

3.4 Raised Floor Mounting

Various methods are used to mount equipment racks/bays to a raised floor. The method described here uses mounting hardware available in a kit from ADC. For other methods,

follow the instructions provided with that equipment. Table 1 lists the ADC kit contents. The

length of threaded rod required will depend on the raised floor height above the regular floor.

Ensure the appropriate hardware is available to satisfy raised floor mounting requirements. The following procedures cover a single storage bay placement. If more bays/racks in a line-up are being placed, the Unistrut lengths and positions of anchors in the lower floor must be adjusted accordingly. The anchor placed in the concrete floor is designed with a threaded stud and torque nut with a cap that will break away when tightened to the proper torque pressure. Prepare the raised floor support and anchoring hardware using the following procedures.

1. Position the storage bay in its designated floor location. Mark the mounting holes as

shown on the equipment rack footprint. See Figure 8 .

2. Move the bay aside. Drill four 16 mm (0.625 inch) clearance holes in the raised floor panel(s).

3. Remove any adjacent floor panels as needed to gain access to the lower floor.

4. Mark the lower floor in line with the holes in the raised floor panels. Use a plumb line or

equivalent for an accurate mark. See Figure 8 .

5. Draw an extended line through the centers of the mounting hole marks.

6. Cut two pieces of Unistrut into 36.0 inch (91.4 cm) lengths. Drill two 16 mm (0.625 inch) holes located 6.0 inches (15.2 cm) from each end.

7. Place the Unistrut on the lines made in step 5. Center along the line and mark the floor for the Unistrut anchor holes. Move the Unistrut out of the way for now.

8. Drill an 18 mm (.07 inch) diameter hole to a depth of 3.15 inches (80 mm) in the concrete at the marks made in step 7. Clean out the hole with compressed air. Check the hole depth with a tape measure or by placing an assembled anchor in each hole. If a reinforcing bar is encountered while drilling, relocate the hole. Fill the unusable hole with locally approved filling product.

9. Insert the anchors into each hole. Check that each anchor shoulder is even with the floor.

Use a deep socket or box-end wrench and tighten the torque nut until the anchor is just snug. Do not tighten until the torque nut cap breaks way. Repeat for each anchor. Refer

to Figure 9

10. Remove the nut and washer from the studs. Position the Unistrut over the studs. Replace the flat washer and torque nut onto the stud. Tighten the torque nut until the torque cap breaks away, indicating the anchor is properly set. Discard the break-away portion of the torque nut. Repeat for each anchor.

11. Insert spring-nuts into the Unistrut, aligning them with marks on the floor made in step 4.

See Figure 9 .

12. Replace as many floor panels as possible while still allowing access to the lower floor.

Position the equipment rack over the clearance holes in the floor panel.

13. Cut two lengths of Unistrut approximately 12.0 inches (30.5 cm) long. Mark the Unistrut at the hole positions of the raised floor made in step 2. Drill two 16 mm (0.625 inch) holes in the Unistrut.

14. Measure from the lower floor to the base of the equipment rack allowing sufficient length for leveling shims, hold down bar, washers, and nuts.

15. Place onto one end of the threaded rods, in order: 5/8-inch (16 mm) flat washer, 1/2-inch

(12.7 mm) flat washer, 1/2-inch (12.7 mm) lock washer, two - 1/2-inch (12.7 mm) hex nuts, 1/2-inch (12.7 mm) lock washer, 1/2-inch (12.7 mm) flat washer, 5/8-inch (16 mm) flat washer. On top of the pile up, place the shorter length Unistrut over the threaded rods.

You may find it easier to have someone hold the Unistrut beneath the raised floor panel for

step 16. See Figure 9 .

17. Thread the upper hex nut upward until the shorter Unistrut touches the bottom of the raised floor panel.

18. Place onto the upper end of the threaded rod (rack base end) the following items: 5/8-inch

(16 mm) flat washer, 1/2-inch (12.7 mm) flat washer, 1/2-inch (12.7 mm) lock washer, and 1/2-inch (12.7 mm) hex nut.

19. Align the equipment rack and tighten securely. Start with the floor Unistrut, then the

Unistrut under the raised floor and last the rack base.

3.5 Removing the Bend Radius Limiter

Removal of the bend radius limiters is recommended when using the FOTSB with a Next

Generation Frame that contains OSP cable. Removal of the radius limiters opens the vertical cable guides, which allows easier routing of OSP cable.

Perform the following procedure to remove the radius limiters:

1. Remove the two mounting screws that secure the vertical cable guide to the bay (

Figure 10

Set the screws aside.
