The standard 23-inch equipment frame has equal anges, measures 7 ft high, and can hold up to eight FDC
units (Figure 2). The Universal Distribution Frame (UDF) has unequal anges.
Figure 2
Equipment frame extensions are available to bring the
total height of the FDF to 9 ft and 11.5 ft (Figure 2). The 9-ft
frame allows two more housings to be installed and the
11.5-ft frame holds ve more housings.
End caps for the FDF increase the dimensions by 3 inches
per end cap. To add more frames, remove the end caps (see
Figure 12) and bolt the new frames in place.
Interbay Storage Units (IBU) are used between frames to
route and manage jumpers on front of the FDF. The IBUs
have nine routing hubs, a top jumper trough, and a jumper
trough bridge (Figure 3). Do not coil bers around a hub.
Refer to the instruction provided with the IBU for more
detailed assembly instructions.

a. Locate the frames over the oor holes.
b. Secure them to each other using nuts and bolts through
the uprights on the frames.
c. Install the oor mounting bolts and tighten.
Step 2: If the installation requires the frame to be supported from
the top, use a 1/2-in diameter J-bolt or threaded rod (not
supplied) and secure the frame to the overhead support
(Figure 7) using the washer and nut. Attach the top
supports so they run perpendicular to the frame. This will
provide clear space for cable routing.
Step 3: Attach the foot cap assembly as shown in Figure 8.

NOTE: Install an electrical outlet into the foot cap, if
necessary. Knock-outs are provided in the foot
cap panels and the base of the end cap to route
the power cables.
a. Remove the outlet cover.
b. Install the electrical outlet into the cut-out in
the foot cap. Secure the outlet to the foot cap
using the mounting plate and screws provided
with the outlet (Figure 9).
c. Attach the foot cap to the frame.
Step 4: If a frame extension is required, install it
now using the provided hardware. Use the
carpenter’s square to square the extension
with the frame. Figure 9
NOTE: When the FDF will be secured to an overhead support structure (Figure 6), use a 1/2 -in diameter J-bolt or
threaded rod (purchased separately).
7. Grounding the Frame
Step 1: Determine the location on the frame where the ground
wire (purchased separately) will be attached. Scrape o
paint from this location of the frame to ensure metal-to-
metal contact.
Step 2: Attach a #6 AWG copper ground wire and ground lug
together.
Step 3: Screw the ground lug directly into the frame using 12-
24X1/4 screws (Figure 9).
Step 4: Attach the grounding wire to the building ground
by crimping the C-tap around the two grounds and
connecting them together.
NOTE: In a line-up of more than one frame, use the extra ground
lug that is included in the kit. Attach the ground lugs to the
frames and then attach the ground wire to both frames.
Figure 10

8. Install Jumper Troughs
Jumper troughs (Figure 11) are designed to hold ber
optic cables running from one FDF to another and
are attached to the frame in three places at regular
intervals. The troughs are 4 1/2 inches deep and
facilitate the running of bers when more than one
FDF is connected side-by-side. Jumper troughs are not
required when running jumpers to adjacent housings;
in this case, jumpers are routed through the housings.
Use jumper troughs to route jumpers around rather
than through housings. Attach jumper troughs as
shown in Figure 11. Use the top and bottom troughs
to service the two top and bottom housings. Use the
center trough to service the remaining housings.
• On a 7-ft frame, use a large trough at
the bottom of the frame and a standard
trough at the top and center.
• On a 9-ft frame, use a large trough at the
top and bottom and a standard trough in
the center.
• On an 11.5-ft. frame, use three large
troughs.

9. Install End Caps
End caps (Figure 12) provide protection for the end of each row of bays. End caps are not required between the
frames in the row.
Figure 12
10. Housing Installation
10.1 Attach Fiber Routing Guides
Attach ber routing guides to the housings before the housings are installed into the frame to provide bend
radius control and organization (Figure 13). Several types are available.
Figure 13
NOTE: The routing guides are designed to allow the separation of vertical and horizontal runs in a single frame.
Do not wrap a jumper completely around a routing guide. This may violate the ber’s recommended
bend radius and degrade its transmission characteristics. Always leave sucient slack.

10.3 Attach Labels
Attach labels as shown in Figure 14.
1. Attach a trough label to each
jumper trough.
2. Attach bay identication labels
to the foot cap or at the top of
the bay.
3. Attach routing guide labels to
either side of the housings near
the guides.

11. Jumper Installation
11.1 Connector Cleaning
IMPORTANT: To protect connector connector end faces from damage and dirt, leave the protective covers (dust
caps) on the jumpers until ready to plug into adapters. Obey the following precautions in order not
to damage the surface of the connector and make it unusable:
WARNING: Never look directly into the end of a ber that may be carrying laser light. Laser light can
be invisible and can damage your eyes. Viewing it directly does not cause pain. The iris of the eye will
not close involuntarily as when viewing a bright light. Consequently, serious damage to the retina
of the eye is possible. Should accidental eye exposure to laser light be suspected, arrange for an eye
examination immediately.
WARNING: DO NOT use magniers in the presence of laser radiation. Diused laser light can cause
eye damage if focused with optical instruments. Should accidental eye exposure to laser light be
suspected, arrange for an eye examination immediately.
WARNING: Isopropyl alcohol is ammable with a ashpoint at 54°F. It can cause irritation to eyes on
contact. In case of contact, ush eyes with water for at least 15 minutes. Inhalation of vapors irritates
the respiratory tract. Exposure to high concentrations has a narcotic eect, producing symptoms of
dizziness, drowsiness, headache, staggering, unconsciousness, and possibly death.

• Always keep dust caps on connectors and adapters when not in use.
• Ensure dust caps are clean before reuse.
• Use optical cleaning materials as standardized by your company.
• Clean the connector before every mating, especially for test equipment patch cords (jumpers).
• A minimum level of cleaning is listed below. Local procedures may require more rigorous cleaning
methods.
Step 1: Remove plugs from the connector adapter.
Step 2: Wipe the connector ferrule twice with a lint-free wiping material moistened with isopropyl alcohol.
Then wipe across the end of the ferrule.
Step 3: Repeat previous step with a dry wipe.
11.2 Installing Jumpers
CAUTION: Fiber optic cable is sensitive to excessive pulling, bending, and crushing forces. Consult the
cable specication sheet for the cable you are installing. Do not bend the cable more sharply than the
minimum recommended bend radius. Do not apply more pulling force to the cable than specied. Do
not crush the cable or allow it to kink. Doing so may cause damage that can alter the transmission
characteristics of the cable; the cable may have to be replaced.
To install a jumper, rst identify the two ports to be connected.
a. Select a jumper length based on Table 1 and Figure 11.
b. Remove the dust cap from each connector and mate with their appropriate adapters.
c. Route the jumper per previous instruction in sections 10.3 and 10.4.
d. Use the nearest available IBU to store jumper slack.
NOTE: It is important to use proper methods when removing jumpers from a populated bay line-up to prevent
temporary attenuation or permanent damage to the jumper being removed and the other jumpers in the
routing pathways.
11.3 Removing Jumpers
To properly remove a jumper, rst identify the rst end to be disconnected.
a. Unplug the rst connector, taking care not to disturb adjacent connections, and place a dust cap on
the connector to prevent damage to the connector endface. Also, place a dust cap on the exposed
adapter to prevent dirt from entering the adapter alignment sleeve.
b. Carefully feed the jumper out of the housing and trace the jumper back through the routing
pathways. Be careful not to snag, pull or bend any of the surrounding jumpers.
c. Once the second end of the jumper has been reached, unplug the connection and place a dust cap on
the connector and the exposed adapter.
12. Fiber Management
12.1 Attach Cable Tie Brackets
FDF cable tie brackets are provided to maintain an organized
installation by grouping cables at the rear of the frame
together. Attach the brackets to the frame as shown in
Figure 15 using the provided hardware.

12.2 Routing in a Single Frame
• When routing to the left or right side of a single frame, use the Interbay Storage Unit (IBU) to store
jumper slack.
• When routing from an upper quadrant of one side of a frame to either quadrant of the opposite
side of the frame, route to the top of the frame to traverse to the opposite side and route back
down to the correct housing.
• When routing from a lower quadrant of one side of a frame to either quadrant of the opposite side
of the frame, route to the lower jumper trough to traverse to the opposite side of the frame and
route up to the correct housing.
12.3 Routing in a Multiple-Frame Line-Up
• When routing from quadrants on the shared sides of adjacent frames, route directly from housing
to housing and store excess jumper slack in the IBU.
• When routing from upper quadrants to any quadrant on anther frame, route to the upper jumper
trough to traverse to the appropriate frame. Route down to the appropriate side frame and into
the correct housing.
• When routing from lower quadrants to any quadrant on anther frame, route to the lower jumper
trough to traverse to the appropriate frame. Route up to the appropriate side frame and into the
correct housing using the nearest IBU to store any jumper slack.
13. Door Installation
Doors (purchased separately) are available for the FDF frame (Figure16).
Refer to SRP 003-242 provided with the doors for detailed assembly
instructions.
14. Maintenance
The unit requires very little maintenance to make sure bers and parts
remain in good condition.
Loose Parts: Check nuts, bolts and screws for looseness and tighten.
Moisture: Check the housings for accumulated moisture and place moisture
absorbent packets as needed.
Fiber Bends: Check ber optic cable to make sure bends do not exceed the
minimum bend radius. Check cable for unnecessary strain. Check cable
entries and exits for crimping or crushing.
Documentation: Check record label to make sure it is clear and accurate.
