ADMONISHMENTS
Important safety admonishments are used in this manual to warn of possible hazards to persons or equipment. The admonishments — in the form of Dangers, Warnings, and Cautions — must be followed at all times. These warnings are flagged by use of a triangular alert icon (shown 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.
GENERAL SAFETY PRECAUTIONS
Danger: Infrared radiation is invisible and can seriously damage the retina of the eye. Do not look into the ends of any optical fiber. Do not look directly into the optical adapters of the adapter packs. Exposure to invisible laser radiation may result. An optical power meter should be used to verify active fibers. A protective cap or hood MUST be immediately placed over any radiating adapter or optical fiber connector to avoid the potential of dangerous amounts of radiation exposure. This practice also prevents dirt particles from entering the adapter or connector .

6 INSTALLING AND ROUTING CABLES
Danger: Infrared radiation is invisible and can seriously damage the retina of the eye. Do not look into the ends of any optical fiber. Do not look directly into the optical adapters of the adapter packs. Exposure to invisible laser radiation may result. An optical power meter should be used to verify active fibers. A protective cap or hood MUST be immediately placed over any radiating adapter or optical fiber connector to avoid the potential of dangerous amounts of radiation exposure. This practice also prevents dirt particles from entering the adapter or connector .
Caution: Placing a load in excess of 5 pounds (2.3 kg) onto an open tray will result in misalignment or damage to the tray.
6.1
Routing and Securing Cables
The FMT may be configured to provide termination and storage, storage only, or termination and splice functions. For each configuration, the fiber optic cables or patch cords are routed to the FMT, installed within the sliding tray, and secured.
All cables enter the FMT through one of the two sliding entry points, located on the left and right sides of the FMT. When properly installed, the slack loop that forms when the FMT is closed is taken up within the FMT by movement of the sliding radius limiter.
Page 9

ADCP-90-326 • Rev B • November 2020
and Figure 8 show typical cable routing. Prior to routing cables, review the installation
procedure corresponding to the configuration (provided in Subsection 6.3
Then use the following guidelines for routing and installing the cables or patch cords:
1. Open the tray fully, the lock open latch will lock the tray in the open position (see
).
2. Route the cables to the FMT. The cables may be routed from either overhead or under the floor and to the left or right side of the FMT depending on configuration requirements.
3. Secure the cable on the rack using a cable clamp such as shown in Figure 7 and
.
Note: Install the cable clamp kit following the instructions provided in the installation drawing shipped with the kit. Ribbon blocking kits are available from CommScope in a variety of sizes to match any ribbon cable type.
4. Route the cables into the FMT through the specified sliding radius limiter(s).
5. Route and connect the cables within the FMT as required by the configuration. Refer to the installation procedure that corresponds to the FMT configuration.
6. Adjust the cables within the FMT until all excess slack is removed or stored.
7. Secure the cables to the back of the FMT at the rear tie-off point (see Figure 7
Note that a tie-off point is provided on both the left and right side.
8. Use the kurly locks provided to bundle fibers together between the sliding radius limiter and the rear radius limiter as needed.
9. Adjust the cable position with the cable clamp as required to remove excess slack.
10. Release the lock open latch and close the tray (see Subsection 7.4
).

7 OPERATION
The term “operation” refers to procedures performed on an ongoing basis after the FMT is installed. The only FMT trays that require operation are those having a termination function.
Patch cords may be installed in such trays for use in connecting or testing equipment. When routing patch cords, refer to the routing diagrams provided in
Section 6 Installing and Routing
Cables . For instructions on accessing adapters, refer to the following instructions.
7.1
Opening Tray
Caution: Placing a load in excess of 5 pounds (2.3 kg) onto an open tray will result in misalignment or damage to the tray.
To open the FMT tray, slide the release tabs inward with both hands and pull the drawer straight
out as far as it goes. The latch locks the tray in the open position as shown in Figure 20
.

Accessing Sliding Adapter Packs
Danger: Infrared radiation is invisible and can seriously damage the retina of the eye. Do not look into the ends of any optical fiber. Do not look directly into the optical adapters of the adapter packs. Exposure to invisible laser radiation may result. An optical power meter should be used to verify active fibers. A protective cap or hood MUST be immediately placed over any radiating adapter or optical fiber connector to avoid the potential of radiation exposure. This practice also prevents dirt particles from entering the adapter or connector .
Note: Always inspect connectors and adapters when connecting connectors to adapters.
For cleaning procedures, refer to ADCP-90-139.
To access a sliding adapter pack ( Figure 21 ):
1. Route the patch cord into the tray as shown in the appropriate diagram in Section 6
.
2. Lift up the release tab and slide up the adapter pack.

Accessing Bulkhead Plate Adapters
Danger: Infrared radiation is invisible and can seriously damage the retina of the eye. Do not look into the ends of any optical fiber. Do not look directly into the optical adapters of the adapter packs. Exposure to invisible laser radiation may result. An optical power meter should be used to verify active fibers. A protective cap or hood MUST be immediately placed over any radiating adapter or optical fiber connector to avoid the potential of radiation exposure. This practice also prevents dirt particles from entering the adapter or connector .
Note: Always inspect connectors and adapters when connecting connectors to adapters.
For cleaning procedures, refer to ADCP-90-139.
Use the following procedure to connect a patch cord to an FMT having bulkhead plate adapters:
1. Route the patch cord into the tray as shown in the appropriate diagram in Section 6
.
2. Pull the dust cap straight out.
3. Connect the patch cord connector to the adapter.
4. Close the tray.
7.4
Closing the Tray
Close the tray using the following procedure:
1. If closing a tray with sliding adapter pack, fully lower and seat all adapter packs.
2. Assure that all cables and fibers are properly secured and located below the top surface of the tray.
3. Assure that all unused adapters are covered with dust caps.
4. Release the lock open latch (“unlocked position” shown in Figure 20 on page 23 ).
5. Slowly close tray, observing that no fiber kinks or microbends occur as a result of fiber routing.
