Figure 7

 and 

Figure 8

 show typical cable routing. Prior to routing cables, review the installation

procedure corresponding to the configuration (provided in 

Subsection 6.3

 through 

Section 6.6

).

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

Subsection 7.1

).

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

 an

Figure 8

.

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

 and 

Figure 8

).

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

).

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.
