10. Installing Dual Stub Connector in

Remote Frames

10.1

 

Remove the MPC from its shipping

container (keep protective material around the

connector assembly).

10.2

 

Mark the stubs cable with the

identification number and pair count of the

cable to which the stubs are to be placed.

10.3

 

Determine the splice location and whether

the stub entrance is from the top of the bottom

of the distribution frame.

10.4

 

Screw the two mounting screws supplied

with the MPC part way into the mounting holes

at the required position 

on the left side of the 

distributing frame vertical

.

10.5

 

Run the one of the stub cable up/down the

distributing frame as required to the splice

location and then the second stub.

10.6

 

Hang the MPC by its mounting bracket

slots on the two screws in the frame vertical.

NOTE: 

Position the MPC so that the plastic stud 

on the top of the connector immediately below 

engages the slot on the bottom of the connector being 

mounted. 

10.7

 

Tighten screws to secure MPC to the

vertical.

10.8

 

Dress one of the stubs to the distribution 

frame, and then dress the second stub. 

10.9

 

Mark the MPC designation strip with the 

number and pair-count of the cable being 

terminated. 

10.10

 

Test the protector modules. 

NOTE: 

Splice stubs to the main cable, as required 

by the job specification, using standard splicing 

procedures for the type of cable involved. 

11. Installing Stubless Connector

NOTE: 

Before proceeding with installation, divide 

the cable to be terminated into 100-pair binders for 

each connector location. 

NOTE: 

A mounting adapter (P0566899) can be 

used to mount the MPC during installation for 

easier access to work areas. This section will describe 

the procedure when using this bracket. 

11.1

 

Pull the 100-pair binders up the frame

until all slack is removed. Binders must extend

at least 625 mm (2 ft.) above the MPC position.

11.2

 

Tie the binder to the transverse arm below

the MPC position.

11.3

 

Separate the 100-pair binder into four

25-pair groups, and tag each group with its

applicable pair count: 1-25, 26-50, 51-75 or

76-100.

11.4

 

Secure the mounting adapter on the frame

vertical with two screws.
