1. INTRODUCTION

This instruction sheet provides proper handling and

installation and removal guidelines for

AMP NETCONNECT MRJ21 cable assemblies.

To obtain information on AMP NETCONNECT products,

call PRODUCT INFORMATION at the number at the

bottom of this page or visit the AMP NETCONNECT

website at www.ampnetconnect.com

2. PROPER HANDLING

It is important to exercise the following proper handling

procedures when transporting and installing cable.

— ALWAYS pull cable off of a reel from the

connector end marked "UNWIND FROM THIS END".

DO NOT pull the cable from the wrong end; otherwise,

the cable will tangle.

— Take care to not drop or crush the connectors.

DO NOT hit the connector ends against any hard

surface. Dropping or hitting the connector against a

hard surface may result in bending or breaking of the

front mating shield.

— Observe and implement proper minimum cable

bend radius and pulling tension per TIA-568.

— DO NOT attempt to connect a connector with a

damaged front mating shield. DO NOT attempt to

repair a damaged front mating shield.

3. INSTALLATION AND REMOVAL GUIDELINES

3.1. Installation

1. Align the polarizing key of the plug with the

polarizing key (marked on the back of the patch

panel or cassette assembly) of the receptacle. Refer

to Figure 1.

A label marked “KEY”, attached to the plug,

indicates the location and orientation of the

polarizing key.

Failure to observe location of the polarizing keys

may result in improper wiring connection and initial

electrical and communications start-up testing.

DO NOT attempt to overcome the polarizing keys

by force.

2. Insert the plug into the receptacle until it bottoms.

Ensure that the plug is fully seated into the

receptacle before tightening the jack screws.

Failure to bottom the plug may result in stripping or

cross threading of the jack screws.

3. Using a long, thin, small cross-recessed tipped

screwdriver, turn each jack screw CLOCKWISE.

Tighten each screw to a maximum torque of 0.23 N-m

[2 lbf-in]. DO NOT use an automatic screwdriver.

To avoid cross-threading or stripping of the jack

screws or damage to the receptacle, DO NOT

over-tighten the jack screws.

3.2. Removal

Using a small cross-recessed tipped screwdriver, turn

each jack screw of the plug COUNTERCLOCKWISE

until it is loose, then gently but firmly pull the plug

away from the receptacle until it is released.

To avoid damage to the receptacle, ensure that the

jack screws are fully loosened before pulling the

plug, and DO NOT attempt to remove the plug

by force.

4. REPLACEMENT AND REPAIR

MRJ21 cable assemblies are not repairable. DO NOT

use any defective or damaged components.
