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.

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.
NOTE i
A label marked “KEY”, attached to the plug, indicates the location and orientation of the polarizing key.

DO NOT attempt to overcome the polarizing keys by force.
2. Insert the plug into the receptacle until it bottoms.
CAUTION

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.
CAUTION
!
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.
CAUTION
!
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.
