110 Punchdown Wiring Guide

 

Terminating 110-style Patch Panels and Wallplates

The following instructions should help you to connect your wallplate and/or patch panel with the 110-type punch down connector to your Cat5 cabling.

1) Step One: Strip the outer jacket off of the cable, exposing the colored conductors. You should strip off no more than two inches. Take care to make sure the colored conductors are not damaged. A tool such as the Cyclops wire stripper (CTG ref# 09732) is perfect for this task.

2) Step Two: Carefully separate the colored conductors. To insure Category 5 transmission performance, you should not untwist the paired conductors more than ½ an inch.

3) Step Three: Carefully place each conductor into the appropriate slot on the 110 block, one pair at a time, and punch them down using a 110-type punch tool (CTG ref# 15739 or 05955). To insure Category 5 transmission performance, punch the conductors from the center to the outside. Use the following diagrams to aid with the proper placement of the conductors. There are two common types of 110 blocks. Use the diagram that matches your configuration.

4) Step Four: Trim excess so conductors are flush, and place strain relief caps over the connections. Jack should now be ready for use.

Things to Remember
1) Solid conductors should always be used. Stranded conductors do not always make a good connection.
2) Never terminate a cable run with 110-type on one end and RJ-45 (modular plug) on the other end. This more often than not will cause problems and does not conform to EIA Category 5 specifications. If you have a wall plate/patch panel at one end of a cable run, you should also have a wall plate/patch panel at the other end of the cable run. If you have an RJ-45 at one end of a cable, the other end must also have an RJ-45.
3) The above diagrams describe the color code for the EIA/TIA 568B standard. If your wall plates/patch panels conform to EIA/TIA 568A standards, simply reverse the green and orange pairs.
