Cut the Cat5e cable with a cable stripper. Trim the cable about 3/4 to 1 inch into the jacket, making sure that you hasn’t damaged the conductors inside. Romove the cut jacket by simply pulling it off.
Separate the twisted wire pairs from each other; Untangle the scrap piece of jacket downwards on each pair of wires and then fan out all four twisted pairs.
Remove the jack’s protective cap. You will see there are wire configurations printed near the termination slots. If you are given a choice between “A” and “B” configurations, choose whichever you are currently using.
Match up the colored wires with the corresponding color codes on the keystone jack by placing all 8 wires into the center of the jack 8 wires into the center of the jack.
Use a punch down tool to punch the wires down into the blades of the keystone jack. To punch down each wire, press down on the punch down tool until you here a loud click and simultaneous, metallic-sounding “ping”. In this step, it is very important to make sure that the blade of the punch down tool is facing the outside of the Cat 5e Modular Jack otherwise it will cut the wires insides.
Inspect each termination slot along the outer edge of the jack; each wire should be firmly anchored at the bottom of its slot, and the wires’ copper conductors will be visible.
Snap the header cover down over the connector.
If your care about the connection quality of your termination, you can use the network cable tester have a test over the terminated cables.
After you have finished the termination for the Cat5e cable with the RJ45 keystone jack, the last thing left is to assemble the terminated modular jacks with the wall network faceplate and fixed them in the wall.
