In this lab, the student will learn to wire an RJ-45 data jack for installation in a wall plate using a punch-down tool. These skills are useful when it is necessary to install a small amount of cabling in an office or residence. A punch tool is a device that uses spring-loaded action to push wires between metal pins, while at the same time skinning the sheath away from the wire. This ensures that the wire makes a good electrical connection with the pins inside the jack. The punch tool also cuts off any extra wire | Cisco SrsTEMS Lab RJ-45 Jack Punch Down Objective Learn the correct process for terminating or punching down an RJ-45 jack Learn the correct procedure for installing the jack in a wall plate Background Preparation In this lab the student will learn to wire an RJ-45 data jack for installation in a wall plate using a punch-down tool.

CAT 5 or CAT 5e cabling and CAT 5 or 5e rated T568-B jacks will be used. A CAT 5 5e straight-wired patch cable with an RJ-45 connector will normally plug into this data jack or outlet to connect a PC in a work area to the network. It is important to use CAT 5 or 5e rated jacks and patch panels with CAT 5 or 5e cabling in order to support Fast Ethernet 100 Mbps and Gigabit Ethernet 1000 Mbps . The process of punching down wires into a data jack in an office area is the same as punching them down in a patch panel in a wiring closet. The following resources are required 60 - 90 cm 2 - 3 feet length of CAT 5 5e cabling which can be one per person or one per team Two CAT 5 5e RJ-45 data jacks one extra for spare - If RJ-45 data jacks are installed on both ends of the cable the installation can be tested by inserting cable with RJ-45 connectors and a simple cable continuity tester. CAT 5 5e wall plate 110 type punch-down tool Wire cutters Use the following procedure and diagram to punch down the wires into the RJ-45 jack and install the jack into the wall plate Step 1 Remove the jacket cm 1 inch from the end of the cable. Step 2 Position wires in the proper channels on the jack maintaining the twists as closely as possible. The diagram below
