These skills are useful when you must 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.</p> <p class="smtext">You will work with CAT 5 cabling and CAT 5 rated T568-B jacks. A CAT 5 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 that you use CAT 5 rated jacks and patch panels with CAT 5 cabling in order to support higher speed versions of Ethernet such as Fast Ethernet which is 100Mbps. 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 such as a Main Distribution Facility (MDF) or Intermediate Distribution Facility (IDF).</p> </blockquote><p align="left"> <span class="resourceSectionTitle">Tools / Preparation:</span> </p> <blockquote> <p class="smtext">Prior to starting the lab, the teacher or lab assistant should have a spool of Cat 5 Unshielded Twisted Pair (UTP) cable, several RJ-45 data jacks, a 110 Punch down tool and an Ethernet / RJ-45 continuity tester available. Work individually or in teams. The following resources will be required:</p> <span class="smtext"> <ul type="disc"><li>Two to Three foot length of CAT 5 cabling (one per person or one per team)</li><li>Two CAT 5 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</li><li>CAT 5 Wall Plate</li><li>110 type punch down tool</li><li>Wire cutters</li></ul> </span> </blockquote>⌨️ 快捷键说明
