Assignment 2



A punch down tool, also called a punchdown tool or a Krone tool (after wiring systems manufacturer ADC krone), is a small screw-driver sized tool used for connecting wiring to a punch down block[1]. The tool consists of a handle with a spring mechanism inside and at the tip a small square piece of metal with a square hole in it. To use the punch down tool, a wire is inserted in between the two metal blades on a punch down block and the punch down tool is pressed down on top of the wire and the two blades on the punch down block. This requires a bit of pressure until with an audible snap the wire is stripped and contact made as it is pushed down between the two punch down block blades.
66 and 110 blocks require different types of blades.

A 110 block is a type of punch block used to connect sets of wires in a structured cabling system. 110 is also used to describe a type of Insulation-displacement connection used to terminate twisted-pair cables which uses the same punchdown tool as the 110 block.

PATCH PANEL -A patch panel is a mounted hardware unit containing an assembly of port locations in a communications or other electronic or electrical system. In a network, a patch panel serves as a sort of static switchboard, using cables to interconnect computers within the area of a local area network (LAN) and to the outside for connection to the Internet or other wide area network (WAN). A patch panel uses a sort of jumper cable called a patch cord to create each interconnection.
