Step2. If the device is a network card and the switch is in the wiring closet, attach the
other end of the cable segment to a modular wall outlet that is connected to
the wiring closet. (See the section “Network Wiring Connections.”) Otherwise,
attach the other end to an available port on the switch.
Make sure each twisted pair cable does not exceed 100 meters (328 ft) in length.

unless it is actually required to solve a problem. Otherwise
back pressure jamming signals may degrade overall

Today, the punch-down block is an integral part of many of the newer equipment racks.
It is actually part of the patch panel. Instructions for making connections in the wiring
closet with this type of equipment follows.
Step1. Attach one end of a patch cable to an available port on the switch, and the
other end to the patch panel.
Step2. If not already in place, attach one end of a cable segment to the back of the
patch panel where the punch-down block is located, and the other end to a
modular wall outlet.
Step3. Label the cables to simplify future troubleshooting. See “Cable Labeling and
Connection Records” on page 29
