Step 2:
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 (eee 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.
Step 3:
As each connection is made, the Link LED (on the switch) corresponding to
each port will light green (1,000 Mbps) or amber (100 Mbps) to indicate that the
connection is valid.

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 are as follows:
Step 1:
Attach one end of a patch cable to an available port on the switch, and the
other end to the patch panel.
Step 2:
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.
Step 3:
Label the cables to simplify future troubleshooting.

NOTE:
Avoid using flow control on a port connected to a hub
unless it is actually required to solve a problem. Otherwise
back pressure jamming signals may degrade overall
performance for the segment attached to the hub.
