Notes: 1. When connected to a shared collision domain (such as a hub
with multiple workstations), switch ports must be set to
half-duplex mode.
2. 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.
3. As each connection is made, the green Link LED (on the EdgeIron
4802CF) corresponding to each port will light to indicate that the
connection is valid.
Wiring Closet Connections
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
follow.
1. Attach one end of a patch cable to an available port on the switch, and
the other end to the patch panel.
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.
3. Label the cables to simplify future troubleshooting.
