Making Network Connections
One wire pair should be connected to pins 1 and 2 of the connector, and
another wire pair should be connected to pins 3 and 6. Detailed pinout
information for 10BASE-T/100BASE-TX connectors can be found in
Appendix B.
Plug the RJ-45 connector at one end into the network station, and at the other
end into a free 10BASE-T port (ports 5 through 12) at the front o f the switch.
When both the switch and the device at the other end of the connection are
turned on, and the cable is connected at both ends, then the Link/Act LED
should light. If it does not, then:
♦ Be sure that the connectors are seated correctly at both ends of the
cable.
♦ Check the continuity of the wires in the cable, as well as the pin
assignments on the RJ-45 connectors.
♦ Be sure that the network station to which the port is connected is
plugged in and powered on.
♦ Be sure that you are using a Category 3 or better straight-through (not
crossover) cable.
If you are connecting the switch to an Ethernet hub (or another Ethernet
switch with an MDI-X port), you will need to use a crossover cable. A
crossover cable can be made easily; pinout information for 10BASE-
T/100BASE-TX crossover cables can be found in Appendix FIXME.
100BASE-T ConnectionThe procedure for connecting 100BASE-TX Ethernet stations to the switch is
the similar to that for 10BASE-T. Cabling for 100BASE-TX should be
certified as Category 5 or better, and should be installed by a professional
cable installer.
