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 of 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 Connection
The 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.
