3Com 10/100BASE-T4 manual Connecting to the Network

Connecting to the Network 2-5

100BASE-T4 connections use all 4 pairs of wire normally contained in a bundle of Category 3, 4, or 5 UTP cable. The “straight through” connection should be made from the Fast EtherLink PCI adapter through the cable and connectors to the hub. No crossover in the cable is required.

Refer to Appendix A for RJ-45 connector pin assignments.

2Align the RJ-45 connector on the end of the twisted-pair cable with the notch on the adapter’s connector and insert it into the adapter connector.

3For 100 Mbps operation, be sure the connection is to a 100BASE-T4 hub port.

4The next step is to install network drivers, as explained in Chapter 3.
