Figure 2-2 Connecting Twisted-Pair Cable

The Fast EtherLink 10/100BASE-T4 PCI adapter is equipped with an on-board transceiver for connection to twisted-pair cable. To establish a valid 10 Mbps connection, the cable must be connected to a 10BASE-T hub. To establish a valid 100 Mbps connection, the cable must be connected to a 100BASE-T4 hub.

Connect the network cable as follows:

1Make sure that the connector on your cable is wired appropriately for standard 10BASE-T or 100BASE-T4 adapters.
