Connecting to the Network

This section describes how to connect 10 Mbps or 100 Mbps network cables to the Fast EtherLink EISA adapter.

You must connect the adapter to the network before loading drivers.

The backplate of the Fast EtherLink EISA adapter contains one RJ-45 connector. The adapter automatically senses and switches speed based on the type of hub to which it is connected.

For 10BASE-T Ethernet networks, the Fast EtherLink EISA adapter uses Category 3, 4, or 5 unshielded twisted-pair (UTP) cable. For 100BASE-TX Ethernet networks the Fast EtherLink EISA adapter supports Category 5 UTP cabling. Refer to Appendix A for more information on cabling.

Figure 2-3 shows the backplate of the Fast EtherLink EISA adapter with its RJ-45 connector.

Three LEDs are located to the left of the RJ-45 connector. From left to right the LEDs are 100 Mbps, 10 Mbps, and ACT. Refer to Table 5-2 for a summary of LED functions.
