Connecting to the Network

This section describes how to connect the 3C900B NIC to an Ethernet network using an RJ-45, BNC, or AUI port. Each 3C900B NIC provides different network ports, as shown in Figure 1-1. Follow the procedure for the network port on the NIC that you install.

When you first install the NIC and power on the PC, the LED on the NIC backplate lights, but the link is not active. To enable the link, you must load the network drivers. See “Interpreting the Link LED” at the end of this chapter for more information.

RJ-45 Port

Follow these steps to connect the RJ-45 port on the 3C900B-TPO and COMBO NICs to the network:

1Plug the RJ-45 connector on the twisted-pair network cable into the RJ-45 port on the NIC backplate. See Figure 1-3.
