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

2 Connect the other end of the network cable to an
active network port.
