Using the Network Interface Controller

T
his chapter describes how to connect your computer
system to an Ethernet network using the built-in 3Com
Peripheral Component Interconnect (PCI) 3C905TX net-
work interface controller (NIC). The NIC provides all the
functions normally provided by a separate network
expansion card.
This chapter also provides instructions for configuring
the NIC under the following operating systems:
•
Microsoft Windows NT 4.0
•
Microsoft Windows 95
NOTE: The NIC drivers for systems running a
Dell-installed Windows NT 4.0 or Windows 95 operating
system are automatically detected and installed.

Figure 5-1. I/O Ports and Connectors

Instructions for reinstalling these NIC drivers are
included later in this chapter.
The NIC connector on the computer's back panel has the
following indicators:
•
A yellow activity indicator flashes when the system
is transmitting or receiving network data. (A high
volume of network traffic may make this indicator
appear to be in a steady "on" state.)
•
A green link integrity indicator lights up when there
is a good connection between the network and the
NIC. When the green indicator is off, the computer is
not detecting a physical connection to the network.
