$XGLR&RQWUROOHU
Your system has a Crystal CS4236B audio controller. If your system came with a Dell-
installed operating system, the audio drivers for that operating system are installed on
your hard-disk drive. For information on reinstalling audio drivers, reconfiguring the
audio controller, or using the audio utilities provided with your system, see “Using the
Audio Controller” in your online
System Users Guide

Your system may have an integrated 10/100-megabit-per-second (Mbps) 3Com PCI
3C905B-TX Ethernet NIC. The NIC provides all the functions of a separate network
expansion card and supports both the 10BASE-T and 100BASE-TX Ethernet standards.
The NIC includes a Wakeup On LAN feature that enables the computer to be started
up by a special LAN signal from a server management console. Wakeup On LAN pro-
vides remote computer setup, software downloading and installation, file updates,
and asset tracking after hours and on weekends when local area network (LAN) traffic
is typically at a minimum.
The NIC connector on the computer’s back panel has the following indicators (see Fig-
ure 4-1):
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
