The integrated 10/100-megabit per second (Mbps) 3Com PCI 3C905b-TX Ethernet
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 local area network (LAN) signal from a server management console.
Wakeup On LAN provides remote computer setup, software downloading and instal-
lation, file updates, and asset tracking after hours and on weekends when LAN traffic
is typically at a minimum.
The NIC connector on the computer’s back panel has the following indicators (see
Figure 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
