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 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
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

Your computer's NIC connector (an RJ45 connector located on the back panel) is
designed for attaching an unshielded twisted pair (UTP) Ethernet cable. Press one end
of the UTP cable into the NIC connector until the cable snaps securely into place.
Connect the other end of the cable to an RJ45 jack wall plate or to an RJ45 port on a
UTP concentrator or hub, depending on your network configuration. Observe the fol-
lowing cabling restrictions for 10BASE-T and 100BASE-TX networks.
