Your system has an integrated 10/100–megabit-per-second (Mbps) network interface
controller (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
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.
Your computer's RJ45 NIC connector is designed for attaching an unshielded twisted
pair (UTP) Ethernet cable equipped with standard RJ45-compatible plugs. Press one
end of the UTP cable into the NIC connector until the plug 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.
For 10BASE-T networks, use Category 3 or greater wiring and connectors.
For 100BASE-TX networks, use Category 5 or greater wiring and connectors.
The maximum cable run length (from a workstation to a concentrator) is 328 feet
(ft) (100 meters [m]).
For 10BASE-T networks, the maximum number of daisy-chained concentrators
on one network segment is four.

Your system contains two Universal Serial Bus (USB) connectors for attaching USB-
compliant devices. USB devices are typically peripherals such as keyboards, mice,
printers, and computer speakers.

If you reconfigure your hardware, you may need pin number and signal information for
the USB connectors. Figure B-7 illustrates the pin numbers for the USB connectors,
and Table B-6 lists and defines the pin assignments and interface signals for the USB
connectors.
