Integrated Network Interface Controller Connector
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 system to be started by a special local area network (LAN) signal from a server management console.
Wakeup On LAN provides remote system setup, software downloading and installation, file updates, and asset tracking after hours and on weekends when LAN
traffic is typically at a minimum.
Network Cable Requirements
Your system'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 following cabling restrictions for 10BASE-T and 100BASE-TX networks.
l For 10BASE-T networks, use Category 3 or greater wiring and connectors.
l For 100BASE-TX networks, use Category 5 or greater wiring and connectors.
l The maximum cable run length (from a workstation to a concentrator) is 328 feet (ft) (100 meters [m]).
l For 10BASE-T networks, the maximum number of daisy-chained concentrators on one network segment is four.
