The NIC subsystemconnects to the Ethernet network through a single RJ45 connector on theback of the computer. The RJ45 connector and the NIC interface circuitry aremounted on the system board.The NIC connector on the computer’s back panel has the following indicators:á A yellowactivity indicator flashes when the system is transmitting orreceiving network data. (A high volume of network traffic may make thisindicator appear to be in a steady “on” state.)á A greenlink integrity indicator lights up when there is a good connectionbetween the network and the NIC. When the green indicator is off, the sys-tem is not detecting a physical connection to the network.1HWZRUN&DEOH5HTXLUHPHQWVThe computer’s NIC connector (RJ45) is designed for attaching to a UTP Ether-net cable. The other end of the cable connects to an RJ45 jack wall plate or toan RJ45 port on a UTP concentrator or hub, depending on the networkconfiguration.Chapter 4, “Using Integrated Devices,” in theReference and Installation Guideprovides instructions for connecting the computer to, and configuring it for useon, an Ethernet network.
