The OptiPlex GX1 systems and OptiPlex NX1 systems are available with or without an integrated Ethernet NIC subsystem. The OptiPlex GX1p systems are available only with an integrated Ethernet NIC subsystem. The integrated 10/100-Mbps 3Com® PCI 3C905B-TX Ethernet NIC subsystem supports the Wakeup On LAN feature and the 10BASE-T and 100BASE-T standards. The NIC subsystem connects to the Ethernet network through a single RJ45 connector on the back of the computer. The RJ45 connector and the NIC interface circuitry are mounted on the system board. The NIC connector on the computer's back panel has the following indicators: 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 system is not detecting a physical connection to the network. The computer's NIC connector (RJ45) is designed for attaching to an unshielded twisted pair (UTP) Ethernet cable. The other end of the cable connects to an RJ45 jack wall plate or to an RJ45 port on a UTP concentrator or hub, depending on the network configuration. Chapter 4, "Using Integrated Devices," in the Reference and Installation Guide provides instructions for connecting the computer to, and configuring it for use on, an Ethernet network. For OptiPlex NX1 systems, refer to the online Network Administrator's Guide. For desktop connectivity, the OptiPlex GX1/GX1p and OptiPlex NX1 systems include the following ports: 25-hole, bidirectional parallel port with EPP/ECP and demand-mode DMA support Two Universal Serial Bus (USB) ports Two 9-pin serial ports Two PS/2 ports (mouse and keyboard) One 15-hole video connector Three audio jacks (microphone, line-in, and line-out) One RJ45 Ethernet NIC connector See Figures 1-3 through 1-6 for I/O port identifiers for the various chassis configurations.
