Gigabit Ethernet port The server comes with an integrated Gigabit Ethernet controller. This controller provides an interface for connecting to 10-Mbps, 100-Mbps, or 1000-Mbps networks and provides full-duplex (FDX) capability, which enables simultaneous transmission and reception of data on the Ethernet local area network (LAN). To access the Ethernet port, connect a Category 3, 4, or 5 unshielded twisted-pair (UTP) cable to the RJ-45 connector on the rear of the server. Note: The 100BASE-TX/1000BASE-T Fast Ethernet standard requires that the cabling in the network be Category 5 or higher. The Ethernet (RJ-45) connector has two lights. The upper Ethernet status LED is on the right and displays the link and activity status for the upper Gigabit Ethernet port. When the LED is green the link is active. When the LED blinks green and amber there is activity on the Ethernet LAN. The lower Ethernet status LED is on the left and displays the link and activity status for the lower Gigabit Ethernet port. When the LED is green the link is active. When the LED blinks green and amber there is activity on the Ethernet LAN (see "Server controls and indicators" on page 4). Configuring the Gigabit Ethernet controller The server comes with an integrated Ethernet controller. This controller provides an interface for connecting to 10-Mbps, 100-Mbps, or 1000-Mbps networks and provides full duplex (FDX) capability, which enables simultaneous transmission and reception of data on the Ethernet local area network (LAN). When you connect the server to the network, the Ethernet controller automatically detects the data-transfer rate (10-Mbps, 100-Mbps, or 1000-Mbps) on the network and then sets the controller to operate at the appropriate rate. In addition, if the Ethernet ports that the server is connected to support auto-negotiation, the Gigabit Ethernet controller will set the appropriate duplex state. That is, the Ethernet controller will adjust to the network data rate, whether the data rate is standard Ethernet (10BASE-T), Fast Ethernet (100BASE-TX/1000BASE-T), half duplex (HDX), or full duplex (FDX). The controller supports half-duplex (HDX) and full-duplex (FDX) modes at both speeds. Note: See the documentation on the Broadcom NetXtreme Gigabit Ethernet Software CD that came with the server for information about configuring the Ethernet controller. 150 xSeries 445 Type 8870: Hardware Maintenance Manual and Troubleshooting Guide
