Intel Desktop Board D915GUX/D915GHA Technical Product Specification Table 5 describes the LED states when the board is powered up and the 10/100 Mbits/sec LAN subsystem is operating. Table 5. LAN Connector LED States LED Color LED State Condition Green Off LAN link is not established. On LAN link is established. Blinking LAN activity is occurring. Yellow Off 10 Mbits/sec data rate is selected. On 100 Mbits/sec data rate is selected. 1.10.2 Gigabit LAN Subsystem The Gigabit (10/100/1000 Mbits/sec) LAN subsystem includes the Marvell Yukon 88E50 and an RJ-45 LAN connector with integrated status LEDs. 1.10.2.1 Marvell Yukon 88E8050 PCI Express 1.0a Integrated MAC/PHY Gigabit Ethernet Controller The Marvell Yukon 88E8050 provides the following functions: • x1 PCI Express link • Basic 10/100/1000 Ethernet LAN connectivity • IEEE 802.1p and 802.1q support • 10/100/1000 IEEE 802.3 compliant • Compliant to 802.3x flow control support • Jumbo frame support • TCP, IP, UDP checksum offload • Automatic MDI/MDIX crossover • Full device driver compatibility • Configuration EEPROMs that contain the MAC address and ASF 2.0 support • Wake On LAN technology power management support • PCI Express Active State Power Management Support (L0s) • ASF 2.0 support 1.10.2.2 RJ-45 LAN Connector with Integrated LEDs Two LEDs are built into the RJ-45 LAN connector (as shown in Figure 12). Table 6 describes the LED states when the board is powered up and the Gigabit LAN subsystem is operating. Green LED Green/Yellow LED OM16513 Figure 12. LAN Connector LED Locations 32
