Intel® Server Boards S5520HC, S5500HCV, and S5520HCT TPS Functional Architecture 3.12 Network Interface Controller (NIC) The Intel® Server Boards S5520HC, S5500HCV and S5520HCT provide dual onboard LAN ports with support for 10/100/1000 Mbps operation. The two LAN ports are based on the onboard Intel® 82575EB controller, which is a single, compact component with two, fullyintegrated GbE Media Access Control (MAC) and Physical Layer (PHY) ports. The Intel® 82575EB controller provides a standard IEEE 802.3 Ethernet interface for 1000BASE-T, 100BASE-TX, and 10BASE-T applications (802.3, 802.3u, and 802.3ab) and is capable of transmitting and receiving data at rates of 1000 Mbps, 100 Mbps, or 10 Mbps. Each network interface controller (NIC) port provides two LEDs: ƒ Link/activity LED (at the left of the connector): Indicates network connection when on, and transmit/receive activity when blinking. ƒ The speed LED (at the right of the connector) indicates 1000-Mbps operation when amber; 100-Mbps operation when green; and 10-Mbps when off. The following table provides an overview of the LEDs. Table 15.
