3.6.7 Network Interface Controller (NIC)
3.6.7.1 Intel 82541
The Intel 82541 gigabit network interface controller supplies the server board with a single
network interface. The 82541 controller is capable of supporting 10/100/1000 operation and
alert-on-LAN functionality. The controller can be disabled by using the BIOS Setup Utility
accessed during POST. The 82541 supports the following features:
• 32-bit PCI Rev. 2.3 compliant master interface
• Integrated IEEE 802.3 10Base-T, 100Base-TX and 1000Base-TX compatible PHY
• IEEE 820.3ab auto-negotiation support
• Full duplex support at 10 Mbps, 100Mbps and 1000 Mbps operation
• Integrated UNDI ROM support
• MDI/MDI-X and HWI support
3.6.7.2 NIC Connector and Status LEDs
The Intel 82541 network controller drives two LEDs located on the network interface connector.
The link/activity LED (to the left of the connector) indicates network connection when on, and
Transmit/Receive activity when blinking. The speed LED (to the right of the connector) indicates
1000-Mbps operations when amber, 100-Mbps operations when green, and 10-Mbps when off.
3.6.8 USB 2.0 Support
The USB controller functionality integrated into Intel 6300ESB I/O Controller provides the server
board with the interface for up to four USB 2.0 ports. Two external connectors are located on
the back edge of the server board. One internal 2x5 header is provided which is capable of
supporting an additional 2 optional connectors.
