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.
