Network Interface Controller (NIC)

The server board SE7505VB2 supports one 10Base-T/100Base-TX network interface controller
(NIC) based on the Intel 82550PM controller (NIC 1) and one gigabit network interface controller
based on the Intel 82540EM controller (NIC 2).
The 82550PM is a highly integrated PCI LAN controller in a thin BGA 15 mm
controller's baseline functionality is equivalent to that of the Intel 82559 with the addition of
Alert-on-LAN functionality. The 82550PM supports the following features:
Glueless 32-bit PCI, CardBus master interface (Direct Drive of Bus), compatible with PCI
local Bus Specification, Revision 2.2.
Integrated IEEE 802.3 10Base-T and 100Base-TX compatible PHY
IEEE 820.3u auto-negotiation support
Full duplex support at both 10 Mbps and 100 Mbps operation
Integrated UNDI ROM support
MDI/MDI-X and HWI support
Low power +3.3 V device
The 82540EM is a single, compact component with integrated gigabit Ethernet MAC and PHY
layer functions and is packaged in a 15mm
disabling of the two NIC controllers using the BIOS setup menu. The 82540EM supports the
following features:
Support for the 33/66MHz bus segment
Integrated 10/100/1000 Mb/s full and half duplex operation
SMBUS. ASF 1.0, ACPI, WoL and PXE management functions
Compliant w/ PCI Power Management v1.1 and ACPI v2.0

NIC Connector and Status LEDs

The NICs drive two LEDs located on each network interface connector.
For the NIC 1 connector, the green LED indicates network connection when on, and
Transmit/Receive activity when blinking. The green LED indicates 100-Mbps operation when lit,
and 10-Mbps when off.
For the NIC 2 connector, the amber LED indicates network connection when on, and
Transmit/Receive activity when blinking. The green LED indicates 1000-Mbps operation when
lit, the orange LED indicates 100-Mbps operation when lit and 10-Mbps when off.
