Intel® Server Board SE7505VB2 PCI I/O Subsystem 5.4 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 mm2 package. The 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 15mm2 TFBGA. The baseboard supports independent 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 5.4.1 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. Revision 1.2 39 Intel part number C32194-002

Intel® Server Board SE7505VB2
PCI I/O Subsystem
5.4
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
2
package. The
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.
±
