2.4.8.1
GigE Controller 82574L
The 82574 family (82574L and 82574IT) are single, compact, low-power components that
offer a fully-integrated Gigabit Ethernet Media Access Control (MAC) and Physical Layer
(PHY) port. The 82574 uses the PCI Express* architecture and provides a single-port
implementation in a relatively small area so it can be used for server and client
configurations as a LAN on Motherboard (LOM) design.
External interfaces provided on the 82574:

External interfaces provided on the 82574:
PCIe Rev. 2.0 (2.5 GHz) x1
MDI (Copper) standard IEEE 802.3 Ethernet interface for 1000BASE-T,
100BASETX, and 10BASE-T applications (802.3, 802.3u, and 802.3ab)
NC-SI or SMBus connection to a Manageability Controller (MC)
EEE 1149.1 JTAG (note that BSDL testing is NOT supported)
2.4.8.2
Dedicated 10/100Mbps management port
The KSZ8041NL network PHY is connected to iBMC through RMMII interface as dedicated
management port. This port can only work with Intel
management port. This port can only work with Intel

MAC Address Definition
Each computing node in Intel
®
Server System SR1640HT has the following four MAC
addresses assigned to it at the Intel factory:
NIC 1 MAC address
NIC 2 MAC address – Assigned the NIC 1 MAC address +1
Integrated BMC LAN Channel MAC address – Assigned the NIC 1 MAC address +2
Intel

RMM3 Lite-V) MAC address – Assigned
the NIC 1 MAC address +3

Virtualization Technology for Directed I/O (Intel
®
VT-d)
The Intel
®
3420 PCH provides hardware support for implementation of Intel
®
Virtualization
Technology with Directed I/O (Intel
®
VT-d). Intel VT-d Technology consists of technology
components that support the virtualization of platforms based on Intel
®
Architecture
Processor. Intel VT-d Technology enables multiple operating systems and applications to
run in dependent partitions. A partition behaves like a virtual machine (VM) and provides
isolation and protection across partitions. Each partition is allocated its own subset of host
physical memory.

The Intel
®
Virtualization Technology is designed to support multiple software environments
sharing the same hardware resources. The Intel
®
Virtualization Technology can be enabled
or disabled in the BIOS setup. The default behavior is disabled.
Note: If the setup options are changed to enable or disable the Virtualization Technology
setting in the processor, the user must perform an AC power cycle for the changes
to take effect.
