2.4.8 
Network Interface Controller (NIC) 
The server boards S3420TH in Intel
®
 
Server System SR1640TH support three network 
interfaces, two is provided from the onboard Intel
®
 82574L GbE PCI Express* network 
controllers; the third one is the onboard 10/100Mbps KSZ8041NL Network controller, only 
enabled by RMM3 Lite-V module for management. 
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: 
    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
®
 RMM3 Lite-V module installed. 
 
2.4.8.3 
MAC Address Definition  
Each computing node in Intel
®
 Server System SR1640HT has the following four MAC 
addresses assigned to it at the Intel factory: 
ƒ
 
NIC 1 MAC address 
ƒ
 
NIC 2 MAC address – Assigned the NIC 1 MAC address +1 
ƒ
 
Integrated BMC LAN Channel MAC address – Assigned the NIC 1 MAC address +2 
ƒ
 
Intel
®
 Remote Management Module 3 (Intel
®
 RMM3 Lite-V) MAC address – Assigned 
the NIC 1 MAC address +3 
 
2.4.9 
Intel
®
 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.
