1Introduction
Product Overview
The LAN24225 and LAN34225 are server grade, dual Gigabit Ethernet Modules. They provide two Small Form-factor Pluggable (SFP)
connectors that will accept a pre-installed multi-mode Fiber SFP module, or a customer supplied SFP module. This allows the flexibility to have
any combination of multi-mode fiber, single-mode fiber, or twisted pair interfaces. A PCIe x4 interface ensures excellent bandwidth for
communication with the CPU.
Board Features
The following sections describe the major features of the LAN24225 server grade dual Gigabit Ethernet communication module.
General Features
oPCIe x4 Connection
PCIe/104 or PC/104-Express Type 2 connection
oTwo Independent Gigabit Ethernet Connections
1000 Mbps SFP on each channel
Does not support 10/100 Mbps
Full Duplex support
Supports Wake on LAN
oChipset
Intel 82575EB PCIe Gigabit Ethernet Controller
Pre-boot eXecution Environment (PXE) enables system to boot up via the LAN
oGigabit MAC/PHY Advanced Features
Intel® I/O Acceleration Technology (Intel® I/OAT) accelerates TCP I/O for improved CPU utilization.
MSI-X support minimizes the overhead of interrupts and allows load balancing of interrupt handling between
cores/CPUs.
Mechanism available for reducing interrupts generated from Tx/Rx operations to maximize system
performance and throughput.
Dual 8 kB configurable Rx and Tx FIFO buffers means no external FIFO memory requirements.
Support for transmission and reception of jumbo frames up to 9.5kBytes enables higher and better throughput
of data.
IEEE 802.3 compliant flow-control support with software-controllable pause times and threshold values to
reduce frame loss from receive overruns.
oHost Offloading Features
Direct Cache Access (DCA) enables the I/O device to activate a pre-fetch engine in the CPU that loads the
data into the CPU cache before use, eliminating cache misses and reducing CPU load.
Checksum offloading, segmentation offloading, and packet filtering capabilities lower processor utilization.
IEEE 802.1q virtual local area network (VLAN) support with VLAN tag insertion, stripping and packet filtering
for up to 4096 VLAN tags allows creation of multiple VLAN segments.
oMulti-Mode SFP (with -1 option)
Avago AFBR-5715APZ or equivalent
850nm
For use with Multi-Mode Fiber Optics
LC Connector
Bail latch
Software
oSupports Windows 7/XP (included on companion CD)
oOpen source Linux drivers included in the kernel
oDrivers included in most modern operating systems. Check with the OS manufacturer

Board Handling Precautions
To prevent damage due to Electrostatic Discharge (ESD), keep your board in its antistatic bag until you are ready to install it into your system.
When removing it from the bag, hold the board at the edges, and do not touch the components or connectors. Handle the board in an antistatic
environment, and use a grounded workbench for testing and handling of your hardware.
