1Introduction
1.1 Product Overview
The LAN24710 and LAN34710 are dual 10Gb/s Fiber Ethernet Modules. They provide two independent 10Gb/s fiber
Ethernet connections using a single integrated controller chip. Fiber connectivity is provided by standard SFP+
modules (specific modules listed below have been validated by RTD to work with the LAN24710 and LAN34710).
These boards run completely off of the PCI Express bus, utilizing Intel’s X710 10 Gigabit Ethernet controller.
The LAN24710 is the PCI/104 Express version that has a pass-through PCI connector.
1.2 Board Features
•PC/104 form factor
•PCIe x4 Gen3 Interface
•PCIe/104 stackable bus structure
oPCIe Type 2 expansion bus
oPCI pass-through expansion bus (LAN24- versions only)
•2 Independent 10Gb/s Fiber Ethernet Connections
oIntel X710 controller chip
oSFP+ module sockets to support the following standards:
▪10GBASE-SR
▪10GBASE-LR
▪SFP+ Direct Attach Cable
oBackward compatibility with 1Gb/s standard
•10/1 GbE data rate per port: support for vision systems, network and server virtualization, and LAN and SAN flexibility
•Connector for LEDs to monitor Link Status and Activity for each port
1.3 Ordering Information

3.1 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.
