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.

The Intel® X710 Ethernet Controller uses open firmware designed to optimize compatibility with compliant SFP+ modules. RTD has validated board
operation with the following modules:
•Intel e10gsfpsr (0-70°C, SR module)
•Intel e10gsfplr (0-70°C, LR module)
•Netgear AXM761 (0-70°C, SR module)
5.3 Driver Support
The Ethernet controller is supported by a driver provided by Intel, but only in Windows Server Editions. Check Intel’s
website (www.intel.com) for additional information and updates.
Under Linux, the Ethernet controller is supported via the i40e kernel module that is included with recent Linux 2.6.32
kernels. Most modern desktop Linux distributions will automatically detect the Ethernet controller and load the
necessary drivers. Contact the vendor of your Linux distribution for more information.
For other operating systems, the Ethernet controller may be natively supported via built-in drivers. Your operating
system vendor should be able to provide the necessary information.
