Dual 82571 bypass

ET/GigFailover v2.0 (PCIe)

Two Gigabit Ethernet Copper Ports, 10/100/1000 BaseT, with Hardware Failover/Bypass

The ET/GigFailover is built on Intel's Gigabit technology, and is optimized to support 1x PCIe bus based systems. The hardware Failover/Bypass function allows systems incorporating the ET/GigFailover to eliminate single point of failure concerns by bypassing the system in the event of a power down or software lockup or failure. Additional features allow a system with the ET/Gigfailover to be temporarily taken offline, allowing for safe upgrades or maintenance even from a remote location. A functional description of the bypass function can be found here
