Dual 82575 bypass

Dual Port Gigabit Failover RJ45

For use with 8+ Core Cpus

The ET/GigFailover is built on Intel's 82575 Gigabit technology designed to spread interrupts across multicore CPU 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
