Dual Port 10g Bypass RJ45

Two 10 Gigabit Ethernet Copper Ports, RJ45, with Hardware Failover/Bypass

The Silicom PE210G2BPI40 is built on Intel\'s x540 Gigabit technology designed to spread interrupts across multicore CPU systems. The hardware Failover/Bypass function allows systems incorporating the PE210G2BPI40 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 PE210G2BPI40 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
