Bypass Ports on Axiomtek NA-820: PowerRouter 732 etc

Is anyone getting use out of the bypass port function on the NA-820 board?

I was reading the manual and saw that theres jumpers with these choices
Disabled (Default)
Enabled
GPIO/Watchdog/Power

We’ve had occasional issues with the compact flash cards, I’ve convinced the people I work with to try an SSD as the boot drive.

Looks as though, even in the Disabled setting, when the board is powered off, Ether 2 and 3 are bypassed, along with 4 and 5
