Dual RJ45 Ethernet Connector Breakout Board w/LED 180 Vertical Din Rail Mount

I'm going to be using this to supply a variable voltage to (2) pairs going to a PoE device being evaluated by UL for UL294 testing. This will allow a bench-top power supply to be used (varying voltage from PoE min to PoE max) in place of a PoE injector, and will still allow the data pairs through. Prior to this I'd hacked up a standard CAT6 patch cable to redirect (2) pairs to the power supply. With this set up they will be able to use standard patch cables, and I won't have to worry about the custom cabling being broken.I am not using the LED status light because they would require an external circuit to power them.Note: there are no instructions in the box, not that it needs any, as everything is silk screened.
