Before starting, plug the DLink wall-wart into an outlet and test your connector with a multi-meter.
Your meter must read 5v
positive when the red probe is inside the barrel connector and the black probe is touching the outside.
These
BEFORE readings will give you experience with what the readings should be after you've done your rewiring.
Roughly, there is a special 12v regulated power port on the Power Distribution Panel expressly for the use of the DLink.
Power Distribution Panel -> 12v/5v converter -> DLink barrel connector
After wiring, test your connector with a multi-meter again before plugging it into the DLink.
Your meter must read 5v
positive when the red probe is inside the barrel connector and the black probe is touching the outside.
After you're sure you've got it right and you've tested it.
Get someone else to test it separately before event thinking of plugging it into the DLINK itself.
