I am trying to modify a Netgear GS108 8-Port gigabit switch with POE on 4 of the ports. Problem is that when I go to test to find out what pins 4/5 and 7/8 are in order to place the positive and negative terminals too, it shows continuity on every pin of each of the 8!
So in other words, no matter what pin I test for, it always shows continuity so I never know what pin is not being used!
Here is a picture of the board:
Any help would be greatly appreciated since I do not want to fry it :o)
If I were to connect pins 4/5 (positive) and 7/8 (negative) to the first 6 ports (ports 1-6) I understand that they would be forced to use 10/100mbps instead of 10/100/1000mbps. That being said, would the other 2 ports (7 & 8) be forced to use 10/100mbps as well or would they operate at the normal 10/100/1000mbps?
