First off, I'm sorry if this is the wrong subforum - None of the others seemed to fit the description.
I've got this Cisco 2960-CX. It works flawlessly otherwise, but won't provide POE to the ports.
On initial inspection, U4701 (An SI3458) has a physical hole in the die. I replaced with another chip out of a dead 2960, and it immediately popped a new hole.
All I've been able to pull up are datasheets for mosfets, and I'm not quite convinced this is a simple FET.
Popping the die implies an overcurrent downstream, correct?
I have 3 more of these chips until I'm SOL. I've also attached the POE board from a 24-port switch for reference.
