So I got a bunch of telecom boards and there were a few of these in the box:
What I'm wondering is what those boxes are? I pulled one off the board and it was basically a sealed metal box with 9-10 pegs on the bottom soldered to the board. I'm just wondering if there's anything of value in there, or if I were to smash it open myself, if its safe to do so or if I'm risking electrocution or something.
Thanks
