first of all thanks for taking time helping me with this issue.
TL;DR; Identify the blew up component on the picture and win!
I've by mistake done a very short but effective connection in reverse polarity to my cisco switch. Apparently only one component blew up and I pretend to replace it and see if I can save the switch as it is brand new.
During the "explosion" of the component part of it's name got deleted but I'm pretty sure that someone with more experience (or maybe someone with the same switch and good will) can help me identify the component.
Here's the best picture I can take: https://i.imgur.com/xsBTAjJ.jpg
Here's the whole PCB for some context: https://i.imgur.com/CLVEgWY.jpg
The model is SG110D-08 it's a 8-port gigabit switch.
