I opened up a Cisco network switch that no longer powers on and the power supply has three blown components:
(See Photos Attached)
-Power switch IC
-Optocoupler
-Resistor
There are no blown fuses, mosfets, diodes. I know its impossible to ask what could cause this without physically looking at the board but does anybody know
what could have caused these components to blow?
Also finding a replacement power IC seems to be a bit of a mission as the top blew off and I cannot see the model of the IC. Can anyone help?
