Hi there...

I have an SP578A 8 port swith, that has all LED's ON without any network cables connected. It's old so I have no desire to send it to MICRONET for repair. Can anyone help me?

Is it a problem with the power supply?

How can I recover it. I'm not interest in buying a new one.
 

Hi,
Maybe there is a problem in filtering capacitor of power supply unit.
Please check the capacitor of following to the rectifier circuit.
