Hi there...

I have an SP578A switch HUB, that when turned ON without any network cables attched, all LED's are ON

Does any one outthere has any idea what it's the problem? I'm planning to recover it.

Thnks

That means there is a serious hardware\firmware error. Try resetting it if you see a small switch in the back.

Crying or Very sad Welll there's a problem there....this is only a switch-hub...not a router...so there are no reset switches on the back...I have measure the output of the powersupply, and notice that only 2.6V comes out. There are 4 wires coming out of the powersupply. 2 I belive that are ground, and the other 2 positive. Between these 2 and the other 2 which I belive to be ground I have 2.6V. I think it's to little. I notice no damage components in the power supply or main board.
