Hi,

Do you have a second PSU in each switch? If you do, is the power connected to each PSU? As you can see below, it says "no input power"

1B Unknown Unknown No Input Power Bad Bad Unknown

Hi, no i don´t have a second PSU.

OK, so that basically says, you don't have a second PSU installed in each switch.

Yes, but thats the problem, i have a monitoring system and it reports that the switch its down because of this. The switch doesn´t show that doesn´t have a PSU, it has an unknown condition on the B slot.
