Hi,
I have a print server AXIS OfficeBasic AXIS3EE71E (product no 0107-1), which should be powered by AC adapter PS-B 12V, 500mA (data taken from the manual). Unfortunately, I do not have such power supply unit, but I have another with parameters 12V, 1000mA. The problem is that I do not know what the voltage polarity is expected this print server on your round power socket. Is the "+" is to be in the middle, and "-" on the circumference, or vice versa?
Maybe someone has the original power supply PS-B (12V 500mA), and could tell me what is the polarization voltage at the plug from the power supply?
Alternatively - how to verify experimentally, of course, without damaging the print server, what should be the polarization voltage on the slot.

you should see the polarization on a sticker on the original PSU, yes. if you dont have that then you can use a multimeter to check. just check that both PSU's display the same voltage when a multimeter is connected. if one is negative voltage and one is positive when holding the meter the same way on both PSU's then you know they are not compatable.
