external 5vdc supply

[JV]

Hi every one
Just a simple question
I would to use an external 5 volts DC supply normally no ATX, PS_ON, i mean just + and -
How should i connect it to the ethernet board?
+5v source to the +5v Duet pin
GND source to the GND Duet pin
Can i let the PS_ON whit out connect it or should i do a bridge with + or gnd?
Thanks

the ps_on is an outgoing signal to the power supply.
if you dont have it leave it unconnected.

you could also use a relay control to control the mains power to the main psu and turn it on and off with that functionality.
