I think you'll find that Atlas does in fact have provision for such
a switch - look for the pwr on pair markings in the top corner of
the board above the ATX connector. I do have a toggle switch wired
to this dating back to when I was using a standard PC PSU which
required this switching. I can't remember if this was an issue when
I first started using the PICO unit it may be that the switch just
happens to be 'on' and I never thought about it :) I'll experiment
with it later and verify that it has impact or not on using the PICO
unit. Others may feel free to comment if they already know if this
is required with the PICO unit.<br>
