Amps don't mean a thing without disclosing Volts, Consider Watts instead. 1300mA at 3V is much different than 1300mA at 18V. The mPCI slot (SR5) is 3.3V. Power to the Motherboard is from 12-48V. W=V*A

I am surprised no one has mentioned this. I looked up power consumption
on the SR5 and it shows 800 to 1300 mA each. You state your power supply
is 700mA. I did not look up power consumption for the RB532 but I would
think you would need at least a 3A supply.

So, does anyone know if it looks like I would be fine on the power side
of things?
I have tweaked the ethernet port settings for no gain.

Next step is to get climbing 280ft to replace board, but I'd like to
confirm power first.
