to increase reliability on my new ccr1036 router, I decided to add a second 24v psu and isolate the two with rectifier diodes. The factory PSU puts out about 24v, after the diode drop it's about 23 and change, I installed a second psu and adjusted the output to 22v or about 21 and change after the diode.
I installed the router and started monitoring the reported voltage by SNMP logging, I noticed it started out at 23v and then has been slowly jumping down and back up to 22v any idea why it wouldn't just keep taking power from the source with the highest voltage? Is this going to be a problem? I was hoping to monitor for main psu failure by sending an alert below 23v which would tell me if the main PSU failed but for some reason this isn't working as planned...
