This may be a noob question, but I have been searching off and on for two days now.
I picked up a used RB2011UAS-2HND-IN unit, but needing to power it.
I understand that ideally the 18POW power supply model would be the best choice.
But what is the difference between RBGPOE and the RBPOE injectors? I can find very little difference about/between them.
What is the difference? When is each used? When is one prefered over another?
Thank you for your time,
