I've made some network changes which meant I needed a new switch. Said switch has a UAP-AC-LR on it with PoE injector, so I decided to splash out on Ubiquiti switch, the US-8-60w to be precise, thinking that in future I might be able to put my other AP's onto it too.
I have 2 x LR's purchased about 2 years ago and a Lite in the garage purchased late last year. One thing I didn't count on was Ubiquiti moving away from passive PoE to 802.3af. Plugged it in and set it up and couldn't work out why the LR AP didn't power up, eventually I realised that mine is older and not 802.3af as the UBNT site says.
I had to swap it out with the Lite from the garage. Just remembered I didn't change the injector in the garage, as it's I assume it supports passive and PoE?
