EAP225 not working with a POE+ switch
I wanted to learn about installing AP's so I purchased an EAP225 Indoor Ceiling AP and a Steamemo 5-port POE+ unmanaged switch from Amazon. To configure the EAP225, I used the passive POE injector that it came with and everything went great. When I mounted the EAP225 and plugged it into the POE+ switch I did not get any power to the AP. I tried all of the Ethernet connections on the switch and swapped out cables but nothing worked. The POE+ switch works fine with a VoIP phone.
I scanned the Internet (including this forum) looking for help. Most of the posts suggested doing what I already did. However, I ran into an Youtube video (https://www.youtube.com/watch?v=mUWJ_lbMt8U) where the author claims that the EAP225 does not work with POE+ switches because it only checks for power on 2 of the twisted pairs of wires where the POE+ switches checks on all 4 twisted pairs. Thus, when the POE+ switch is trying to handshake with the EAP225, it fails because it does not get the proper reply on all of the wires. The video was talking about the EAP225 outdoor model, but I am assuming that the outdoor and indoor models use the same handshake (could be a bad assumption).
Does this explanation make sense as to why my EAP225 does not receive power from my POE+ switch? If not, can you provide something else I can try? I do not have a regular POE switch, otherwise I would test out this theory myself.
Thanks!
