Both came up on a class 3 poe injector and my hasivo multi-gig poe+ switch.yea, tried both. i finally got them to "work" by using a brand new aruba 1960 switch with poe class 6 802.3bt ports. even though the r750 supports
Both had static IP's configured as they weren't sending out DHCP requests.
Reset button fixed that.
One had zone firmware.
logged in with default creds, loaded unleashed and it adopted into my existing network.
I should have taken a screenshot of the zone one... it had something about Access Networks Multimedia Wireless Hub or some other.
made me laugh. jibber-jabber for non-technical wealthy peeps.
The other was unleashed already and adopted but old version so bumped to what I'm running and again done.
nice buy.
