Are you sure it is capped at 30V? I am under the impression that it can take 57V
Ah, you're right, hAP ac can indeed take up to 57V.
Guesswork ahead ... There's another possibility as to why hAP ac doesn't power on if RB5009 is powered with 48V: RB5009 might only support 802.3 af/at PoE at high voltages (44+V) while hAP ac is passive (making PoE negotiation fail). ROS upgrade might change this or might not (I wouldn't bet on it).
Product brochure words PoE out as
PoE-Out: Same voltage as supplied, Passive PoE or 802.3af/at (requires 44.0–57.0 V input)
Also mentions "Smart
PoE controller" ... which opens window for software bugs
I think this matter is ready to be escalated to official support ... either via support page
or via e-mail (to email@example.com
). When creating ticket, attach supout.rif file from RB5009 (while it can't power hAP ac) so that they can analyze the problem.
