we have some hEX PoE Mikrotik (RB960PGS) devices and we have problems with PoE autodection.
Passive PoE is not a problem. So, if I use 24V 2A adapter, then all devices (cAP) connected to this Mikrotik is powered up in few seconds.
If I use 48V 2A Mikrotik adapter, then autodetect not working correctly. Mikrotik cAP is powered up, but autodetection waiting very long.
I did some this tests (in all cases I use cAP like klient device connected / powered from hEX PoE Mikrotik). Between port unplug and plug to another port I was wating 10-15s:
Mikrotik GM-4820, OUT: 48V/2A via power jack
port 5 - 1min, 40s, 14s
port 4 - 1m 28s, 35s
port 3 - 10s, 27s, 15s
Adapter: SALOM SSW-2159EU, OUT: 48V/0,31A via power jack
port 5 - 17s, 5,23s
port 4 - 2,57s, 25s,
port 3 - 45s, 10s, 11s
Cisco adapter: CP-PWR-CUBE-3 (pn: 341-0206-03 B0) via power jack
port 5 - 41s
port 4 - 13s
port 3 - 33s
Mikrotik GM-4820, OUT: 48V/2A via PoE in
port 5 - 57s, 7s,
port 4 - 10s, 31s, 1m 38s
port 3 - 16s, 23s
24V via power jack (= passive PoE):
port 5 - 2,5s,
port 4 - 2,3s
port 3 - 2,6s
If I connect cAP to the Cisco SG300 or Cisco SG550 poe switch, then cAP is powered via PoE immediately. So no waiting like with hEX PoE.
I tried connect to hEX poe some PoE cam devices and same problem like with cAP. Maybe worse (some IP cam not powered up in 5minutes)
I tried long utp cable, I tried short UTP cable, I tried our UTP structure in building, but problem is still same. Sometime is PoE detected in few seconds, sometime in minutes.
In heX PoE is RoS 6.45.6 (and firmware is in same version). In newer RoS I don't see problems with PoE in changelog.
Should anyone have a tip to solve this problem?
