RB5009 does not get the PoE power from the Netgear GSM4210P switch.
The switch is PoE+ capable and supports all necessary standards (802.3at, 802.3af, passive POE, and compatible 802.3at). Different devices work perfectly, including Unifi APs and Raspberry PI.
I also tried different Mikrotik devices that I own, and none of them can use the PoE from this switch - including the first HAP AC and CRS210-8G-2S+IN.
Is Mikrotik PoE+ compatible only with Mikrotik PoE+ switches?
