I have RB5009UPr wont accepts PoE-in. Its connected to cisco 3750x. I know cisco works well as it’s powering up 8 cameras and it can power up to 24 devices.
Wondering if there any setting needed to be enabled on RB5009 as currently PoE Out is set to auto under all infaces?
Same problem.
I noticed only eth1 enables PoE-in. All other interfaces (eth2 to eth8) don´t boot up the router.
Is there anyone using it?
Regards
POE-In is supported only on ether1. The other ports are not hardware wired for it to work. There is a discussion on Reddit about the misleading marketing from MikroTik.
PoE in 802.3af/at (ether1), Mode B (ether2-ether8)
Mode B is pre-standard? I have an Aruba switch which supports 802.3af/at and 802.3af/at + Pre-standard
When pre-std-detect is enabled, power will be delivered on PairA only
Most likely Mode A.
The standard (802.3/at) says that PSE (the Power Supply) PD (Powered Device) must be compatibile with BOTH modes and the PD (Powered Device) PSE (the Power Supply) asks decides for the one or the other.
Mikrotik devices generally use mode B, but per standard the devices 802.3at should accept also mode A.
Yes, my bad 
, I inverted PSE and PD, hopefully corrected now.
