CSS326-24G-2S+RM POE

I have CSS326-24G-2S+RM CloudSwitch that is supposed to be powered from PoE on Port1, but whatever I try, it does not power up - it works with external supply only.
I have tried to power it from two different switches that are PoE - able (Dahua and TPLink, both normally supply power to other devices in our network).
I have some other Mikrotik PoE gear
two cAP Lite AP’s works with TPLink switch, but not with Dahua switch
LHG LTE router - works with both TPLink and Dahua switches

I am new to PoE, so I do not know what can be the reason, or what am I missing.

Your switches are likely 802.3at/af Active PoE type switches - which is a common standard that a lot of things use, including some models of mikrotiks.

The CSS326 unfortunately only accepts 24v Passive PoE in. The pinout is different, and voltage is different. Some switches, specifically managed, can be changed to deliver 24v passive out of a certain port so you’d need to look into if your switches can do that. Alternatively, you’d have to use a standard Mikrotik PoE injector and 24v power supply.
