CRS328-24P-4S+RM POE out setting

Hardware MikroTik hardware general

HI,
I would like to know if it is possible to set the output voltage of the CRS328-24P-4S+RM between 12V and 48V, I have a network with 24V AP and 48V telephones and would like to change the current switches with a CRS328-24P-4S+ RM.
Thank you

Your only options are PoE Voltage: Auto, High or Low.

The documentation does say "Some MikroTik PoE-Out devices support the global PoE settings " but the CRS328-24P-4S+RM is not one of these devices.

According to docs, yes:

https://help.mikrotik.com/docs/spaces/ROS/pages/19136769/PoE-Out#PoEOut-PortSettings


poe-voltage (auto | low | high; Default: auto)

A feature that allows us to manually switch between two voltage outputs on PoE-Out ports. It will take effect only on PSE with switchable voltage modes (CRS112-8P-4S-IN, CRS328-24P-4S+RM, netPower 16P, CRS354-48P-4S+2Q+RM).

But it’s 24V/48V, not 12V/48V.

I have one running here and it’s working as expected (one IP Phone, one wAP LTE KIT), in auto mode:

What matters to me is that it is 24/48V and there is the possibility as an alternative. I was thinking of taking two CRs312-8P, one powered by 24 and one powered by 48 to put in the rack, but I think a 24 port would be better as it takes up less space. and does the same thing
so I really think I will mount the crs24 so in the same space I also have more ports available
