PoE switch for Raspberry Pi 4 (with SNMP)

Hi,

I'm looking for a switch with power over ethernet (PoE) with SNMP (for STONITH purposes). However, these requirements often come with a price tag above 150 euros. I read that someone setup a high availability cluster with the MikroTik hEX PoE. However, in the specs it says the maximum output per port is 450 mA. While the raspberry pi uses (with the official charger) 5.1V and 3A. So it seems it would be underpowered, which results in an unstable system, if it boots at all.

Does anyone have a recommendation?
