Fuse for MBX Mini Dual 5G

I’m doing an MBX Mini 12v install and I’m trying to figure out which fuse to use. The specs only show max amp draw, which I presume is while the unit is running on its power supply with PoE enabled. Has anyone installed one of these on 12v and can make a recommendation?

45W max draw. ~4A @ 12V. Fuse at 5A.

Would you share what the config’s would be on the port to allow traffic?

I’m not configuring the ports, I’m only doing the hardware install.
