Hello
i just brought few power box pro and i want to power up one power beam & 3 Base box from it but i got only single 48v space at this site.
as per DS of power box pro " Ethernet ports 2-5 can power other PoE capable devices with the same voltage as applied to the unit "
i don’t want to blow my power beam & base box with 48v so i was hoping if there is any way to step down 48 v to 24 v on Port 2-5
Unfortunately not. The specifications say:
Ethernet ports 2-5 can power other PoE capable devices with the same voltage as applied to the unit.
You could use something like this on those ports:

Although that might not be too practical if everything is mounted externally and you would need 4 of them. You could use it on the input to the PowerBox - but it only puts out 24V 1A and you need more power than that. Probably best to take your 48V supply and use a DC-DC converter that brings the PowerBox input down to 24V. Something like this:
