What is the difference between the 12 volt and 24 volt power supply?
- Datto Networking Appliances
If you're using the indoor enclosure, you must use the 12-volt power supply as the 24-volt power supply will not fit. For all other installations, especially when using a single-port passive PoE injector, we recommend the 24-volt power supply.
The 8-port and 12-port passive PoE injectors include their own power supply, so you do not need to purchase one separately.
