Switching Performance and PoE+ Flexibility
To get enough routing capacity, the UniFi Switch device allows traffic to be processed on all ports without any interruption. To simplify your infrastructure, UniFi Switch models are available with 8, 16, 24 or 48 Gigabit Ethernet PoE ports. They are equipped with IEEE 802.3af/at auto-sensing or configurable 24V passive PoE.
The detection of 802.3af/at devices is also automatic. In this case, the UniFi Switch automatically detects 802.3af/at devices so that they receive PoE. For passive 24V PoE devices, you have to manually enable passive 24V PoE.
