The USW-Pro-24-POE 
Is a configurable Gigabit Layer2 and Layer3 switch with auto-sensing 802.3at PoE+ and 802.3bt PoE++. Sixteen PoE+ and eight PoE++ RJ45 ethernet ports have total 400W PoE budget, and two SFP+ ports offer 10Gbps uplink options. Near-silent cooling and a 1.3" touch LCM.
Note: Layer3 will be included in later software release
Near-Silent Cooling: 
The UniFi Pro PoE Switch can be located in any workspace. Its integrated fans have built-in PWM (Power Management) control, air ducts and covers, and temperature sensors for the best user experience.
Fiber Connectivity:
SFP+ ports enable high-capacity uplinks of up to 10 Gbps, so you can directly connect to a high-performance storage server or deploy a long-distance uplink to another switch.
802.3bt PoE++: 
PoE support simplifies your network infrastructure and cabling. Eight ports offer 802.3bt PoE++ to provide up to 64W of power (per port) to your high‑power PoE devices. Remaining ports offer 802.3af/at PoE. 
Redundant Power Option:
The UniFi Pro PoE Switch supports an external DC input interface, the proprietary USP RPS interface, as a redundant power feature for backup if the internal PSU fails.
Features:
- (8) Gigabit RJ45 802.3bt PoE++ ports
 
- (16) Gigabit RJ45 802.3at PoE+ ports
 
- (2) 10G SFP+ ports
 
- Layer 2 and Layer 3 features
