PoE Budget: 400 W total; up to 34.2 W per port (IEEE 802.3af/at)
Max Power Consumption: 550 W
Layer: L3 (limited routing; full routing typically requires an external router)
Stacking Support: Not confirmed in available sources
Form Factor: Rack-mount, 442.4 x 43.7 x 325 mm (approx. 1U)
Curation Review
✔ Pros:Twelve 2.5GbE PoE+ ports plus twelve 1GbE PoE+ ports for mixed multi-gigabit and legacy endpoints; Two 10GbE SFP+ uplinks; 400 W PoE budget suits several PoE+ access points or cameras; Quiet operation and solid build quality reported by users; Layer 3 feature set including IGMP snooping, STP/RSTP, LACP, 802.1X and port isolation; Competitive price for a 2.5GbE PoE+ L3 switch
✘ Cons:Layer 3 routing is limited and mostly superficial, so full routing needs an external router; Limited dynamic routing support reported for the closely related USW-Pro-24-PoE, unverified for this model; Full feature set depends on the UniFi Controller; Stacking support is unconfirmed; Listed as Vintage on Ubiquiti's Japanese store, which may indicate legacy or discontinued status; Few in-depth independent reviews are available

Technical Specifications
Switching Capacity: 56 Gbps (24P-4G) to 128 Gbps (24-port 4x10G) and 104 Gbps (48P-4G) to 176 Gbps (48P-4X); varies by SKU and source
Forwarding Rate: 83.33 Mpps (24P-4G) to 190.4 Mpps (24P-4X); 154.76 Mpps (48P-4G) to 261.9 Mpps (48P-4X); varies by SKU and source
Ports (breakdown): 24 or 48 x 10/100/1000 downlink ports (PoE+ on P models, non-PoE on T models; some 48-port PXG variants add mGig ports) plus 4 fixed uplinks: 4 x 1G SFP (-4G) or 4 x 10G SFP+ (-4X)
PoE Budget: 24P models: about 370 W default, up to about 740 W with redundant PSU; 48P models: about 740 W default, up to about 1440 W with two PSUs (sources conflict, e.g. 600 W and 1 kW PSU options quoted)
Layer: L2/L3: Network Essentials provides L2 switching with basic L3 features; Network Advantage adds full dynamic L3 routing
Stacking support: Yes, StackWise-80 with 80 Gbps stacking bandwidth, up to 8 switches (requires stacking module/kit)
Curation Review
✔ Pros:Cisco StackWise-80 stacking of up to 8 units with 80 Gbps stacking bandwidth; 4x10G SFP+ uplink option for higher-bandwidth aggregation; Full PoE+ (802.3at) on P models with budgets up to roughly 1440 W with redundant power; Two licensing tiers (Network Essentials and Network Advantage) let buyers pay only for needed L3 features; Lower price point than Catalyst 9300 for standard campus access deployments
✘ Cons:Uplinks are fixed with no modular expansion slots, which limits future upgrade paths; Full dynamic L3 routing requires the more expensive Network Advantage license; Stacking needs a separate stacking module and is capped at 8 units; Switching capacity and PoE budgets differ widely between SKUs, making spec comparison and sizing confusing; Lower forwarding performance and feature depth than Catalyst 9300 for aggregation or core roles
