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
Stacking support: Not confirmed; no physical stacking documented in sources reviewed

Curation Review
✔ Pros:Layer 3 switching in a 24-port 1U chassis; 8x 2.5GbE PoE++ ports for multi-gig wireless and workstation uplinks; 400W total PoE budget with up to 60W per port; 2x 10G SFP+ uplinks; 112 Gbps switching capacity and 56 Gbps non-blocking throughput; managed centrally through UniFi Network; list price of $799 USD from Ubiquiti's US store is competitive for L3 PoE++ hardware
✘ Cons:400W total PoE budget is limited if many high-power PoE++ devices are connected at once; No physical stacking documented, so scaling beyond one unit needs separate management; Port breakdown is described inconsistently across retailer listings, so the official Ubiquiti datasheet should be checked; Reseller prices vary widely (about $799 to $951 USD, plus higher regional prices); Independent hands-on reviews with measured performance were not found; Requires UniFi Network 8.0.24 or later for management
