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
PoE Budget: 400 W total (PoE 15.4 W, PoE+ 32 W, PoE++ 60 W per port; 16 PoE++ and 8 PoE+ ports)

Curation Review
✔ Pros:16 PoE++/PoE+ ports and 8 2.5GbE PoE++ ports provide a mix of multi-gig and PoE for access points and cameras; 400 W PoE budget covers typical AP and camera loads; Layer 3 features (inter-VLAN routing, static routes, DHCP server) let it handle routing without a separate router; 112 Gbps switching capacity and 83 Mpps forwarding rate; 2x 10G SFP+ uplinks; LACP, jumbo frames and 1,000 VLANs; 1.3-inch touchscreen LCD for on-device status
✘ Cons:400 W PoE budget is less than the 960 W that all 16 PoE++ ports could draw at full 60 W, so simultaneous full-power loads are limited; only 2 SFP+ uplink ports and no documented stacking; 1.5 MB packet buffer is small for heavy multi-gig traffic; price is high compared with unmanaged or lower-PoE switches; 1U rack-mount chassis needs a rack; no published fan noise or stacking data, and no independent long-term reviews were found
