Redundancy: Dual redundant PSU
Curation Review
✔ Pros:Very high port density for a 1RU switch (56 ports, mixing 2.5G, 5G and 25G); 720 Gbps switching capacity suits multi-gig access and aggregation; Hardware MACsec encryption on all ports; FortiLink integration lets a FortiGate manage it centrally; Dual redundant PSUs; 25G SFP28 uplinks, with backward compatibility for 10G SFP+
✘ Cons:Data-only base model with no PoE, so it cannot power APs or cameras; The FPOE variant costs substantially more; Requires a FortiGate for central management, which adds to total cost of ownership; Pricing and warranty terms vary across resellers (one lists a limited lifetime warranty, another a one-year hardware warranty); Official fortinet.com datasheet could not be retrieved, so specs come from reseller listings and should be verified; One reseller listing gives conflicting figures (1.44 Tbps, 40GbE uplinks) and was disregarded
Stacking support: Not confirmed; no physical stacking documented in sources reviewed
MAC Address Table Size: 32,000 entries
Packet Buffer Size: 2 MB

Management: UniFi Network 8.0.24+
Operating Temperature: -5 to 40u00b0C (23 to 104u00b0F)
Certifications: CE, FCC, IC (one listing states NDAA compliant)
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
