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
Stacking Support: No stacking; high availability via Aruba VSX (Virtual Switching Extension)
Form Factor: 1U rack-mountable
Packet Buffer: 16 MB
MAC Table Size: 98,304 entries (per HPE QuickSpecs; some resellers list 14K)
VLANs: 4,096 (802.1Q; reseller-listed, not confirmed in official datasheet)
Power Supplies: Dual redundant PSUs (listed as 2x 400W on JL579A bundle)
Operating System: AOS-CX
Curation Review
✔ Pros:2.5 Tbps switching capacity and 1,905 Mpps forwarding for core/aggregation use; Layer 3 managed switching in a compact 1U chassis; VSX active-active high availability without stacking; Dense 40G QSFP+ uplink options (6x on the 48-port SKUs, 32x on JL579A); 16 MB packet buffer and 98K MAC table suitable for busy campus or data center aggregation; AOS-CX automation and API-driven management; Redundant power supply options for uptime
✘ Cons:No PoE, so it cannot power access points or cameras directly; No stacking support (VSX is required for HA, which adds design complexity); Priced at the high end of enterprise aggregation switches, roughly $20K to $28K per unit at advertised retail; Some SKUs and resellers list it as end-of-life, so confirm current availability with HPE before specifying; Conflicting MAC table and VLAN figures across listings, so verify against the current HPE datasheet before purchase; Price data is from undated or sold-out retailer listings, not verified street pricing
