Stacking support: No stacking; multi-chassis redundancy via vPC
Form Factor: 1RU
ASIC: Cisco Cloud Scale FX3
Curation Review
✔ Pros:Wire-rate 48x 25G downlinks with 6x 100G uplinks in a compact 1RU chassis; Cisco Cloud Scale FX3 ASIC gives 3.6 Tbps switching capacity and 1.2 Bpps forwarding; Supports both NX-OS and ACI deployment modes for flexible fabric design; Full L3 capability for leaf/top-of-rack data center roles; vPC provides multi-chassis redundancy without stacking; Typically priced well below modular Nexus 9500 platforms for leaf deployments
✘ Cons:No PoE, so it cannot power endpoints and is unsuited to access-layer use; No stacking, so scaling relies on vPC or fabric design; Licensing tiers (NX-OS Essentials/Advantage, ACI subscriptions) add cost and complexity; Downlink port type is listed inconsistently across sellers (SFP28 vs SFP+), so verify optics compatibility before ordering; Uplink capacity is limited to 100G, short of 400G spine-class platforms; Street prices vary widely by condition and bundle, so quotes should be checked with a Cisco partner
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
