PoE Budget: C9300X-24HX: 735W to 1,835W (1100W AC PSU, depends on secondary PSU). C9300X-48HXN: 690W to 1,790W (1100W AC). C9300X-48HX: 590W to 1,690W (1100W AC). 24Y and 48TX: no PoE (715W AC PSU)
Stacking: Yes. StackWise-1T, 1 Tbps stacking bandwidth, up to 8 members. Stacks with other 9300X models at StackWise-1T speed; stacks with C9300 models at StackWise-480. Stacking cables: 50 cm, 1 m, 3 m
Data Source: Cisco Catalyst 9300 Series Switches Data Sheet (cisco.com, nb-06-cat9300-ser-data-sheet-cte-en); reseller listings (CDW, CDWG, Avendor, Avoira) for pricing. Official list prices not published in datasheet; price range reflects reseller listings and varies by license tier and port configuration
Curation Review
✔ Pros:Wire-speed nonblocking IPv4 and IPv6 forwarding across all SKUs; StackWise-1T stacking with 1 Tbps bandwidth and up to 8 members; Multigigabit (mGig) UPOE+ downlinks on HX models for 2.5G to 10G wired and high-power Wi-Fi 6/7 AP deployments; 25G SFP28 uplink/downlink options on 12Y and 24Y for modern aggregation; High routing scale (39,000 IPv4 routes) for a switch in this class; Mixed stacking with C9300 at StackWise-480 eases migration; Modular uplinks allow flexible network module upgrades
✘ Cons:Pricing is high, with reseller listings from roughly $10,800 to $29,600+ and wide variance; Full routing (BGP, full OSPF, IS-IS) requires the Network Advantage license, adding recurring subscription cost; IPsec VPN on 9300X requires a separate HSEC key; PoE budget on HX models depends on secondary PSU choice, and no-PoE models (24Y, 48TX) cannot power endpoints; Official SKU-level list prices are not published in the datasheet, making budgeting harder; Higher-speed 25G/10G optics and StackWise-1T cables add cost beyond the base chassis
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
