C9300-24UXB-A=: How Does Cisco’s Ultra-High-Power Switch Enable Next-Gen IoT and Multi-Gig Deployments?

Hardware Architecture & Power Specifications

The ​​C9300-24UXB-A=​​ is a Catalyst 9300 series switch optimized for environments requiring extreme Power over Ethernet (PoE) and multi-gigabit speeds. It features ​​24x Multi-Gigabit RJ45 ports​​ (100M/1G/2.5G/5G/10G) with ​​Cisco UPOE++​​, delivering ​​90W per port​​ and a total PoE budget of ​​1,100W​​—enough to power ​​Wi-Fi 7 APs, 4K PTZ cameras with heaters​​, and even small edge servers. The ​​1x modular network slot​​ supports uplinks up to ​​40G QSFP+​​, ensuring backbone readiness for high-density data flows.

Performance & Scalability

• ​​Throughput​​: ​​176 Gbps non-blocking switching capacity​​ handles simultaneous 4K video streams, industrial IoT telemetry, and AR/VR applications without latency spikes.
• ​​Stacking​​: ​​StackWise-1T​​ enables eight switches to operate as a single entity with ​​800Gbps stacking bandwidth​​, ideal for large-scale smart campuses or distributed manufacturing sites.
• ​​Resilience​​: Dual ​​1100W hot-swappable power supplies​​ with N+1 redundancy and ​​EnergyWise Dynamic Power Management​​ ensure uptime in mission-critical environments like hospitals or financial trading floors.

Addressing Deployment Challenges

​​Q: How does it manage power allocation for fluctuating IoT device demands?​​
The switch uses ​​Cisco’s Intelligent Power Monitoring (IPM)​​, which adjusts PoE++ output in real time. For example, a port powering a ​​60W outdoor AP​​ can temporarily boost to 90W during firmware updates while throttling non-essential devices like IP phones.

​​Q: Can it support legacy fiber and modern high-speed uplinks simultaneously?​​
Yes. The modular slot accepts ​​1G/10G/40G modules​​, allowing hybrid connectivity. A common setup uses ​​10G SFP+ for local storage​​ and ​​40G QSFP+ for core network links​​, enabling phased infrastructure upgrades.

Strategic Use Cases

• ​​Smart Cities​​: Powers ​​traffic sensors, emergency call boxes​​, and license plate recognition cameras while prioritizing public safety data via ​​Cisco AVC​​.
• ​​Media Production​​: Supports ​​jumbo frames (9K MTU)​​ for high-resolution video editing workflows and ​​PTPv2​​ synchronization for broadcast-grade timing.
• ​​Retail Edge​​: Secures ​​cashless payment terminals​​ and digital signage with ​​MACsec AES-256​​, ensuring PCI-DSS compliance across all ports.

Procurement & Licensing Considerations

For enterprises needing uncompromised PoE++ and multi-gig flexibility, the [“C9300-24UXB-A=” link to (https://itmall.sale/product-category/cisco/) offers Cisco-validated hardware. Opt for ​​DNA Premier licensing​​ to unlock AI-driven network analytics and ensure firmware compatibility with ​​IOS XE 17.12.4a​​.

​​Personal Insight​​: While the C9300-24UXB-A=’s 90W per port sets a high bar, its true innovation lies in EnergyWise’s granular power redistribution—often underutilized by teams focused solely on peak specs. However, deploying it without Cat6a or better cabling negates its multi-gig advantages, making pre-deployment infrastructure audits essential. For cost-sensitive projects, reserving this model for high-power zones (e.g., surveillance hubs) while using lower-tier switches elsewhere maximizes ROI without sacrificing critical performance.
