C9300-48UB-E Switch: What Makes It Unique? Multi-Gig UPOE+ and Why Itmall.sale?

What Is the Cisco C9300-48UB-E?

The ​​C9300-48UB-E​​ is a ​​48-port Multi-Gigabit (1/2.5/5/10G) UPOE+ switch​​ from Cisco’s Catalyst 9300 Series, engineered for ​​high-density, power-intensive environments​​. It merges ​​Multi-Gig speeds​​, ​​UPOE++ (90W per port)​​, and ​​Cisco SD-Access compatibility​​ to future-proof enterprise networks supporting IoT, Wi-Fi 6E, and converged systems.

Core Technical Specifications

• ​​Port Configuration​​: ​​48 x Multi-Gig RJ45 ports​​ (1/2.5/5/10G) + ​​4 x 25G SFP28 uplinks​​.
• ​​UPOE++​​: Delivers ​​90W per port​​ (UPOE++) to power devices like ​​Cisco’s 802.11ax APs, industrial sensors, and AV systems​​ without injectors.
• ​​Performance​​: ​​480 Gbps system capacity​​ with ​​StackWise-1T​​ for seamless multi-swinegration.
• ​​Software Integration​​: Native support for ​​Cisco DNA Center​​ and ​​SD-Access​​ for policy-based automation.

Key Innovations Over Earlier Models

• ​​Multi-Gig Flexibility​​: Supports ​​2.5G, 5G, and 10G over copper​​, eliminating forklift upgrades for Wi-Fi 6/6E or 4K surveillance.
• ​​Enhanced Power Budget​​: ​​1.2kW total PoE budget​​ ensures stable power delivery across all ports.
• ​​Adaptive QoS​​: ​​Dynamic buffering​​ prioritizes traffic for latency-sensitive applications like VoIP and telemedicine.

Ideal Use Cases

• ​​Wi-Fi 6/6E Deployments​​: Powers ​​Cisco’s 9100/9120 APs​​ at full throughput without bottlenecking.
• ​​Smart Factories​​: Drives ​​industrial IoT devices​​ (e.g., robotic arms, PLCs) with ​​Layer 3 segmentation​​.
• ​​Healthcare Networks​​: Supports ​​HD medical imaging systems​​ and ​​real-time patient monitoring​​ with <2ms latency.

How Does It Differ from the C9300-48U-A?

While the ​​48U-A​​ offers ​​1G UPOE+​​, the ​​48UB-E​​ adds ​​Multi-Gig scalability​​ and ​​25G uplinks​​, making it 3-4x faster in uplink-heavy topologies. The 48UB-E also features ​​Cisco’s StackWise-1T​​ (vs. StackWise-320), enabling ​​10.4 Tbps virtual stack bandwidth​​ for hyperscale campus networks.
