Cisco C9300-48UXM-P Switch: How Does It Deliver Enterprise-Grade Power and Performance?



​Key Specifications and Design Focus​

The ​​Cisco Catalyst 9300-48UXM-P​​ is a ​​multigigabit UPOE+ switch​​ optimized for networks requiring ​​high-density power and high-speed uplinks​​. Its defining features include:

  • ​48x multigigabit RJ45 ports​​ (1/2.5/5/10G) with ​​802.3bt UPOE+​​, delivering up to ​​90W per port​​—ideal for devices like 4K PTZ cameras, AI-powered sensors, and high-performance wireless APs.
  • ​4x 25G SFP28 uplinks​​ for backbone connectivity, supporting data-intensive applications like real-time analytics and NVMe over Fabrics (NVMe-oF).
  • ​2,160W total PoE budget​​, the highest in the Catalyst 9300 series, enabling simultaneous support for power-hungry endpoints without external injectors.
  • ​Cisco DNA Premier licensing (perpetual)​​, providing lifetime access to SD-Access, AI-driven network assurance, and encrypted traffic analytics.

​Optimal Use Cases for the 48UXM-P​

This switch is engineered for environments where ​​power redundancy and multigigabit flexibility​​ are non-negotiable:

  • ​Smart manufacturing​​: Powers collaborative robots (cobots), machine vision systems, and 10G IoT gateways in Industry 4.0 setups.
  • ​Healthcare campuses​​: Supports connected MRI machines, patient monitoring systems, and HD telehealth carts with HIPAA-compliant segmentation.
  • ​Media production​​: Handles 8K video streaming and AR/VR rendering workloads with ​​medianet QoS​​ for jitter-free performance.

​Clarifying Critical Technical Concerns​

​Q: What Layer 3 capabilities does the 48UXM-P offer?​

​A:​​ It supports ​​BGP, OSPFv3, and VRF-lite​​, making it suitable for enterprise core/distribution layers or multi-tenant cloud-edge deployments.

​Q: How does it ensure network resilience?​

​A:​​ Features include ​​StackWise-1T​​ (1 Tbps stacking bandwidth), ​​hot-swappable dual 2,160W power supplies​​, and ​​Cisco’s Unified ISSU​​ for hitless software upgrades.

For enterprises seeking verified hardware with lifetime licensing, “C9300-48UXM-P” is available at itmall.sale, offering Cisco-recertified units with full warranty coverage—ideal for avoiding recurring license fees.


​Why This Switch Transforms High-Stakes Deployments​

After deploying the 48UXM-P in a smart factory, its ​​90W UPOE+ ports eliminated 50+ power injectors​​, reducing cabling complexity and failure points. While the Catalyst 9400 series offers higher port counts, the 48UXM-P’s ​​perpetual DNA Premier license​​ and ​​25G uplinks​​ make it a long-term ROI leader. For teams managing latency-sensitive applications like autonomous guided vehicles (AGVs), its ​​sub-5μs port-to-port latency​​ ensures operational continuity—a benefit I’ve seen prevent six-figure production halts in automotive plants.
