Cisco C9300L-48UXG4X-10E: How Does It Future-Proof High-Density Multi-Gig and UPOE++ Networks?

Core Hardware and Port Architecture

The ​​Cisco Catalyst 9300L-48UXG4X-10E​​ is a ​​48-port multi-Gigabit Layer 3 switch​​ engineered for environments demanding ​​simultaneous high-speed data and ultra-high-power device connectivity​​. It features ​​48x 1G/2.5G/5GBase-T UPOE++ ports​​ and ​​4x 10G SFP+ uplinks​​, backed by a ​​1,000W AC power supply​​. Running ​​Cisco IOS XE​​, it supports advanced automation, ​​StackWise-320​​, and granular network segmentation.

UPOE++ and Multi-Gig Performance

• ​​UPOE++ (IEEE 802.3bt)​​: Delivers ​​90W per port​​ to power devices like ​​Wi-Fi 7 access points​​, ​​AI-powered surveillance systems​​, and ​​industrial robotics​​.
• ​​Multi-Gig Flexibility​​: Auto-negotiates ​​1G, 2.5G, or 5G speeds​​ per port, ensuring compatibility with legacy and next-gen devices.

Scalability and Stacking Capabilities

• ​​StackWise-320​​: Combine up to 8 switches into a single stack with ​​640 Gbps stacking bandwidth​​, ideal for large campuses or smart cities.
• ​​Switching Capacity​​: 116 Gbps throughput handles bandwidth-heavy traffic from 4K/8K video streams or real-time IoT analytics.

Security and Traffic Prioritization

• ​​Cisco TrustSec®​​: Implements ​​software-defined segmentation​​ to isolate OT/IoT devices from critical infrastructure.
• ​​Application Visibility and Control (AVC)​​: Identifies and prioritizes latency-sensitive applications like VoIP or telemedicine traffic.

Target Deployment Scenarios

This switch excels in ​​smart hospitals​​, ​​industrial IoT hubs​​, or ​​enterprise campuses​​ where multi-Gig speeds and UPOE++ are non-negotiable. Its ​​redundant power supply support​​ ensures uptime for mission-critical systems like patient monitors or assembly-line robots.

Licensing and Warranty

• ​​Cisco DNA Advantage​​: Includes ​​SD-Access​​, ​​AI Endpoint Analytics​​, and ​​ThousandEyes​​ for end-to-end network insights.
• ​​Enhanced Limited Lifetime Warranty (ELLW)​​: Extends hardware coverage to 10 years with 24/7 TAC support for critical deployments.

Cost vs. Long-Term ROI

While the upfront cost is significant, the ​​C9300L-48UXG4X-10E​​ eliminates the need for costly midspans and external injectors. Its ​​5GBase-T readiness​​ and ​​10G uplinks​​ ensure compatibility with emerging standards like Wi-Fi 7 and 40G backbone upgrades.
