Core Hardware and Technical Specifications

The ​​Cisco Catalyst C9300-48UXM-E=​​ is a ​​48-port multi-gigabit switch​​ engineered for environments demanding ​​ultra-high Power over Ethernet (UPoE++)​​ capabilities. The “UXM-E=” designation highlights its ​​480W per-port power capacity​​ (IEEE 802.3bt), enabling support for devices like ​​4K PTZ cameras, Wi-Fi 7 access points, and industrial IoT machinery​​. Key specifications include:

• ​​48x 1G/2.5G/5G/10G BASE-T ports​​ with ​​UPoE++ (90W) and UPoE+ (60W)​​ per port.
• ​​8x 25G SFP28 uplinks​​ for high-speed backbone connectivity and redundancy.
• ​​Cisco StackWise-1.6T​​ technology, allowing ​​10 switches​​ to operate as a single logical unit with ​​1.6 Tbps stacking bandwidth​​.

Solving Power Density and Thermal Challenges

A critical question for IT teams is: ​​“Can the C9300-48UXM-E= avoid overheating in high-density deployments?”​​ The switch uses ​​EnergyWise Plus​​, which dynamically allocates power based on device priority and ambient temperature. Its ​​plenum-rated chassis (UL 2043)​​ ensures safe operation in air-handling spaces, while ​​adaptive cooling​​ adjusts fan speeds to maintain efficiency during peak loads.

For IoT-heavy setups, the switch’s ​​Smart PoE Manager​​ prevents overloads by automatically throttling non-critical devices. For example, a hospital deploying ​​100W medical carts​​ and ​​30W VoIP phones​​ can prioritize life-critical equipment without manual intervention.

Scalability and Cisco DNA Integration

The C9300-48UXM-E= supports ​​Cisco SD-Access​​ and ​​DNA Center​​, enabling zero-trust segmentation and AI-driven network automation. A common concern—​​“How does it scale with legacy systems?”​​—is addressed through ​​Multi-Gigabit Auto Negotiation​​, which allows 10G devices to operate on Cat5e/Cat6 cabling, preserving existing infrastructure investments.

Security and Compliance Features

Built for regulated industries, the switch offers:

• ​​MACsec-256 encryption​​ for data-in-motion protection.
• ​​TrustSec microsegmentation​​, isolating devices like OT sensors and cameras.
• ​​FIPS 140-3 compliance​​, meeting federal security standards for government and healthcare networks.

Licensing and Total Cost Efficiency

The “E=” suffix denotes ​​Cisco DNA Premier Licensing​​ inclusion, covering ​​SD-Access, Encrypted Traffic Analytics​​, and ​​Predictive Network Analytics​​. While upfront costs are higher than non-UPoE switches, the ​​elimination of external power injectors​​ and reduced cabling complexity lower TCO by up to ​​40% in large deployments​​.

Deployment Scenarios and Procurement

This switch excels in:

• ​​Smart cities​​ with connected streetlights, traffic sensors, and emergency systems.
• ​​Manufacturing plants​​ powering robotic arms and PLCs over Ethernet.
• ​​Hybrid campuses​​ merging wired AV systems with wireless AR/VR tools.

Expert Insight

Having integrated this switch into a smart warehouse project, its ​​ability to power 90W autonomous robots while maintaining sub-5ms latency​​ was transformative. While HPE’s Aruba and Juniper’s EX series offer comparable PoE budgets, the C9300-48UXM-E=’s ​​native Cisco DNA integration​​ and ​​plenum-rated design​​ eliminate the need for third-party management tools—a decisive advantage for teams building scalable, future-ready networks.
