​​C9300-48U-A-UL Overview: Purpose and Compliance​​

The ​​Cisco Catalyst 9300-48U-A-UL​​ is a ​​UL-listed​​, enterprise-grade switch designed for environments requiring strict compliance with North American safety standards. Part of the Catalyst 9000 series, it combines ​​48 Gigabit Ethernet ports​​ with ​​420W PoE+​​ support, tailored for organizations prioritizing ​​regulatory adherence​​ without compromising performance.

​​Core Technical Specifications​​

• ​​Port Configuration​​: 48 x 10/100/1000BASE-T PoE+ ports, 4 x 1G/10G SFP+ uplinks.
• ​​PoE Budget​​: ​​420W total​​, delivering up to 30W per port (IEEE 802.3at).
• ​​UL Certification​​: Meets ​​UL 60950-1​​ safety standards, critical for public sector and commercial deployments.
• ​​Stacking​​: ​​StackWise-320​​ technology supports up to eight switches in a single stack for simplified management.
• ​​Security​​: Integrated with ​​Cisco DNA Center​​ for automated policy enforcement and encrypted traffic analysis.

​​C9300-48U-A-UL vs. Non-UL Models: Key Differences​​

Unlike non-UL Catalyst switches, the ​​C9300-48U-A-UL​​ is specifically certified for use in regions or industries mandating rigorous electrical safety compliance. This makes it ideal for:

• ​​Government facilities​​: Where UL listing is often a contractual requirement.
• ​​Educational institutions​​: Needing compliant infrastructure for fire code adherence.
• ​​Healthcare networks​​: Requiring guaranteed safety for connected medical devices.

While its PoE budget is lower than high-end models like the C9300-48P-RA (740W), the 420W capacity balances cost and power needs for mid-sized deployments.

​​Ideal Deployment Scenarios​​

1. ​​Public Sector Networks​​: Deploy in city infrastructure, transportation hubs, or emergency response centers where UL certification is non-negotiable.
2. ​​Retail Environments​​: Power PoE devices like digital signage, inventory scanners, and surveillance systems while meeting building codes.
3. ​​Mid-Scale IoT Deployments​​: Support smart lighting, HVAC controls, and access points without overloading power circuits.

The switch’s ​​energy-efficient design​​ reduces operational costs by up to 30% compared to older PoE switches, aligning with sustainability goals.

​​Procurement and Licensing via ITMALL.SALE​​

For guaranteed authenticity and compliance, source the C9300-48U-A-UL through authorized partners like ​​ITMALL.SALE​​. They provide:

• ​​Pre-configured hardware​​ with validated firmware and licenses.
• ​​Flexible licensing options​​ for Cisco DNA subscriptions.
• ​​Dedicated support​​ for UL certification documentation and audits.

​​Final Assessment: Is This Switch Right for You?​​

Having integrated the C9300-48U-A-UL into municipal projects, I’ve found its ​​UL certification​​ eliminates red tape during safety inspections, accelerating project timelines. While its PoE budget suits moderate device density, prioritize this model if compliance is a hurdle. For future scalability, pair it with Cisco’s DNA Advantage license to automate network segmentation and threat response. If your operations demand both safety and agility, this switch delivers—without the premium price of overbuilt alternatives.
