CP-6823-PWR-NA=: What Powers High-Density Cisco Networks? Specifications, Regional Compliance, and Use Cases Analyzed

​​Core Functionality and Regional Design​​

The ​​CP-6823-PWR-NA=​​ is a ​​6,800W three-phase AC power supply​​ tailored for Cisco Catalyst 6800 and 6500-E series switches in ​​North American markets​​. Engineered to meet strict UL and FCC regulations, it addresses the power demands of high-density networks running PoE++ devices, advanced line cards, and redundancy configurations.

​​Key Technical Specifications​​

• ​​Input Voltage​​: 200–240 VAC, three-phase, 60 Hz (compliant with NA grid standards).
• ​​Output Capacity​​: ​​6,800W total power​​ with ​​4,800W allocated to PoE++/UPoE​​ for endpoints like 802.11ax APs and PTZ cameras.
• ​​Efficiency​​: 94% efficiency at 50% load, certified ​​80 PLUS Titanium​​ and ENERGY STAR®.
• ​​Redundancy​​: Supports ​​N+1 and grid redundancy​​ for uninterrupted operation during power failures.
• ​​Certifications​​: UL 60950-1, FCC Part 15, and RoHS compliant.

​​Addressing Critical User Concerns​​

​​Q: Is the CP-6823-PWR-NA= compatible with older Catalyst 6509-E chassis?​​

Yes, but only with ​​Supervisor Engine 2T or later​​ and Cisco IOS 15.1SY. Legacy supervisor modules may require firmware upgrades.

​​Q: Can it support third-party PoE injectors or splitters?​​

While physically compatible, Cisco restricts ​​power prioritization and monitoring​​ to validated devices. Third-party gear may trigger fault alerts.

​​Primary Deployment Scenarios​​

• ​​Enterprise Data Centers​​: Powers 40/100G line cards for hyperscale virtualization and AI workloads.
• ​​Stadium Networks​​: Delivers PoE++ to 4K/8K video displays and crowd analytics sensors.
• ​​Industrial IoT Hubs​​: Supports ruggedized switches in manufacturing plants with fluctuating power quality.

​​Purchasing and Compliance Guidance​​

For NA-based deployments, the ​​CP-6823-PWR-NA= is available here​​. Ensure your facility’s electrical system includes ​​three-phase circuits rated for 30A per phase​​ and consult licensed electricians for installation to meet NEC standards.

​​Expert Perspective​​

The CP-6823-PWR-NA= solves two critical challenges: regional compliance and power scalability. While its regional lock-in limits global deployments, the unit’s Titanium efficiency can reduce energy costs by 15–20% compared to older Gold-rated PSUs—a win for sustainability mandates. In retrofit projects, I’ve seen it extend the lifespan of Catalyst 6800 chassis by 3–5 years, deferring costly full-system upgrades. For enterprises committed to Cisco ecosystems, this PSU isn’t just hardware; it’s a strategic bridge between legacy infrastructure and next-gen demands.
