Defining the 8812-RMBRKT= Hardware Component�...
Overview of the CP-8861-3PW-NA-K9=
The Cisco CP-8861-3PW-NA-K9= is a 6000W, 3-phase AC power supply engineered for Cisco Catalyst 9300 Series Industrial Ethernet (IE) switches. Designed to meet North America’s stringent industrial power standards, it ensures reliability in environments like oil refineries, utilities, and transportation systems where voltage fluctuations and extreme temperatures are common.
Technical Specifications and Rugged Design
- Input Voltage: 347–480 VAC (3-phase), optimized for North American industrial high-voltage grids.
- Output Power: Delivers 6000W at 94% efficiency, minimizing heat generation in sealed enclosures.
- Compatibility: Exclusively supports Catalyst 9300 IE switches (e.g., C9300-24UB, C9300-48UXM) with Enhanced Payload (EP) chassis.
- Environmental Ratings: Operates in -40°C to 75°C and withstands 95% non-condensing humidity, meeting ANSI/IEC 60945 standards for harsh environments.
- Certifications: UL 60950-1, CSA C22.2 No. 60950-1, and ATEX/IECEx Zone 2 compliance for explosive atmospheres.
Key Benefits Over Standard Power Supplies
High Power Density for IoT/OT Convergence: The 6000W output supports simultaneous operation of PoE++ devices (up to 90W per port), 5G small cells, and edge compute modules without derating.
True Grid-to-Switch Protection: Built-in surge suppression (10kV) and harmonic filtering shield connected devices from voltage spikes common in industrial grids.
Modular Redundancy: Enables N+1 or Grid-Redundant (N+G) configurations, allowing failover between two separate power grids—a critical feature for substations or offshore rigs.
Addressing Critical Deployment Questions
Q: Can this power supply replace the CP-8860-3PW-NA-K9= in existing setups?
Yes, but only in Catalyst 9300 IE EP chassis. The CP-8861-3PW-NA-K9= offers 15% higher efficiency and supports Cisco’s latest IOx edge computing applications.
Q: Does it require external transformers for 480V operation?
No. The module accepts 480V input natively, eliminating the need for step-down transformers and reducing installation costs.
Q: How does it handle fan failures in dusty environments?
Dual redundant, IP54-rated fans with dust filters auto-adjust speed based on thermal sensors. Failed fans can be hot-swapped without interrupting operations.
Sourcing Genuine CP-8861-3PW-NA-K9= Modules
For guaranteed safety and performance, procure from trusted suppliers like [“CP-8861-3PW-NA-K9=” link to (https://itmall.sale/product-category/cisco/). Counterfeit units lack hazardous location certifications, risking non-compliance fines or catastrophic failures.
Perspective on Industrial Power Innovation
The CP-8861-3PW-NA-K9= redefines power infrastructure for Industry 4.0, where OT networks demand utility-grade resilience. While its upfront cost is 20–30% higher than standard industrial power supplies, the long-term savings from reduced downtime and simplified grid integration justify the premium. For industries like energy or smart manufacturing, this module isn’t just a component—it’s the backbone of mission-critical connectivity.
