Description

Cisco PWR-C4-950WAC-R 950W AC Power Supply Module

Product Dimensions：

The Cisco PWR-C4-950WAC-R is a high-efficiency, hot-swappable AC power supply module designed primarily for Cisco’s enterprise-class access switching platforms, specifically the Cisco Catalyst 9400 Series switches.

The “-R” suffix indicates a Rear-to-Front (Port-Side Intake) airflow configuration, which is critical for specific data center and enterprise rack thermal management layouts.

Product Detailed Description

The PWR-C4-950WAC-R provides up to 950 watts of clean DC power to the switch chassis, supporting the operational needs of the supervisor engine, line cards, and Power over Ethernet (PoE/PoE+/UPOE) demands. It functions as a redundant power source when paired with multiple power modules in a Catalyst 9400 chassis, enabling N+1 or N+N power redundancy modes to guarantee maximum system uptime.

Technical Parameters

Product Advantages

• High Efficiency (80 Plus Platinum): Minimizes power loss and reduces heat dissipation within the server closet, translating to lower operational utility costs.
• Hot-Swappability: Can be installed or removed without powering down the switch, allowing maintenance or capacity upgrades without network disruption.
• Thermal Coordination: The Rear-to-Front airflow configuration ensures alignment with modern hot-aisle/cold-aisle data center containment architectures.
• Intelligent Power Management: Interfaces directly with Cisco Cisco IOS-XE software, allowing administrators to monitor power consumption, load sharing, and status thresholds remotely via command line (CLI) or SNMP.

Important Considerations & Precautions

• Airflow Matching: Do not mix PWR-C4-950WAC-R (Rear-to-Front) modules with standard Front-to-Rear airflow power supplies or fan trays in the same chassis. Mismatched airflow will cause localized overheating and trigger thermal shutdowns.
• Voltage Derating: Ensure your electrical infrastructure supplies the correct voltage. While it operates on 110V AC, peak efficiency and maximum capacity are optimized when running on a 200–240V AC circuit.
• Chassis Capacity: Before adding power-hungry PoE devices (like Wi-Fi 6E/7 Access Points or IP cameras), calculate your total budget using the Cisco Power Calculator to verify if additional 950W modules are needed for redundancy.

Product Applications

• Enterprise Core/Aggregation Closets: Providing redundant, mission-critical power to Catalyst 9400 switches routing data across large corporate campuses.
• High-Density PoE Deployments: Powering fleets of IP phones, smart lighting, security systems, and wireless access points in commercial buildings.
• Data Centers & Colocation Facilities: Deployed in networks utilizing hot/cold aisle isolation requiring strict Rear-to-Front cooling compliance.
