| Product Description |
Cisco C9K-PWR-650WAC-R/2 Full English Official Product Description
Product Overview
The Cisco C9K-PWR-650WAC-R/2 is a hot-swappable, front-to-back airflow 650W secondary redundant AC power supply module built exclusively for Cisco Catalyst 9500 Series fixed-form-factor high-performance switches. It shares identical electrical and mechanical specifications with C9K-PWR-650WAC-R, serving as the secondary power unit deployed in the vacant PSU bay to establish a 1+1 redundant power architecture. This power module provides stable regulated power for switching ASICs, management subsystems, interface modules and internal cooling assemblies, supporting seamless automatic power failover to eliminate single-point power failure risks for aggregation and data center network infrastructure.
Core Technical Specifications
-
Rated Maximum Output Power: 650 Watts
-
AC Input Voltage: Universal 90–264 VAC, 47–63 Hz
-
Input Connector: IEC C14 power inlet
-
Output Rails: 12 VDC main rail plus 12 VDC standby power
-
Energy Efficiency: 80 PLUS Platinum high-efficiency design
-
Airflow Direction: Front-to-back (port side intake, rear exhaust)
-
Form Factor: Config 4 hot-pluggable field-replaceable unit (FRU)
-
Adaptive variable-speed cooling fan controlled by load and ambient temperature
-
Front panel LED indicators for power presence, normal operation and fault alerts
-
Integrated multi-layer protection: overvoltage, overcurrent, short-circuit and overtemperature shutdown
-
Minimum output hold-up time: ≥20ms under typical working load
Hardware Compatibility
Fully compatible with Catalyst 9500 series switches including C9500-32QC, C9500-24Y4C, C9500-48Y4C models. It works paired with C9K-PWR-650WAC-R primary power supply inside the same chassis. This PSU cannot be used on Catalyst 9400 modular chassis or Catalyst 9500X platforms. When redundant power configuration is not implemented, vacant power slots must be covered with C9K-PWR-C4-BLANK filler panels to maintain chassis airflow, thermal balance and EMC compliance. Mixing power supplies with different airflow directions within one rack is not recommended.
Key Features & Benefits
-
Hot-swappable OIR capability: Supports live module replacement without shutting down the switch, minimizing network maintenance downtime.
-
Secondary redundant power design: Achieves seamless automatic power switchover once the primary PSU fails to sustain uninterrupted network services.
-
Platinum high efficiency reduces power consumption and heat dissipation to lower long-term operational costs.
-
Standard front-to-back airflow design consistent with Catalyst 9500 thermal architecture for unified data center cabinet cooling layout.
-
Enterprise-grade hardware construction supporting stable continuous operation under standard data center temperature environments.
-
Real-time power status monitoring and fault reporting via Cisco IOS XE operating system.
Typical Deployment Scenarios
Enterprise campus aggregation layer networks, medium-sized data center top-of-rack switching, carrier Ethernet access nodes, financial, medical and other mission-critical IT infrastructure, applicable for Catalyst 9500 high-density 10G/25G switch deployments requiring high power availability.
Compliance & Certification
Compliant with global electrical safety standards, Class A EMC and EMI specifications, qualified for worldwide commercial enterprise and carrier-grade network deployments.
