Cisco C9K-PWR-650WACL-R Full English Official Product Description
Product Overview
The Cisco C9K-PWR-650WACL-R is a hot-swappable 650W front-to-back airflow AC power supply module designed exclusively for Cisco Catalyst 9500 Series fixed-form-factor high-performance enterprise switches. It serves as an alternate version of C9K-PWR-650WAC-R, delivering regulated 12VDC power to support switch forwarding ASICs, management subsystems, interface modules and internal cooling components. This power unit can operate as a standalone primary power source or pair with an identical PSU to build a 1+1 redundant power architecture for aggregation and data center switching infrastructure.
Core Technical Specifications
-
Rated Maximum Output Power: 650 Watts
-
AC Input Range: Universal 90–264 VAC, 47–63 Hz
-
Input Connector: IEC C14 power inlet
-
Output Rails: 12 VDC main rail + 12 VDC standby power
-
Efficiency Standard: 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 dynamically controlled by load and ambient temperature
-
Front panel LED indicators for power presence, normal running status and fault alarms
-
Integrated multi-layer protection: overvoltage, overcurrent, short-circuit and overtemperature protection
-
Minimum output hold-up time: ≥12ms under full rated load
Difference note vs C9K-PWR-650WAC-R: Lower surge withstand capacity, shorter hold-up time and adjusted over-power protection threshold
Hardware Compatibility
Fully compatible with Catalyst 9500 series switches including C9500-32QC, C9500-24Y4C, C9500-48Y4C models. It supports mixing deployment with C9K-PWR-650WAC-R within the same chassis, though Cisco recommends using matching PSU models for redundant configurations. This power supply cannot be used on Catalyst 9400 modular chassis or Catalyst 9500X platforms. Vacant power bays must be covered withC9K-PWR-C4-BLANKfiller panels to maintain chassis airflow, thermal balance and EMC compliance. Mixing power supplies with different airflow directions within one rack is prohibited.
Key Features & Benefits
-
Hot-swappable OIR capability: Supports live module replacement without shutting down the switch, minimizing network maintenance downtime.
-
1+1 redundant operation support: Automatic seamless power failover to eliminate single-point power failure risks for critical networks.
-
Platinum high efficiency reduces power consumption and thermal output to lower long-term operating costs.
-
Standard front-to-back airflow architecture consistent with Catalyst 9500 thermal design, simplifying unified data center rack cooling planning.
-
Enterprise-grade hardware construction supporting continuous stable operation within standard data center temperature environments.
-
Real-time power status monitoring, fault logging and 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, commercial office IT infrastructure, suitable for Catalyst 9500 high-density 10G/25G switch deployments with non-extreme surge environment requirements.
Compliance & Certification
Compliant with global electrical safety standards, Class A EMC and EMI specifications, qualified for worldwide commercial enterprise network deployments.
