Cisco C9K-PWR-1600WACR/2 Full English Official Product Description
Product Overview
The Cisco C9K-PWR-1600WACR/2 is a hot-swappable, front-to-back airflow 1600W secondary redundant AC power supply module developed exclusively for Cisco Catalyst 9500 Series high-performance enterprise switches. It shares identical electrical and mechanical specifications with primary unitC9K-PWR-1600WAC-R. Deployed as the secondary PSU, it establishes a 1+1 load-sharing redundant power architecture together with the primary power module. This high-capacity power unit supplies stable regulated 12VDC power to switching ASICs, management subsystems, high-density 25G/40G/100G interface modules and internal cooling assemblies, supporting automatic seamless power failover to eliminate single-point power outages for core and aggregation switching infrastructure.
Core Technical Specifications
-
Rated Maximum Output Power: 1600 Watts
-
AC Input Voltage: Dual range 90–140 VAC and 180–264 VAC, 47–63 Hz
-
Input Connector: IEC C16 power inlet
-
Output Rails: Main 12VDC @133A + 12VDC standby rail @3A
-
Energy Efficiency: 80 PLUS Platinum high-efficiency design; typical efficiency up to 94% at 230VAC 50% load
-
Airflow Direction: Front-to-back (port side intake, rear exhaust)
-
Form Factor: Config 4 hot-pluggable field-replaceable unit (FRU) with OIR support
-
Adaptive variable-speed cooling fan dynamically regulated by ambient temperature and power load
-
Front panel LED indicators for power presence, normal operation and fault alarms
-
Integrated multi-layer protection: overvoltage, overcurrent, short-circuit and overtemperature shutdown
-
Minimum output hold-up time: ≥20ms under full rated load
Hardware Compatibility
Fully compatible with Catalyst 9500 fixed-form-factor switches including C9500-32C, C9500-32QC, C9500-24Y4C, C9500-48Y4C. It operates paired with C9K-PWR-1600WAC-R primary power supply within the same chassis. Mixed installation with other wattage PSU models is physically allowed but not recommended by Cisco for redundant configurations. This power supply cannot be used on Catalyst 9400 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 inconsistent 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.
-
Secondary redundant power design: Executes instant automatic power switchover upon primary PSU failure to maintain continuous network services.
-
Platinum high efficiency reduces power consumption and heat dissipation, cutting long-term data center operational costs.
-
High 1600W power capacity fully satisfies power requirements of high-density multi-rate port configurations on Catalyst 9500 switches.
-
Standard front-to-back airflow architecture consistent with Catalyst 9500 thermal layout, simplifying uniform data center rack cooling planning.
-
Real-time power status monitoring, fault logging and status reporting via Cisco IOS XE operating system.
Typical Deployment Scenarios
Enterprise campus core and aggregation layer networks, medium and large data center top-of-rack high-speed switching, carrier Ethernet aggregation nodes, financial, healthcare and other mission-critical IT infrastructure for Catalyst 9500 high-density multi-gigabit 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.
Important Note
C9K-PWR-1600WAC-R = primary AC power supply;
C9K-PWR-1600WACR/2 = secondary redundant AC power supply with fully identical hardware specifications for dual redundant deployments.
