Cisco C9K-PWR-930WDC-R Full English Official Product Description
Product Overview
The Cisco C9K-PWR-930WDC-R is a hot-swappable, front-to-back airflow 930W primary DC-input power supply module engineered exclusively for Cisco Catalyst 9500 Series fixed-form-factor enterprise switches. Optimized for standard -48VDC telecom power infrastructure, this field-replaceable unit delivers stable regulated 12VDC power to drive switching ASICs, management controllers, multi-rate interface modules and internal cooling subsystems. The unit can operate independently as the primary power source or pair with the matching secondary redundant moduleC9K-PWR-930WDC-R/2to establish a 1+1 load-sharing redundant power architecture, eliminating single-point power failure risks for carrier, industrial and enterprise aggregation switching environments.
Core Technical Specifications
-
Rated Maximum Output Power: 930 Watts
-
DC Input Voltage Range: -40 VDC to -72 VDC (nominal -48 VDC telecom power)
-
Max Input Current: 23A at full rated load under -48VDC
-
DC Input Interface: Dedicated DC terminal connector for negative DC power wiring
-
Output Rails: Main 12VDC @54A + auxiliary 12VDC standby rail @3A
-
Energy Efficiency: 80 PLUS Platinum rated; typical efficiency reaches 92% at 50% load
-
Airflow Direction: Front-to-back (port-side intake, rear exhaust)
-
Form Factor: Config 4 hot-pluggable FRU supporting OIR (Online Insertion and Removal)
-
Adaptive variable-speed cooling fan dynamically controlled by ambient temperature and power load
-
Front panel LED indicators: Power presence, normal operation status and fault alarms
-
Built-in multi-layer protection: overvoltage, overcurrent, short-circuit and overtemperature shutdown
-
Minimum output hold-up time: ≥8ms under 50% operating load
Hardware Compatibility
Fully compatible with Catalyst 9500 series switches including C9500-16X, C9500-40X, C9500-12Q, C9500-24Q models. The switch chassis supports flexible mixed deployments: dual DC, dual AC, or one AC PSU plus one DC PSU. Cisco recommends deploying identical PSU variants for redundant configurations. This power supply cannot be installed 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 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.
-
Telecom-grade negative DC input, perfectly suited for carrier central offices, transportation and industrial sites equipped with -48V DC power plants.
-
1+1 load-sharing redundancy enables seamless automatic power failover to guarantee uninterrupted network services.
-
Platinum high efficiency reduces power consumption and heat dissipation to lower long-term operational costs.
-
Compact 930W power capacity satisfies standard power requirements of mid-density multi-rate port configurations on Catalyst 9500 switches.
-
Standard front-to-back airflow architecture consistent with Catalyst 9500 thermal design, simplifying unified rack cooling layout planning.
-
Real-time power monitoring, fault logging and status reporting via Cisco IOS XE operating system.
Typical Deployment Scenarios
Carrier Ethernet access and aggregation nodes, industrial network facilities, enterprise campus aggregation layer networks, remote equipment rooms equipped with DC telecom power, and mission-critical infrastructure requiring high power availability for Catalyst 9500 mid-density multi-gigabit switch platforms.
Compliance & Certification
Compliant with global electrical safety standards, NEBS specifications, Class A EMC and EMI requirements, qualified for worldwide carrier-grade and commercial enterprise network deployments.
Important Note
C9K-PWR-930WDC-R = primary DC power supply;
C9K-PWR-930WDC-R/2 = secondary redundant DC power supply with identical hardware specifications for dual redundant deployments.
This is DC-input module; do not connect directly to commercial AC mains.
