CB-PWRINJ-AR: How Does Cisco’s Power Inject
What Is the CB-PWRINJ-AR? The CB-PWRI...
Core Design and Application
The CAB-C15-ACU= is a Cisco AC power cable engineered for devices operating in high-temperature environments. Its IEC 60320 C15 connector supports equipment requiring elevated thermal tolerance, such as data center switches or industrial-grade routers, where standard C13 cables risk overheating.
Technical Specifications
- Voltage/Current: 10A/250VAC, suitable for global single-phase power systems.
- Cable Length: 6 feet (1.8 meters), balancing reach and clutter reduction in racks.
- Connectors: C15 (device) to C14 (PDU/source), rated for temperatures up to 120°C (248°F).
- Certifications: UL, CE, and RoHS compliant, ensuring fire safety and environmental standards.
Compatibility and Deployment Scenarios
The CAB-C15-ACU= is compatible with:
- Cisco Nexus 9500/9300 Series Switches with high-wattage PSUs.
- UCS C-Series Rack Servers in dense compute environments.
- ASR 9000 Series Routers deployed in industrial or outdoor enclosures.
Typical use cases:
- Data Centers: Powering switches in hot-aisle containment setups.
- Manufacturing: Supporting ruggedized routers in high-ambient-temperature zones.
- Energy Sector: Ensuring reliability in oil/gas or utility control systems.
Advantages Over Standard C13 Cables
- Thermal Resilience: C15 connectors handle 20–30°C higher temperatures than C13, critical for sustained high-load operations.
- Safety: Reduced risk of insulation melting or connector deformation under stress.
- Compliance: Mandatory for Cisco hardware requiring C15 inlets per electrical design specs.
Addressing Critical User Questions
Q: Can this cable replace a C13 in non-high-temp environments?
Yes, but it’s cost-inefficient. Reserve CAB-C15-ACU= for devices explicitly requiring C15 inlets.
Q: Is it backward-compatible with older Catalyst 6500 switches?
Only if retrofitted with C15-compatible PSUs. Legacy 6500s typically use C14/C19 connectors.

Cost vs. Operational Integrity
While generic C15 cables cost 25–40% less, the CAB-C15-ACU= eliminates risks like connector carbonization—a failure I’ve seen in semiconductor fab plants using uncertified parts. One melted cable triggered a $50k downtime event, dwarfing the savings from off-brand alternatives.
In deploying IoT infrastructure for steel mills, I learned that high temps expose every component’s weakest link. The CAB-C15-ACU= isn’t just a cable—it’s a safeguard against thermal degradation that generic suppliers often overlook. For environments where heat is inevitable, compromising here is a gamble with exponential consequences.
