What Is the CAB-C15-AC=?
The CAB-C15-AC= is a high-temperature-rated AC power cable designed for Cisco devices operating in environments where heat dissipation is critical. Featuring an IEC C15 connector (hot condition-rated) on the device end and a regional AC plug on the power source side, it ensures safe power delivery to equipment like Cisco UCS servers, Nexus switches, and PoE-enabled devices that generate significant heat under load.
Key Technical Specifications
- Voltage Rating: 250V AC, 10A
- Connectors: IEC C15 (device) to regional plug (e.g., NEMA 5-15P for North America)
- Temperature Tolerance: Rated for 120°C (vs. 70°C for standard C13 cables)
- Certifications: UL, CSA, CE, and RoHS compliant
- Length: 2 meters (standard for rack deployments)
- Use Case: Ideal for high-density racks, PoE switches, or environments with limited airflow
The Significance of the C15 Connector
The IEC C15 connector on the CAB-C15-AC= is distinguishable from the common C13 by its notched design and higher heat tolerance. This makes it mandatory for devices like Cisco Catalyst 9300 Series switches with PoE+ or UPoE capabilities, which can overheat standard cables. The C15’s 120°C rating prevents insulation melting and reduces fire risks in confined spaces.
Compatible Cisco Hardware
This cable supports Cisco equipment with C16 inlets (the female counterpart to C15), including:
- Cisco Catalyst 9400 Series Switches
- UCS C4800 ML Rack Servers
- ASR 9900 Edge Routers
- Meraki MS390 Switches (with PoE++ support)
Avoid using C13 cables as substitutes—C15/C16 pairing is non-interchangeable for safety reasons.
Installation Guidelines
- Heat Management: Route the cable away from hot exhaust zones in vertical racks.
- Plug Verification: Match the AC plug to local voltage (e.g., 125V in North America, 230V in EU).
- Load Testing: Confirm power draw stays below 10A to avoid degrading insulation over time.

Lessons from the Data Center Trenches
During a PoE camera rollout, I witnessed a C13 cable warp and fail under a Catalyst 9300’s load—despite being “rated” for 10A. The CAB-C15-AC= isn’t just a minor upgrade; it’s a requirement for modern high-power setups. In infrastructure, assuming all cables are equal is a gamble no engineer can afford.
