Understanding the CAB-250V-10A-IS=
The Cisco CAB-250V-10A-IS= is a 10-amp, 250V AC power cable engineered for Cisco’s high-power networking and data center equipment. Designed to meet stringent safety and durability standards, it ensures reliable power delivery in environments where voltage stability and fire resistance are non-negotiable.
Core Technical Specifications
- Connectors: IEC 60320 C15 (device-side) to C16 (outlet-side), rated for 250V/10A continuous load.
- Temperature Tolerance: 105°C-rated jacket (IEC 60335-1 compliant), preventing melting in high-heat environments.
- Length: 2 meters (6.56 feet), balancing reach and minimal voltage drop.
- Compatibility: Certified for Cisco UCS servers, Catalyst 9500 switches, and ASR 9000 routers with C15/C16 inlets.
Key Applications and Use Cases
| Scenario | Purpose |
|---|---|
| Data Center Racks | Powers high-density PoE++ switches like C9300-48UXM. |
| Industrial Deployments | Resists oil, dust, and vibration in factory settings. |
| Redundant Power Systems | Connects to PDUs in N+1 power setups without overheating. |
CAB-250V-10A-IS= vs. Generic C15/C16 Cables
| Factor | CAB-250V-10A-IS= | Generic Cable |
|---|---|---|
| Safety Certification | UL/CE/TUV certified | Often lacks multi-region approvals |
| Jacket Material | Flame-retardant PVC (FT4 rated) | Standard PVC (higher flammability) |
| Warranty Compliance | Maintains Cisco device warranties | May void warranties |
Installation and Maintenance Best Practices
- Avoid Daisy-Chaining: Directly connect to a PDU or UPS; power strips are not recommended for 10A loads.
- Strain Relief: Use cable clamps to prevent connector damage in vibrating environments.
- Inspection Routine: Check for jacket cracks or discoloration every 6 months in high-heat zones.
Cost vs. Risk Considerations
While third-party cables are cheaper, the CAB-250V-10A-IS= eliminates risks like thermal runaway or compliance violations. For enterprises seeking cost savings without compromising safety, certified refurbished units are available through the “CAB-250V-10A-IS=” link, which includes UL recertification and a 90-day warranty.
Lessons from High-Stakes Environments
During a refinery network upgrade, generic cables failed under intermittent 9A loads, tripping breakers and causing switch reboots. Replacing them with CAB-250V-10A-IS= cables resolved the instability—underscoring that in mission-critical setups, every component must exceed operational demands. For engineers, specifying this cable isn’t about cost—it’s about eliminating single points of failure in the power chain.
