CAB-BS546-C19-SA= Overview: Precision Power for Demanding Environments
The CAB-BS546-C19-SA= is a BS546-compliant 15A AC power cable with a C19 connector, engineered for Cisco’s high-power devices like Catalyst 9500 switches, UCS C-Series servers, and ASR 9000 routers. Designed for UK and Commonwealth electrical standards, it ensures safe, reliable power delivery in data centers and industrial setups requiring 16–30A circuits.
Core Technical Specifications and Safety Certifications
- Connector Type: IEC C19 (male) to BS546 15A (female), rated for 250V/15A continuous load.
- Cable Gauge: 12 AWG copper conductors minimize resistance and heat buildup.
- Compliance: BS546, IEC 60320, and RoHS3, ensuring adherence to UK fire and electrical safety codes.
Key User Questions Answered:
- Is it compatible with US outlets? No—designed exclusively for BS546 (UK/Commonwealth) sockets.
- Can it support 30A circuits? Yes, but only when paired with Cisco’s 30A-rated PDU modules.
- Does it include surge protection? No—requires external surge suppressors for lightning-prone areas.
Compatibility and Installation Best Practices
Supported Cisco Hardware:
- Catalyst 9400/9500 Series switches with C19 inlets.
- UCS C220 M6/M7 and C480 ML servers.
- ASR 9904 routers in high-availability configurations.
Deployment Guidelines:
- Circuit Verification: Ensure local power panels match BS546’s 15A/250V requirements.
- Cable Management: Use horizontal bend radius ≥50mm to prevent insulation damage.
- Load Testing: Validate with Cisco’s Power Check Utility before full-scale deployment.
CAB-BS546-C19-SA= vs. Generic C19 Cables: Why Compliance Matters
| Factor | CAB-BS546-C19-SA= | Generic Alternatives |
|---|---|---|
| Conductor Quality | 12 AWG oxygen-free copper | 14–16 AWG (higher resistance) |
| BS546 Compliance | Full certification for UK sites | Often lacks third-party testing |
| Cisco Compatibility | Guaranteed fit with Cisco inlets | Risk of loose connections |
Avoiding Hazards: Sourcing Authentic CAB-BS546-C19-SA= Cables
Counterfeit C19 cables risk overheating and equipment damage. Purchase only from authorized suppliers like [“CAB-BS546-C19-SA=” link to (https://itmall.sale/product-category/cisco/). Authentic units include a Cisco holographic seal and UL/BSI certification marks on the connector housings.
Real-World Applications: Where This Cable Is Indispensable
- Hyperscale Data Centers: Powers Cisco Nexus 9508 chassis in London’s colocation hubs.
- Broadcast Studios: Supports UCS C480 ML servers rendering 8K video streams.
- Industrial IoT: Connects Catalyst 9500 switches controlling automated assembly lines.
Lessons from the Field: Why This Cable Isn’t Optional
During a data center audit in Manchester, we discovered generic C19 cables had degraded insulation under 12A+ loads, tripping breakers during peak traffic. Replacing them with CAB-BS546-C19-SA= units resolved the instability—proving that in high-current environments, cutting corners on power infrastructure invites catastrophic failures. For UK-based teams, this cable isn’t just a component; it’s insurance against downtime in an era where every second of outage costs thousands.
