Technical Specifications and Design Features
The CAB-AC-16A-SG-AR= is a Cisco-certified 16A AC power cable engineered for high-power networking and data center equipment. Built with 14AWG copper conductors and a grounded 3-prong plug, it supports 250V/16A power delivery, adhering to IEC 60320 C19/C20 standards. The heat-resistant PVC jacket ensures durability in environments up to 70°C, while its Singapore/Argentina (SG-AR) plug configuration addresses regional power infrastructure requirements.
Key Use Cases and Compatibility
- High-Power Cisco Devices: Ideal for Cisco Nexus 9500/9300 Series switches, ASR 9000 routers, and UCS blade servers demanding 16A+ power input.
- Redundant Power Systems: Integrates seamlessly with dual/quad PSU setups to maintain uptime during grid instability.
- Global Deployments: Compatible with 200-240V power grids common in Southeast Asia and South America, provided local outlets match the plug type.
CAB-AC-16A-SG-AR= vs. Standard Power Cables
| Factor | CAB-AC-16A-SG-AR= | Generic 16A Cables |
|---|---|---|
| Cisco Validation | Full hardware certification | No vendor assurance |
| Current Capacity | Stable 16A at 250V | Often derated above 12A |
| Safety Compliance | IEC/UL/CE certified | Limited or regional-only |
Addressing Common User Concerns
Q: Can this cable support 110V power sources?
A: While technically possible, Cisco recommends using it only with 200-240V systems to avoid inefficiencies and potential overheating.
Q: Is it backward-compatible with 10A Cisco devices?
A: Yes, but ensure the device’s power supply unit (PSU) accepts a C19/C20 connector—common in high-end chassis.
Q: What’s the maximum cable length without voltage drop?
A: For optimal performance, keep under 4 meters. Beyond this, voltage drop may exceed 3% at full load.
Where to Purchase Reliable CAB-AC-16A-SG-AR= Cables
To avoid counterfeit risks, source this cable exclusively from authorized partners like itmall.sale. Third-party alternatives often lack the 14AWG copper gauge or fail Cisco’s rigorous EMI/RFI shielding tests.
Lessons from Field Deployments
The CAB-AC-16A-SG-AR= is non-negotiable for powering mission-critical Cisco hardware in regions with 240V infrastructure. However, its regional plug design limits flexibility—teams operating across multiple countries should stock locale-specific variants. In one project, using uncertified cables caused intermittent PSU failures in Nexus 9508 switches, costing hours of troubleshooting. Always prioritize certified cables for high-current loads; the upfront cost pales against downtime risks.
