Understanding the CAB-AC-16A-SG-JPN=
The CAB-AC-16A-SG-JPN= is a 16-amp AC power cable engineered for Cisco’s high-power devices in Japan. It combines a grounded plug compliant with Japanese electrical standards and robust current handling for energy-intensive equipment like data center switches and servers. Unlike generic cables, it ensures adherence to Japan’s Denan Law and PSE certification requirements, mitigating risks of non-compliance in commercial installations.
Technical Specifications and Regional Compliance
- Current Rating: 16A at 200V AC, optimized for Japan’s 50/60Hz power grids.
- Connectors: IEC 60320 C19 (device end) and Japanese 15A/20A grounded plug (JIS C 8303 standard).
- Compatibility: Designed for Cisco Nexus 9300/9500 chassis, UCS C480 ML servers, and Catalyst 9500H switches.
- Safety Certifications: PSE mark (mandatory in Japan) and IEC 60950-1 for fire/electrical safety.
Key Benefits for Japanese Deployments
- Regulatory Alignment: Addresses Japan’s strict Denan Law mandates for industrial-grade power components.
- High-Current Support: Safely powers devices like Nexus 93180YC-EX switches under peak loads without voltage drops.
- Durability: Reinforced insulation resists wear in high-temperature environments common in Japanese data centers.
For example, a Nexus 9336C-FX2 spine switch operating in a Tokyo colocation facility would require this cable to avoid circuit breaker tripping during traffic spikes.
Common Use Cases
- Enterprise Data Centers: Connects high-density chassis to 200V PDUs in facilities with limited power redundancy.
- AI/ML Workloads: Supports GPU-heavy UCS servers requiring stable 16A feeds.
- Telecom Edge Sites: Powers Catalyst 9500 switches in NTT or KDDI network hubs.
Procurement and Installation Best Practices
The CAB-AC-16A-SG-JPN= is not interchangeable with lower-rated cables (e.g., 10A models) or non-Japanese plugs. Key considerations:
- Confirm facility voltage (200V AC in most Japanese commercial buildings).
- Verify device power supply units (PSUs) support C19 inlets.
For guaranteed compliance, source this cable from authorized suppliers like itmall.sale’s Cisco catalog.
Lessons from On-Ground Implementations
In Osaka-based cloud deployments, I’ve seen misconfigured power cables cause unplanned outages during audits. While the CAB-AC-16A-SG-JPN= solves compliance headaches, its Japan-specific design limits flexibility in multi-region rollouts. Always pair it with Japanese PDUs—retrofitting North American or EU power strips introduces compatibility gaps. For global teams, maintaining region-specific spare inventories is non-negotiable to avoid project delays. This cable is a niche necessity, but indispensable when operating within Japan’s regulatory framework.
