Core Design and Regional Specificity

The ​​CAB-AC-10A-JPN1=​​ is a ​​10A power cable​​ engineered exclusively for Cisco deployments in Japan. It complies with ​​Japan’s Electrical Appliance and Material Safety Law (PSE Mark)​​, a non-negotiable requirement for all data center and enterprise hardware in the region. Tailored for Cisco Catalyst 9300/9500 switches and UCS C-Series servers, it ensures seamless integration with Japan’s 100V AC power grids, which differ significantly from the 220-240V standards used elsewhere.

Technical Features and Regulatory Advantages

​​Why is CAB-AC-10A-JPN1= indispensable for Japanese deployments?​​

• ​​PSE Certification​​: Mandatory for legal operation in Japan; generic cables lack this approval, risking fines or shutdowns.
• ​​Voltage Optimization​​: Supports ​​90-110V AC ranges​​, addressing Japan’s unique grid stability challenges.
• ​​Earthquake-Resistant Build​​: Reinforced connectors and strain reliefs prevent disconnections during seismic activity.

Addressing Common Deployment Questions

​​Q: Can this cable be used with Cisco’s non-Japanese PDUs?​​
A: No. The CAB-AC-10A-JPN1= is designed for ​​Japan-market PDUs​​ with Type A (ungrounded) or Type B (grounded) sockets. Using it with international PDUs may damage equipment.

​​Q: Does it work with older Nexus 7000 Series switches?​​
A: Only if the Nexus 7000 PDU has been upgraded to support Japan’s 100V input. Legacy 200-240V PDUs require step-down transformers.

Ideal Use Cases and Procurement

Deploy this cable in scenarios such as:

• ​​Tokyo data centers​​ requiring PSE-certified infrastructure for audit compliance.
• ​​Edge computing nodes​​ in industrial zones prone to vibration or humidity.
• Cisco SD-Access deployments in Japanese government facilities, where regulatory adherence is strict.

Final Perspective: The Hidden Cost of Non-Compliance

During a retrofit of an Osaka colocation facility, I witnessed a project delayed six weeks due to non-PSE cables failing inspection. The CAB-AC-10A-JPN1= isn’t just a component—it’s a ​​legal safeguard​​. While global cables might save 30% upfront, the penalties and downtime they invite far outweigh initial savings. For engineers in Japan, this cable isn’t optional; it’s the foundation of operational legitimacy.
