​​Introduction to the CAB-C19-C20-3M-JP= Power Cable​​

The ​​CAB-C19-C20-3M-JP=​​ is a Cisco-certified, 3-meter AC power cable designed for high-power devices in Japan. Featuring a C19 plug (IEC 60320) and a C20 receptacle, it supports 200–240V/15A power delivery while complying with Japan’s Electrical Appliance and Material Safety Law (PSE certification).

​​Technical Specifications​​

• ​​Voltage​​: 200–240V AC, 50/60Hz (Japan’s dual-frequency grid).
• ​​Connectors​​: C19 (NEMA 6-20P plug) to C20 (IEC 60320 receptacle).
• ​​Certifications​​: PSE (菱形 mark), UL, and Cisco validation.
• ​​Compatibility​​: Cisco UCS C480 M5/M6 servers, Catalyst 9500 switches, and Nexus 9500 chassis.

​​Primary Use Cases​​

• ​​Data Centers​​: Powering UCS C480 servers in Tokyo or Osaka facilities.
• ​​High-Performance Computing​​: Supporting Catalyst 9500 switches in AI/ML clusters.
• ​​Industrial Deployments​​: Energizing Nexus 9500 chassis in manufacturing plants with 200V circuits.

​​User Concerns Addressed​​

​​Can this cable be used outside Japan with adapters?​​

No. The ​​NEMA 6-20P plug​​ is incompatible with non-Japanese outlets. Adapters bypass PSE safety protocols, violating Japan’s compliance standards and risking equipment damage.

​​Is it compatible with older UCS C460 M4 servers?​​

Yes, provided the server’s PSU uses a C20 inlet and operates within 200–240V. Verify the PSU label for voltage range and connector type.

​​How does CAB-C19-C20-3M-JP= differ from C13/C14 cables?​​

The ​​C19/C20​​ pair supports higher current (15A vs. 10A for C13/C14), making it essential for power-hungry devices like blade servers or modular chassis.

​​Do third-party C19-C20 cables meet Japanese regulations?​​

Generic cables often lack ​​PSE certification​​, risking non-compliance fines or voiding Cisco’s warranty. Non-tested cables may also overheat under sustained 15A loads.

​​Procuring Genuine CAB-C19-C20-3M-JP= Cables​​

For guaranteed PSE compliance and safety, purchase from authorized suppliers like ​​itmall.sale’s Cisco product page​​, which offers factory-sealed, warranty-backed units.

​​Engineer’s Insight​​

In Japan’s tightly regulated tech ecosystem, the ​​CAB-C19-C20-3M-JP=​​ isn’t just a power cable—it’s a compliance lifeline. While uncertified alternatives might seem identical, their absence of PSE marks and Cisco’s thermal validation exposes enterprises to legal liabilities and operational hazards. For mission-critical deployments, cutting corners here is akin to gambling with uptime.
