Field Notice: FN70184 - C9410R and C9407R Chassis Power Cable – Incorrect Rating for Some U.S. Uses - Hardware Upgrade Required

A system error allowed a limited number of customers to order an incorrect power cable with their Catalyst 9400 10-slot and 7-slot switches. This option was incorrectly available with the 3200W AC power supply.

Due to an incorrect configuration of the ordering tool, customer choices for the power cable included item CAB-US515P-C19-US (NEMA 5-15 to IEC-C19 13ft US), which is not suitably rated for the 3200W AC power supply.

If the chassis configuration is such that high-load current is required from the power supply, use of the CAB-US515P-C19-US power cable is not designed or approved to support the required current rating. Use of the incorrect power cable under such conditions could potentially result in damage to the power cord from abnormal heating.

Cisco requires that affected customers replace the power cord CAB-US515P-C19-US with a suitably rated power cord, CAB-US520-C19-US=. Customers can order the replacement power cord through the standard RMA process using normal service support channels. 

Customers can reach out to the Cisco Technical Assistance Center (TAC) or their Account team for any assistance.

Notes:

• The number of replacement power cables ordered should equal the number of power supplies in the chassis.
• The customer is requested to dispose of any incorrect CAB-US515P-C19-US cables or return them to Cisco in order to avoid inadvertent use of the impacted cable in the future.

Your product might be affected if both of these conditions are met.

• Condition 1: The chassis serial number is listed in the affected Serial Number Verification Tool.

  The chassis serial number can be identified via the show inventory command as shown in this example.
