What is the C9K-PWR-CAB-AC-US=? Cisco’s NEMA-Compliant AC Power Cable for Catalyst 9000 Series Safety and US Grid Compatibility

Overview of the C9K-PWR-CAB-AC-US=

The ​​C9K-PWR-CAB-AC-US=​​ is a ​​region-specific AC power cable​​ engineered for Cisco Catalyst 9300, 9400, and 9500 Series switches deployed in the United States. As confirmed on Cisco.com, this cable adheres to ​​NEMA 5-15P standards​​, ensuring compliance with U.S. electrical codes and safe connectivity to 120V/240V outlets in commercial and industrial settings.

Core Technical Specifications

• ​​Plug Type​​: ​​NEMA 5-15P​​ (3-prong, 15A/125V), compatible with standard U.S. wall outlets and PDUs.
• ​​Cable Length​​: 6 feet (1.8 meters), providing flexibility for rack installations and cable management.
• ​​Certifications​​: UL/CSA safety certified, meeting ​​NFPA 70 (NEC)​​ requirements for commercial electrical systems.
• ​​Compatibility​​: Designed for Catalyst 9000 Series switches using ​​C9K-PWR-XXXX​​ AC power supplies.

Addressing Key User Concerns

​​Q: Can this cable be used with 240V circuits?​​
Yes. The NEMA 5-15P plug supports dual-voltage inputs (100–240V), but ensure local circuits match the switch PSU’s voltage rating.

​​Q: Does it work with non-Cisco equipment?​​
No. The connector is proprietary to Catalyst 9000 PSUs. For third-party devices, use manufacturer-recommended cables.

​​Q: Are third-party alternatives safe?​​
Cisco.com warns that uncertified cables risk ​​voiding warranties​​, overheating, or violating OSHA/NFPA safety codes.

Use Cases Highlighted by Cisco.com

• ​​Corporate Data Centers​​: Safely powers Catalyst 9500 core switches handling high-throughput traffic.
• ​​Healthcare Facilities​​: Meets fire safety standards for switches supporting critical medical IoT devices.
• ​​Education Campuses​​: Deploys Catalyst 9300 switches in lecture halls with NEC-compliant infrastructure.

Final Perspective

In my years overseeing data center builds, I’ve seen “trivial” components like power cables cause catastrophic failures. The C9K-PWR-CAB-AC-US= might seem mundane, but its UL/CSA certification and precise fit eliminate guesswork in compliance-heavy environments. While cheaper knockoffs exist, the risk of frying a $20k switch—or worse, failing an insurance inspection—makes this cable a non-negotiable safeguard. For U.S. IT teams, it’s not just a cable; it’s a liability shield.
