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.

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.
