​​What Is the CAB-9K16A-CH=?​​

The ​​CAB-9K16A-CH=​​ is a Cisco-authorized 16A AC power cable engineered for high-current Catalyst 9000 series switches, such as the Catalyst 9500 and 9600 chassis. Designed to meet the demands of power-hungry PoE+++ (120W) and UPOE (90W) deployments, this cable ensures stable energy delivery in data centers, IoT hubs, and enterprise networks.

​​Technical Specifications and Design Advantages​​

• ​​16A Power Capacity​​: Supports up to 16 amps for high-density device stacks, including IP cameras, wireless APs, and AI-driven endpoints.
• ​​Robust Connectors​​: Features a C20 plug (equipment side) and C21 inlet (power source) for secure, low-resistance connections.
• ​​Enhanced Safety​​: Built with flame-retardant PVC and reinforced shielding to withstand 600V AC, compliant with ​​UL, IEC, and CE certifications​​.
• ​​Thermal Resilience​​: Rated for -40°C to 75°C operating temperatures, ideal for harsh environments.

​​Why Third-Party Cables Fall Short​​

Non-Cisco cables often lack the precision required for Catalyst 9000 switches, leading to:

• ​​Overheating Risks​​: Undersized conductors in generic cables can overheat under sustained 16A loads, damaging ports or triggering safety shutdowns.
• ​​Warranty Voidance​​: Cisco Technical Assistance Center (TAC) may refuse support if non-genuine accessories are detected.
• ​​Compliance Gaps​​: Failing to meet regional electrical codes (e.g., NEC in North America) could result in regulatory penalties.

​​From the Field: Why This Cable Isn’t Optional​​

After troubleshooting a Catalyst 9500 switch failure caused by a third-party cable, the lesson was clear: cutting corners on power infrastructure invites disaster. The CAB-9K16A-CH= isn’t just a component—it’s insurance against downtime. For enterprises scaling high-power IoT or AI deployments, this cable is as vital as the switch itself.
