CAB-9K16A-US1=: What Makes It the Go-To Power Cable for Cisco Catalyst 9000 in the US Market?

​​Defining the CAB-9K16A-US1= Power Cable​​

The ​​CAB-9K16A-US1=​​ is a Cisco-certified 16A alternating current (AC) power cable engineered for Catalyst 9000 Series switches, including the Catalyst 9300, 9400, and 9500. As per Cisco.com, this cable adheres to U.S. electrical standards, specifically UL and NEMA certifications, making it indispensable for deployments requiring compliance with North American safety regulations.

​​Core Technical Specifications​​

• ​​Voltage Range​​: 100–240 VAC, 50/60 Hz, ensuring compatibility with U.S. commercial power grids.
• ​​Connectors​​: C19 (device end) to NEMA 6-20P (wall plug), optimized for high-power outlets.
• ​​Certifications​​: UL 60320, NEMA 6-20P, and Cisco’s internal validation for Catalyst 9000 hardware.
• ​​Durability​​: 3-meter length with flame-retardant insulation, rated for 0–60°C operation.

​​Why the CAB-9K16A-US1= Is Non-Negotiable​​

​​1. Regulatory Compliance​​
Using uncertified cables can violate U.S. electrical codes and void Cisco’s hardware warranties. The CAB-9K16A-US1= meets ​​UL and NEMA benchmarks​​, mitigating risks like fire hazards or non-compliance penalties.

​​2. High-Power Demands​​
Catalyst 9000 switches often drive Power over Ethernet Plus+ (PoE++) configurations, requiring stable 16A input. Generic cables may fail under sustained loads, causing voltage drops or port shutdowns.

​​Addressing Key User Concerns​​

​​Q: Can I reuse older Cisco power cables with Catalyst 9000 switches?​​
A: Only if they’re C19/C20 type and rated for 16A. Cisco.com explicitly warns against using lower-amperage cables (e.g., 10A CAB-AC10A) for PoE++ use cases.

​​Q: Does the cable support three-phase power systems?​​
A: No. The CAB-9K16A-US1= is designed for single-phase AC systems, per Cisco.com’s documentation.

​​Q: How critical is ambient temperature?​​
A: Prolonged exposure above 60°C may degrade insulation. Ensure proper airflow in densely packed racks.

​​Sourcing the CAB-9K16A-US1=​​

​​Final Perspective​​

In U.S. network deployments, cutting corners on power infrastructure is a recipe for downtime. The CAB-9K16A-US1= isn’t just a cable—it’s a compliance anchor and a reliability multiplier. For enterprises running Catalyst 9000 switches, investing in certified power accessories isn’t optional; it’s a baseline for risk mitigation and operational integrity.
