​​Understanding the CAB-AC-2800W-6-20= Power Cord​​

The ​​CAB-AC-2800W-6-20=​​ is a Cisco AC power cable designed for high-power networking equipment. This 2800-watt-rated cord features a NEMA 6-20P plug, optimized for 200–240V power inputs. It’s engineered to support Cisco devices requiring robust power delivery, such as chassis switches or modular routers.

​​Key Technical Specifications​​

• ​​Power Rating​​: 2800W at 200–240V AC
• ​​Plug Type​​: NEMA 6-20P (commonly used in North America for 240V circuits)
• ​​Compatibility​​: Tailored for Cisco Catalyst 9400 Series switches and other high-demand systems.
• ​​Safety Standards​​: UL-listed and CE-certified for electrical safety.

​​Common Use Cases and Deployment Scenarios​​

This power cord is critical in environments where ​​high power redundancy​​ is non-negotiable:

• Data centers deploying Cisco Catalyst 9400 switches in stacked configurations.
• Enterprise networks requiring dual power supplies for failover setups.
• Industrial setups with 240V power infrastructure.

​​User Concerns Addressed​​

​​Is the CAB-AC-2800W-6-20= backward-compatible with older Cisco hardware?​​

No. The cord’s 6-20P plug and 2800W capacity align with newer high-power Cisco systems. Older devices with lower wattage requirements (e.g., Catalyst 3850) use standard 120V cables.

​​Can third-party alternatives replace this cord?​​

While generic 6-20P cables exist, Cisco’s ​​2800W-rated design​​ ensures precise thermal management and compliance with device firmware power checks. Non-Cisco cables may trigger system alerts or void warranties.

​​How does this differ from CAB-AC-2800W-6-15= models?​​

The ​​6-20P plug​​ (20A/240V) supports higher current than the 6-15P (15A/240V). Mismatching plugs can lead to connector damage or power instability.

​​Final Thoughts​​

In high-stakes networking environments, using manufacturer-certified power components like the CAB-AC-2800W-6-20= isn’t just a recommendation—it’s a safeguard against downtime and hardware failures. Cutting corners with uncertified cables risks both performance and compliance, a tradeoff rarely worth the marginal cost savings.
