Overview of the CAB-AC-2800W-TWLK= Power Cable

The ​​Cisco CAB-AC-2800W-TWLK=​​ is a ​​16A/250V AC power cable​​ designed for Cisco’s high-density Catalyst 9000 Series switches, including the C9400 and C9500 platforms. Engineered to deliver ​​2800W of power​​, this cable addresses the energy demands of modern data centers and enterprise networks. It complies with global safety standards while integrating seamlessly with Cisco’s power redundancy architectures, making it indispensable for environments prioritizing uptime and scalability.

Key attributes:

• ​​High-wattage support​​: Optimized for Cisco’s ​​2800W AC power supplies​​ in hyperscale deployments.
• ​​Global compatibility​​: Certified for use with IEC 60320 C19/C20 connectors, common in data center PDUs.
• ​​Durability​​: Industrial-grade shielding and heat-resistant insulation for 24/7 operations.

Technical Specifications and Safety

What power requirements does this cable address?

The CAB-AC-2800W-TWLK= operates at ​​200–250V AC with a 16A current rating​​, enabling it to power Cisco’s most demanding switches, such as the Catalyst 9500 with 100G uplinks.

Can it replace lower-wattage cables in existing setups?

Yes, but only if the connected devices and PDUs support 2800W power supplies. ​​Always verify PDU compatibility​​ to avoid circuit overloads.

How does it enhance safety in high-density racks?

The cable meets ​​UL 60950 and IEC 60950​​ standards, featuring flame-retardant materials and reinforced grounding to prevent electrical faults in high-heat environments.

Deployment Best Practices

• ​​Redundancy​​: Use with Cisco’s ​​N+N power supply configurations​​ to ensure zero downtime during grid instability or hardware failures.
• ​​Cable management​​: Avoid sharp bends within 10 cm of connectors to maintain shielding integrity.
• ​​Thermal monitoring​​: Pair with environmental sensors to detect overheating in densely packed racks.

Sourcing Authentic CAB-AC-2800W-TWLK= Cables

Counterfeit cables risk equipment damage and violate safety certifications. For verified Cisco hardware, “CAB-AC-2800W-TWLK=” is available here, ensuring compliance with global standards.

Key purchasing considerations:

• ​​Certification​​: Confirm UL and IEC markings on the cable jacket.
• ​​Scalability​​: Purchase spares for future expansions, especially in growing data centers.

The Cable That Powers Tomorrow’s Networks

Having managed data center migrations, I’ve seen firsthand how underpowered cables bottleneck performance. The CAB-AC-2800W-TWLK= isn’t just a component—it’s a ​​strategic asset​​ for enterprises scaling AI/ML workloads or 400G deployments. Cisco’s engineering ensures compatibility with smart PDUs and energy monitoring systems, which generic cables often fail to support. For teams betting on hyperscale infrastructure, this cable isn’t an option; it’s the foundation of ​​predictable, high-performance networking​​.
