​​Understanding the CAB-C19-CBN= Power Cable​​

The ​​CAB-C19-CBN=​​ is a Cisco-certified, high-current AC power cable designed for enterprise-grade networking and data center equipment. Featuring a ​​C19 connector​​ (device end) and ​​C20 inlet​​ (power source), it delivers reliable power to high-wattage devices like chassis switches, blade servers, and UPS systems. The “CBN” identifier suggests compliance with ​​Canadian electrical standards​​, though its universal design supports global 200-250V grids when paired with region-specific PDUs.

​​Core Technical Specifications​​

• ​​Voltage/Current​​: Rated for ​​250V/16A​​, optimized for power-hungry Cisco hardware such as ​​Nexus 9500 switches​​ and ​​UCS B-Series blades​​.
• ​​Certifications​​: Meets ​​IEC 60320​​ for appliance couplers and ​​CSA C22.2​​ (Canada) or ​​UL 498​​ (US) for safety.
• ​​Length​​: 2-meter shielded design minimizes voltage drop in extended rack setups.
• ​​Durability​​: Flame-retardant PVC jacket resists abrasion and heat up to ​​105°C​​.

​​Primary Use Cases​​

• ​​Data Center Chassis​​: Supports redundant power supplies in high-density switches like the ​​Cisco Catalyst 9600 Series​​.
• ​​High-Performance Computing​​: Ensures stable power delivery to UCS servers running resource-intensive workloads.
• ​​Global Deployments​​: While compliant with North American standards, it adapts to international grids with certified PDUs.

​​Key User Questions Addressed​​

​​Q: Is this cable exclusive to Canadian deployments?​​
No. The “CBN” suffix denotes compatibility with North American safety standards, but it’s usable globally with proper PDUs.

​​Q: Can the CAB-C19-CBN= replace lower-rated C13/C14 cables?​​
Only for devices requiring C19/C20 connections. Using it for low-power devices like PoE switches is unnecessary and costly.

​​Q: What risks arise from using uncertified C19 cables?​​
Generic cables may lack proper shielding, leading to ​​arcing​​, overheating, or non-compliance with OSHA/NEC regulations.

​​Advantages Over Generic High-Current Cables​​

• ​​Precision Engineering​​: Cisco validates ​​±3% voltage tolerance​​ to prevent under/overvoltage shutdowns.
• ​​Safety Assurance​​: Dual-layer insulation and grounded shielding reduce electromagnetic interference (EMI) risks.
• ​​Warranty Protection​​: Non-Cisco cables may void warranties for connected devices like UCS or Nexus systems.

​​Lessons from High-Stakes Deployments​​

In a Toronto data center upgrade, a client’s use of uncertified C19 cables caused intermittent Nexus 9500 reboots during peak loads. Switching to CAB-C19-CBN= resolved the instability instantly. This cable isn’t just a conduit for electricity—it’s a safeguard against operational fragility. For teams managing critical infrastructure, its value lies in Cisco’s rigorous validation, turning potential failure points into pillars of reliability.
