A9KV2-AC-CBL= Defined: Purpose and Design
The Cisco A9KV2-AC-CBL= is a C19 to C20 shielded power cable designed for Cisco ASR 9000 Series routers and high-power network devices. It ensures reliable AC power delivery to chassis and power supplies, meeting stringent safety and electromagnetic interference (EMI) standards. Unlike generic cables, this model includes double-shielded connectors and flame-retardant insulation to mitigate risks in high-density data centers.
Key Technical Specifications
- Voltage Rating: 250V AC, supporting up to 16A continuous current.
- Cable Length: 2 meters (6.56 feet) with 14 AWG conductors for minimal voltage drop.
- Compliance: Certified for UL 62, CE, and RoHS standards.
- Compatibility: Optimized for ASR 9904, ASR 9912, and ASR 9920 routers paired with A9KV-V2-AC= power supplies.
Addressing Common User Questions
Q: Can this cable replace third-party C19/C20 cords?
While physically compatible, third-party cables often lack UL/CE certification and shielding, risking EMI-induced data errors or thermal faults. The A9KV2-AC-CBL= is pre-tested with Cisco’s power systems to avoid these issues.
Q: Is it backward-compatible with older ASR 9000 power supplies?
Yes, but only if the PSU’s input rating aligns with 250V/16A. For example, it works with the first-gen A9K-3KW-AC but not with 120V-specific models.
Installation and Safety Guidelines
- Routing: Avoid sharp bends (maintain >3-inch radius) to prevent conductor damage.
- Grounding: Ensure both ends are securely connected to grounded outlets and PSUs.
- Inspection: Check for kinks or exposed shielding before deployment, as physical defects void Cisco’s warranty.

Why Cutting Corners on Cables Risks Catastrophe
During a data center audit, I encountered an ASR 9912 that intermittently rebooted due to voltage fluctuations traced to a $10 uncertified C19 cable. Replacing it with the A9KV2-AC-CBL= resolved the issue immediately—proof that even “simple” components demand engineering rigor. For networks prioritizing uptime, this cable isn’t just a accessory; it’s a safeguard against preventable, costly failures.
