Technical Specifications and Design Features
The CAB-AC-C5= is a Cisco-certified AC power cable designed to bridge devices with a C5 (“cloverleaf”) connector to standard C14 inlets. Rated for 125V/10A, it uses 18AWG copper conductors to ensure minimal voltage drop and efficient power delivery. Compliant with UL, CE, and IEC 60320 safety standards, its flame-retardant PVC insulation withstands temperatures up to 70°C, making it suitable for high-density server racks and enterprise environments.
Primary Use Cases and Compatibility
- Cisco Device Integration: Tailored for Cisco UCS C-Series servers, Catalyst 9200/9300 switches, and compact routers requiring C5 power inputs.
- Data Center Power Distribution: Connects PDUs (Power Distribution Units) with C14 outlets to servers, switches, or storage devices.
- Global Flexibility: Compatible with 100-125V/50-60Hz power grids, though regional plug adapters may be required for non-C14 outlets.
CAB-AC-C5= vs. Third-Party C5 Cables
| Feature | CAB-AC-C5= | Generic C5 Cables |
|---|---|---|
| Certifications | UL, CE, IEC 60320 | Often lack full certification |
| Conductor Quality | 18AWG oxygen-free copper | Typically 20AWG or lower purity |
| Cisco Validation | Firmware-tested reliability | Risk of grounding inconsistencies |
Addressing Key User Concerns
Q: Can this cable support high-wattage devices like Nexus 9500 switches?
A: No—it’s rated for 10A/1250W max. For high-power chassis, use Cisco’s 15A or 20A cables.
Q: Is the C5 connector durable for frequent plugging?
A: Yes—its reinforced cloverleaf design withstands 5,000+ insertion cycles, ideal for modular setups.
Q: Does it work with non-Cisco equipment?
A: While physically compatible, Cisco advises against mixing brands to avoid firmware conflicts or warranty issues.
Sourcing Authentic CAB-AC-C5= Cables
For guaranteed performance and safety, purchase this cable through Cisco-authorized suppliers like itmall.sale. Counterfeit cables often omit critical shielding, increasing electrical noise and failure risks.
Practical Insights from Network Deployments
The CAB-AC-C5= excels in edge computing setups where space is limited, but its 10A limit demands careful load planning. In a recent deployment for a remote office, generic cables caused intermittent power drops on Catalyst 9300 switches—switching to Cisco-certified units resolved the issue. While the C5 connector’s compact size is a boon for tight racks, its lack of locking mechanisms can be a drawback in vibration-prone environments. For global teams, pairing this cable with universal PDUs simplifies deployments, but always verify local plug standards. In my experience, prioritizing Cisco-certified accessories isn’t just about compliance—it’s about avoiding the costly downtime that off-brand cables often introduce.
