Overview of the CAB-AC-30A-US4= Power Cable
The Cisco CAB-AC-30A-US4= is a 30A/250V AC power cable designed for high-density Cisco Catalyst switches, UCS servers, and data center equipment. Built to meet NEMA L6-30P standards, this cable supports demanding power requirements in environments like hyperscale data centers or industrial networks. Unlike generic alternatives, it ensures precise compatibility with Cisco’s high-current power supplies, minimizing risks of voltage drops or connector failures under load.
Key features:
- High-current capacity: Delivers up to 30A for Cisco’s 6kW–10kW AC power systems.
- Regional compliance: Certified for US NEMA L6-30P outlets, common in commercial and industrial settings.
- Robust construction: Heavy-duty insulation and shielded connectors rated for continuous 60°C operation.
Technical Specifications and Safety Standards
What devices require this cable?
The CAB-AC-30A-US4= is essential for powering Cisco’s Catalyst 9500H Series switches and UCS C4800 ML servers, which demand 30A input for high-performance workloads like AI/ML or real-time analytics.
Can it be used with non-Cisco PDUs or racks?
While physically compatible with standard NEMA L6-30R receptacles, Cisco strongly advises against mixing with third-party PDUs due to potential mismatches in power tolerances and surge protection.
How does it enhance safety in high-load scenarios?
The cable meets UL 60950 and NEC Article 400 standards, featuring double-layered insulation and strain relief collars to prevent arcing or insulation cracks during thermal expansion.
Deployment Best Practices
- Circuit validation: Ensure upstream breakers and PDUs are rated for 30A continuous load to avoid tripping.
- Redundancy: Pair with Cisco’s dual 30A power supplies for N+1 redundancy in mission-critical setups.
- Thermal management: Allow adequate spacing between cables in conduit to dissipate heat generated by 30A current flow.
Sourcing Authentic CAB-AC-30A-US4= Cables
Counterfeit cables risk catastrophic failures, including melted connectors or fire hazards. For guaranteed compliance, “CAB-AC-30A-US4=” is available here, offering Cisco-certified hardware with full warranty coverage.
Critical purchasing considerations:
- Certification proof: Verify UL and NEMA markings on the cable jacket.
- Future scalability: Stock spares for rapid replacements, as lead times for custom 30A cables can delay projects.
The Uncompromising Role of High-Current Cables
In data center retrofits, I’ve encountered melted third-party cables that crippled operations for days. The CAB-AC-30A-US4= isn’t just a component—it’s a liability mitigator for enterprises pushing power infrastructures to their limits. Cisco’s rigorous testing ensures seamless integration with intelligent PDUs and power monitoring tools, which generic cables often lack. For teams deploying high-density AI clusters or high-frequency trading systems, this cable isn’t optional—it’s the backbone of predictable, high-uptime performance.
