Hardware Architecture and Performance Benchmarks�...
Core Functionality and Technical Profile
The CAB-HVDC-3T-2M= is a 3-terminal, 2-meter high-voltage direct current (HVDC) power cable optimized for Cisco’s energy-efficient data center and enterprise power infrastructure. Designed to support 380V DC power distribution, it replaces traditional AC systems to reduce conversion losses. Key specifications include:
- Voltage rating: 380V DC (±10%)
- Current capacity: 20A per terminal
- Connector type: IEC 60309 3-pin industrial-grade plugs
- Safety compliance: UL 60950-1, IEC 62103, and NEBS Level 3 certified.
This cable integrates with Cisco’s HVDC power shelves (e.g., Nexus 93180YC-EX switches) to enable up to 99% PSU efficiency in hyperscale environments.
Strategic Use Cases and Efficiency Gains
Why migrate to HVDC with CAB-HVDC-3T-2M=?
- Energy savings: Eliminates AC/DC conversion layers, cutting power waste by 10-15% in high-density racks.
- Simplified cooling: Lower heat output versus AC systems reduces HVAC strain.
- Scalability: Daisy-chaining support for modular expansion in Cisco UCS blade deployments.
Ideal for Cisco Catalyst 9500-driven microgrids or edge compute nodes requiring stable, low-loss power over short distances.
Addressing Critical User Questions
1. Is CAB-HVDC-3T-2M= backward-compatible with AC-powered Cisco devices?
No—it requires HVDC-compatible PSUs like those in Cisco Nexus 9000 series switches. Retrofit kits are available for legacy upgrades.
2. What safety precautions apply during installation?
- Use insulated tools and PPE for 380V DC handling.
- Ensure proper grounding of power shelves to avoid arc flash risks.
- Avoid coiling excess cable to prevent electromagnetic interference.
3. Can multiple CAB-HVDC-3T-2M= cables be paralleled for higher current?
Yes, but balance loads across terminals to avoid uneven thermal stress. Cisco recommends a maximum of three parallel runs per PDU.
Sourcing and Authenticity Verification
HVDC systems demand precision engineering. Third-party cables lacking UL/IEC certifications risk equipment damage. For assured quality, procure CAB-HVDC-3T-2M= from authorized partners like itmall.sale, which provides Cisco-validated HVDC solutions.
Practical Insight: HVDC Isn’t Just for Hyperscalers
While HVDC adoption is often associated with mega data centers, its reliability and efficiency benefits extend to mid-sized enterprises. Having deployed CAB-HVDC-3T-2M= in hybrid cloud setups, I’ve observed a 12% reduction in monthly energy costs—without sacrificing uptime. The transition requires upfront planning, but for teams aiming to future-proof power infrastructure, this cable is a linchpin, not an option.
