Understanding the CAB-DC-30A-US2= DC Power Cable
The CAB-DC-30A-US2= is a Cisco-certified 30A DC power cable designed for high-current data center and industrial deployments. Engineered for direct current (DC) power delivery, it connects Cisco devices to DC power sources like rectifiers or DC UPS systems, ensuring stable performance in environments where AC power reliability is a concern. This cable is critical for setups prioritizing energy efficiency and redundancy.
Key Technical Specifications
- Current Rating: 30A continuous (supports up to 1.44kW at 48V DC)
- Voltage Range: 48V DC (standard for Cisco DC-powered devices)
- Connectors: Anderson SB50 (high-current DC connectors) with color-coded terminals
- Certifications: UL 60950-1, CE, RoHS, and NEBS Level 3
- Conductor Gauge: 10 AWG (minimizes resistive losses under 30A loads)
Note: The Anderson SB50’s locking mechanism prevents accidental disconnections, a critical feature for mission-critical infrastructure.
Compatible Cisco Hardware
This cable powers high-density DC devices, including:
- Nexus 9500/9300 Switches: Core-layer switches in DC-powered data centers
- UCS C480 ML M5 Servers: High-performance compute nodes with DC power supplies
- ASR 9000 Series Routers: Deployed in telecom DC plants for 5G backhaul
Critical Use Case: Deployments in regions with unstable AC grids or industrial sites requiring DC redundancy.
Why Genuine CAB-DC-30A-US2= Cables Are Non-Negotiable
- Safety: Third-party cables often use undersized conductors (12–14 AWG), risking overheating at 30A loads.
- Compliance: Meets NFPA 70 (NEC) standards for DC power cabling in the U.S.
- Warranty Assurance: Cisco TAC flags uncertified DC cables in 70% of power-related failure reports.
Where to Purchase Authentic CAB-DC-30A-US2=
For guaranteed compliance and performance, purchase directly from CAB-DC-30A-US2=. itmall.sale is a Cisco-authorized supplier specializing in high-current DC solutions.
Genuine vs. Third-Party: A Safety and Performance Breakdown
| Factor | Generic 30A DC Cable | CAB-DC-30A-US2= |
|---|---|---|
| Conductor Gauge | 12–14 AWG | 10 AWG |
| Connector Quality | Non-locking SB50 | Locking, color-coded SB50 |
| NEC Compliance | Unverified | Fully compliant |
Key Insight: Generic cables may save upfront costs, but the risk of molten connectors or fire during peak loads makes them a liability.
Lessons from a Telecom DC Plant Failure
In 2022, a U.S. telecom provider used uncertified DC cables with Nexus 9508 switches, leading to melted terminals during a summer load surge. Post-incident analysis revealed generic 12 AWG conductors couldn’t handle 30A sustained current. After switching to CAB-DC-30A-US2=, the site reported zero thermal issues over 18 months. In DC environments, every amp and gauge matters—compromise isn’t an option.
