Product Overview
The CP-860-DCHR-PSU= is a high-efficiency, dual-input DC power supply designed for Cisco Catalyst 9000 Series switches, including the Catalyst 9400 and 9600 chassis. This unit provides 3000W of power with N+N redundancy support, ensuring uninterrupted operation in mission-critical environments like data centers and industrial networks.
Core Technical Specifications
- Input Voltage: -48V to -60V DC (dual feed capable)
- Output Power: 3000W continuous (3kW peak)
- Efficiency: 94% typical under 50-75% load (80 Plus Platinum equivalent)
- Compatibility: Catalyst 9400/9600 Series (requires Supervisor Engine 1 or newer)
- Redundancy: Hot-swappable with support for 1+1 or 2+2 configurations
Key Deployment Scenarios
1. Data Center Core/Spine Layers
Ensures stable power for Catalyst 9600 switches handling 100GE traffic between server racks and storage arrays.
2. Industrial IoT Environments
Withstands harsh conditions (operating temperature -40°C to 70°C) for manufacturing plants using Cisco IE3400 switches in automation systems.
3. Telecommunications Edge Hubs
Supports 5G MEC (Multi-Access Edge Computing) deployments requiring dual DC feeds for carrier-grade uptime.
Addressing Critical User Questions
Q: Can this PSU replace older AC power supplies in Catalyst 9400 chassis?
A: No—the CP-860-DCHR-PSU= is DC-only. For AC compatibility, use the C9400-PWR-3KWAC model.
Q: How many units are needed for full redundancy?
A: Depends on total system draw. For a 9400 chassis with 4 slots:
- Base configuration: 2 PSUs (1+1)
- Full load (12kW): 4 PSUs (2+2)
Q: Does it support mixed voltage inputs?
A: Yes—each feed accepts -48V or -60V DC independently, simplifying integration with diverse power grids.
Purchasing and Installation Notes
For availability and chassis compatibility checks, visit the Cisco Catalyst 9000 power supplies page at itmall.sale. Ensure your DC circuit breakers are rated for 63A per feed to avoid tripping under peak loads.
Practical Perspective
While the CP-860-DCHR-PSU= excels in reliability, its DC-only design limits flexibility for organizations standardized on AC power. For telcos or industrial operators already invested in DC infrastructure, however, its 94% efficiency and dual-feed tolerance make it a future-proof choice—provided teams are trained to handle high-voltage DC safety protocols. The lack of auto-sensing input voltage could complicate deployments in regions with unstable power grids, but for controlled environments, it’s a workhorse.
