Defining the CP-840-DCHR-PS-AU=
The CP-840-DCHR-PS-AU= is a Dual-Chassis Hot-Rod AC Power Supply designed for Cisco’s 840 Series integrated routers, specifically the Cisco 840 ISR (Integrated Services Router). This module provides redundant, high-efficiency power for environments demanding uninterrupted connectivity, such as branch offices or small-to-midsize enterprise networks.
Core Technical Features
- Power Output: 600W AC input (100–240V) with active-active redundancy.
- Compatibility: Tailored for Cisco 840 Series routers (e.g., ISR 845, ISR 857).
- Redundancy: Dual power feeds ensure failover during outages, critical for always-on applications like VoIP or SD-WAN.
- Certifications: Meets 80 PLUS Gold efficiency and complies with AU/NZ electrical safety standards.
- Hot-Swappable: Replace or upgrade without interrupting router operations.
Key Benefits for Network Stability
1. Seamless Power Redundancy
The dual-chassis design eliminates single points of failure. If one power supply fails, the second instantly takes over, minimizing downtime risks for latency-sensitive services.
2. Energy Efficiency
By achieving 90%+ efficiency under typical loads, this module reduces operational costs and heat generation—a critical advantage in compact installations with limited cooling.
3. Regional Compliance
The “AU” designation ensures adherence to Australia/New Zealand voltage and safety regulations, avoiding compatibility issues with local power grids.
Addressing Common Deployment Questions
Q: Can this power supply support third-party modules in the 840 chassis?
Yes, but only if those modules are Cisco-validated. Non-certified hardware may overload the system or void warranties.
Q: How does it differ from the CP-840-S-PS-AU=?
The CP-840-DCHR-PS-AU= offers dual-chassis redundancy, whereas the CP-840-S-PS-AU= is a single power supply without failover capabilities.
Where to Source Reliable Units
For guaranteed performance and compliance, purchase the CP-840-DCHR-PS-AU= through itmall.sale’s Cisco catalog. Unauthorized sellers may supply refurbished or non-compliant units, risking router integrity.
Practical Takeaway
The CP-840-DCHR-PS-AU= isn’t just a power supply—it’s a strategic safeguard for businesses reliant on Cisco 840 Series routers for edge networking. Its dual-chassis design and regional certifications make it ideal for Australian/New Zealand deployments, but its value hinges on proper integration. Avoid pairing it with non-Cisco hardware, and prioritize genuine components to maintain both efficiency and support entitlements. For organizations scaling distributed networks, this module is a non-negotiable investment in operational resilience.
