CP-840-DCHR-PS-AU=: How Does It Optimize Power Delivery for Cisco 840 Series Chassis?

​​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.
