Cisco N540-PWR400-A= 400W AC Power Supply Unit for Network Convergence System 540

The Cisco N540-PWR400-A= is a high-performance 400W AC power supply unit specifically engineered for the Cisco Network Convergence System 540 router series. This module provides a reliable and stable power source, essential for maintaining the continuous operation of critical network infrastructure in enterprise environments. Designed with hot-plug and redundancy capabilities, it allows for seamless maintenance and replacement without interrupting network services.

Advantages

This power supply unit offers significant operational benefits by supporting a wide input voltage range, which ensures compatibility with various power grid standards. Its hot-plug design facilitates rapid replacement, minimizing downtime during hardware maintenance or unexpected power module failures. By providing redundant power, it enhances the overall availability and reliability of the network system, protecting against single points of failure in power delivery.

Suitable for

• Enterprise-grade network convergence systems
• Data centers requiring high availability
• Critical infrastructure networking environments
• Cisco Network Convergence System 540 series routers

When it may not be suitable

This power supply is exclusively designed for the Cisco Network Convergence System 540 series and is not compatible with other router models or networking hardware. It is not intended for use in non-standard electrical environments that fall outside the specified input voltage range.

Key specifications

• Power output: 400 Watts
• Input voltage range: 90-265V AC
• Form factor: Hot-plug module
• Compatibility: Cisco Network Convergence System 540 series
• Functionality: Redundant power support

How to use

To install the power supply, ensure the router is powered on if the system supports hot-swapping. Slide the unit into the designated power supply bay on the rear of the Cisco NCS 540 chassis until it is securely seated and the locking mechanism engages. Connect the appropriate AC power cable to the input port on the module. The system will automatically detect the new power source and begin distributing power to the router components.

What to consider before purchase

• Verify compatibility with your specific Cisco NCS 540 model
• Ensure your rack power distribution unit supports the required AC input
• Check if your current configuration requires redundant power modules

Usage recommendations

For optimal system stability, it is recommended to install redundant power supplies in separate power circuits to ensure continuous operation even during a localized power failure. Always use genuine Cisco power cables to ensure safe and reliable electrical connectivity.
