The Redundant Power Supply Unit asustor AS-250W-R for AS6504RD is a 250W replacement power module designed for use with the AS6504RD network-attached storage (NAS). It provides a hot-swap capable redundant power source that helps maintain continuous operation by replacing or complementing the primary power supply without shutting down the system. The unit is intended for environments where uptime and rapid on-site replacement are important, such as small office and home office NAS installations or server rooms that use fault-tolerant configurations.

Advantages

This redundant power unit delivers a stable 250W output and supports hot-swap replacement to minimize downtime during maintenance or component failure. It is designed for compatibility with the AS6504RD chassis, enabling straightforward installation and integration with the device's existing power management. The modular design simplifies on-site replacement and reduces service interruption risk by allowing the remaining power supply to continue operating while the unit is changed.

Suitable for

• AS6504RD NAS systems requiring a spare or secondary power module
• Server/NAS maintenance and field replacement tasks
• Fault-tolerant or high-availability small office and home office deployments
• Environments where hot-swap capability is needed to avoid shutdowns

Key specifications

• Output power: 250W
• Form factor: redundant/hot-swap power module compatible with specific NAS chassis
• Intended use: replacement or redundant supply for continuous operation
• Cooling: passively or actively cooled as per chassis design (uses system airflow)

How to use

To replace or install the Redundant Power Supply Unit asustor AS-250W-R, power down is typically not required if the NAS is configured for redundant operation; follow the NAS manufacturer’s hot-swap procedure for safe removal and insertion. Ensure the existing power module is identified and that the device indicates the unit is ready for removal. Insert the new module until it seats firmly and the retention latch engages. Verify system power indicators and management interface to confirm the new unit is recognized and functioning.

Usage recommendations

Use this unit as a matched spare for AS6504RD systems and keep a tested replacement on-site for rapid recovery. Follow the NAS manufacturer’s service manual for specific safety and hot-swap instructions, and ensure ambient temperature, ventilation, and power source meet the system specifications to maintain reliable operation.
