550W Hot-Swap PSU for ThinkServer RD350 RD450

This 550 watt hot-swap redundant power supply, model DPS550AB5 A and part number 00HV224, is a direct-fit replacement module built for ThinkServer RD350 and RD450 rack servers. It delivers stable continuous power to the motherboard, CPU, memory and hard disk backplane under long-term heavy-load operating conditions. Integrated overvoltage, overcurrent, overtemperature and short-circuit protections safeguard expensive server hardware from unexpected power damage.

Hotswappable Module Design for Zero-Downtime

The hotswap capability allows technicians to swap a faulty power module without shutting down the entire server system, maintaining service availability during maintenance. It matches the original chassis bay dimensions perfectly, so no modification is needed during installation. Each unit undergoes complete functional testing for voltage output, fan performance, load capacity and protection circuits prior to shipment to minimise DOA risk.

Redundant Power Limits in Small-to-Medium Data

This unit serves as a practical spare for enterprise server maintenance, redundant power configuration upgrades and defective original PSU replacement in small-and-medium data centre environments. Buyers who need higher total wattage or support for server models outside the RD350 and RD450 range cannot use this specific module. The 550 watt output defines the practical ceiling for the power budget this supply can sustain.
