SKU CH-Q9AB-4VD0W

550W hot-swap redundant PSU replaces ThinkServer RD350 and RD450 units with pre-tested 80plus efficiency and wide AC input

  • 550W output powers RD350 and RD450 servers reliably
  • Hot-swap design allows module changes without system shutdown
  • 80 Plus efficiency reduces energy waste under continuous load
  • Pre-shipment testing verifies voltage, fan and protection circuits
  • Direct-fit form factor installs in original chassis bay unchanged

Direct Replacement for ThinkServer RD350 RD450

This 550W hotswap redundant server power supply, model DPS550AB5 A part number 00HV224, is engineered as a dedicated replacement for ThinkServer RD350 and RD450 rackmount servers. It matches the original chassis bay dimensions exactly, so no modification is required during installation. System administrators maintaining these specific platforms can swap the unit confidently, knowing the form factor and connectors align with the factory design.

Preshipment Testing Reduces Replacement Risk

Every unit undergoes comprehensive functional testing before shipment, verifying voltage output, fan rotation, protection circuits and overall working performance. This process helps ensure you receive a functional power module and lowers the chance of a defective unit complicating a repair. The testing covers the critical parameters that affect server uptime, giving maintenance teams greater assurance when deploying the spare.

Hotswap Design Supports Continuous Operation

The module supports hot‑swap insertion and removal, allowing replacement without powering down the entire server and preserving business continuity for critical workloads. Built‑in overvoltage, overcurrent, short‑circuit and overtemperature protections safeguard connected hardware during the swap. The 80plus high‑efficiency design accepts a wide AC input range, delivering stable power to the motherboard, CPU, memory and drive backplane under sustained heavy loads.

Questions about this item

When should the fan in the DPS550AB5 A be cleaned or replaced?

The unit uses a standard hotswap fan; clean the intake whenever dust builds up and replace the fan if bearing noise appears or airflow drops.

What protection trips first when the 550W PSU runs continuously at full load?

Overtemperature protection activates before the 550W limit if cooling cannot remove the heat fast enough.

How loud and hot does the 00HV224 get after 24 hours in a ThinkServer RD350?

The 80plus design keeps waste heat low; fan speed ramps with temperature so noise stays at normal server-room levels.
