WMtec 550W Server Power Supply

This WMtec server power supply delivers 550 watts across a 100-240V input range. It is built as a direct replacement unit for Lenovo RD350X RD450 RD450X RD550 RD650 and TD350 servers. The PS-2551-6L-LF 00HV185 model installs into the standard server bay without modification. System administrators can swap the module while the chassis remains powered.

Suits Lenovo RD and TD server fleets

This unit suits IT teams maintaining the listed Lenovo rack and tower models. It is not for builders assembling custom workstations or white-box servers that use standard ATX or redundant CRPS form factors. Buyers needing hot-swap redundancy should verify their chassis supports multiple modules. Anyone requiring a different wattage or connector layout must source an alternative part.

Questions about this item

How do I install the PS-2551-6L-LF 00HV185 into a Lenovo RD450 server, and what step is often missed?

Slide the unit into the hot-swap bay until the latch clicks, then verify the amber AC-OK LED turns green — many forget to confirm the LED change before closing the chassis.

What maintenance will the PS-2551-6L-LF 00HV185 need during its service life in a TD350?

Clean the intake mesh quarterly with low-pressure air; the internal fan is sealed and not user-serviceable, so replacement means swapping the entire 550 W module.
