550W server power supply for X3550M5 and X3650M5

This 550W unit is built for Lenovo System x3550 M5 and x3650 M5 servers. It matches part numbers 94Y8138, 94Y8139 and 94Y8173. The supply is new and has been tested working. It serves administrators replacing a failed module or adding redundancy to a compatible chassis.

Thermals, noise and power draw in normal use

The unit delivers up to 550W of continuous power within the server's standard airflow path. Fan speed is managed by the system baseboard management controller, so acoustic output varies with inlet temperature and load. No independent thermal or noise figures are published for the supply alone.

Questions about this item

How do I install the 550W supply into an X3550M5 or X3650M5 and what step is often missed?

Slide the unit into the hot-swap bay until the latch clicks, then verify the amber LED turns green; the step most often missed is not pushing far enough to engage the latch.

What maintenance or replacement will the 550W supply need later?

Clean the intake vent every six months; replace the unit if the front LED stays amber or the server logs a power-supply fault.
