Generation-correct supplies matched by machine type and FRU, with hot-swap units for paired bays.
System x3650 power supplies are specific to the machine generation: an M4 unit will not fit an M3, and so on through the family. Each generation shipped with several wattage options, commonly in the 460W to 900W range, with higher-wattage units on some machine types, and IBM sold the same physical supply under both an option number and a FRU number. The four-digit machine type on the front or rear label, not the marketing name, is what determines compatibility, since Lenovo continued the line after acquiring IBM's x86 business. Most configurations use paired hot-swap supplies, so replacement happens under power. Send us the machine type plus the FRU from the failed unit, or just the serial number, and we will match the correct replacement free of charge.
No. Each machine generation has its own supply family and they do not interchange. Match by the four-digit machine type first, then the FRU or option number.
They usually describe the same physical part through two numbering systems: option numbers for units sold as upgrades, FRU numbers for service replacements. Either one is enough for us to match your supply.
The four-digit machine type is printed on the chassis label next to the serial number, and the IMM reports it as well. Send the machine type and serial and we will match the correct supply free.
