FRU 43y6493 confirms exact part match for service

The field replaceable unit number 43y6493 is the single specification that guarantees this card matches the original hardware qualification for the supported ThinkPad series. Verifying this FRU against your service manual ensures the adapter will be recognised by the system BIOS and whitelist. Without this match the card may not function even if the M.2 keying appears correct.
