DULG Manual for PPC440EP (yosemite)
Field Replaceable Unit
FRU(Field Replaceable Unit) 現場可更換單元。
廠商為了節省成本，把設備分成多個FRU，大到power supply,小到fan之類的。直接更換而不修，所以大家以後想更換零件先看看它是不是fru。如果設備上沒有表示fru，那麼有part number（或者product number，serial number） 的就是FRU。
PART NUBMER 是廠商給用戶看的，如果你想買某個部件，那PARTS就是跟價格相關的。 PRODUCT NUMBER 是給廠商自己看的，同一個部件（PARTS）可能有多個product number.廠商給你供貨、保修時是看這個的。
SERIAL NUMBER，配合PART NUMBER 廠商可以確認設備的真假，合同，保修情況等。
