Parts Able to be Added/Replaced by Customers

The server provides parts that can be added/replaced under customer installation environment. The replaceable
parts are grouped into 2 types of FRU and CRU.
CRU is an abbreviation of Customer Replacement Unit. CRUs include components (modules/units/cables) that
can be replaced at failure occurrence or added by customers.
FRU is an abbreviation of Field Replacement Unit. FRUs include all components (modules/units) replaceable
when a failure occurs and are replaced by a maintenance service personnel.
The following shows the list of CRUs. There are 4 CRUs in the server (optical disk drive, hard disk drive, power
