Chapter 4. Hardware Upgrade and 
Replacement Procedures
The ClearCube architecture simplifies upgrading PC blades. All blade hardware and 
software components are classified as one of the following:
Customer Replaceable Units (CRUs)
Items that customers can replace.
Field-Replaceable Units (FRUs)
Items that trained service providers and ClearCube Systems Engineers (SEs) 
can replace, either on site or through an RMA process.
To maintain your ClearCube warranty and ensure proper operation, only use 
ClearCube approved commodities when performing upgrades of CRU components.
The following table details hardware and software components in R-series blades and 
indicates if each component is a CRU or an FRU.
