4.3 Serviceability
IBM Power Systems design considers both IBM and the client’s needs. The IBM Serviceability
Team has enhanced the base service capabilities and continues to implement a strategy that
incorporates best-of-breed service characteristics from diverse IBM Systems offerings.
The purpose of serviceability is to repair the system while attempting to minimize or eliminate
service cost (within budget objectives), while maintaining high customer satisfaction.
Serviceability includes system installation, MES (system upgrades or downgrades), and
system maintenance/repair. Depending upon the system and warranty contract, service may
be performed by the customer, an IBM representative, or an authorized warranty service
provider.
The serviceability features delivered in this system provide a highly efficient service
environment by incorporating the following attributes:
Design for customer setup (CSU), customer installed features (CIF), and
customer-replaceable units (CRU)
Error detection and fault isolation (ED/FI)
First-failure data capture (FFDC)
Converged service approach across multiple IBM server platforms
