User Replacement Guideline
The Hitachi Compute Rack system is designed with many customer replaceable
units (CRUs) to allow for greater flexibility in performing defective parts
replacement. However, customer should consult with Hitachi Data Systems
Support about the failed parts before replacement. After consultation, Hitachi
Data Systems Support will ship the spare part directly to you for replacement.
The system unit contains several LEDs that light when certain problems occur,
making it easy for users to quickly find the source of these problems.
The LEDs are described in this chapter.
User maintenance tasks
The maintenance tasks described in this manual follow the Hitachi Data Systems
Customer Support program.
The Hitachi Data Systems self-service program allows users to perform
allowable installation and configuration tasks and maintenance tasks on the
