17 Replacing components in the X9720
Network Storage System
Customer replaceable components
WARNING!
Before performing any of the procedures in this chapter, read the important warnings, precautions,
and safety information in Appendix C and Appendix E.
IMPORTANT:
To avoid unintended consequences, HP recommends that you perform the procedures in this chapter
during scheduled maintenance times.
HP products are designed with many Customer Self Repair (CSR) components to minimize repair time
and allow for greater flexibility in performing defective parts replacement. If, during the diagnosis
period, HP (or HP service providers or partners) identifies that the repair can be accomplished by the
use of a CSR part, HP will ship that part directly to you for replacement. There are two categories of
CSR parts:
• Mandatory—Parts for which customer self repair is mandatory. If you request HP to replace these
parts, you will be charged for the travel and labor costs of this service.
• Optional—Parts for which customer self repair is optional. These parts are also designed for cus-
tomer self repair. If, however, you require that HP replace them for you, there could be additional
charges, depending on the type of warranty service designated for your product.
NOTE:
Some HP parts are not designed for customer self repair. To satisfy the customer warranty, HP requires
that an HP-authorized service provider replace the part.
CAUTION:
Be sure the replacement is available before removing a component or a blanking panel. Open slots
dramatically impact airflow and cooling within the device.
See Appendix A for diagrams of system components and cabling.
See Appendix B for a list of customer replaceable parts.
