7 Removing and replacing hardware components
This chapter describes procedures for removing and replacing hardware components.
Customer self repair
HP customer self repair (CSR) programs allow you to repair your StorageWorks product. If a CSR
part needs replacing, HP ships the part directly to you so that you can install it at your convenience.
Some parts do not qualify for CSR. Your HP-authorized service provider determines whether a
repair can be accomplished by CSR.
For more information about CSR, contact your local service provider, or see the CSR website:

Best practices for replacing components
The following sections provide information to help you successfully replace the hardware components
on your messaging system.
WARNING! To reduce the risk of personal injury or damage to the equipment:
• Be sure that only one component is extended from a rack at a time. A rack may become
unstable if more than one component is extended at the same time.
• Do not extend the hard drive drawers beyond the supporting surface when the unit is not
installed in a rack.
CAUTION: Removing a component significantly changes the air flow within the enclosure. All
components must be installed for the enclosure to cool properly. If a component fails, leave it in
place in the enclosure until a new component is available for installation.
During replacement of the failed component
• HP recommends waiting until periods of low messaging system activity to replace a component.
• When replacing components at the rear of the rack, cabling may obstruct access to the
component. Carefully move any cables out of the way to avoid loosening any connections.
In particular, avoid cable damage that may be caused by:
◦ Kinking or bending
◦ Disconnecting cables without capping. If uncapped, cable performance may be impaired
by contact with dust, metal, or other surfaces.
◦ Placing removed cables on the floor or other surfaces where they may be walked on or
otherwise compressed.
Accessing component replacement videos
HP produced videos of the procedures to assist you in replacing components. To view the videos,

Identifying the spare part
Parts have a nine-character spare part number on their label. For some spare parts, the part number
is available in the messaging system. Alternatively, the HP call center can assist in identifying the
correct spare part number.
