5 Customer replaceable units
This chapter describes the procedures for replacing CRUs. Information about initial enclosure installation,
ESD protection, and common replacement procedures is also presented.
Customer self repair (CSR)
Table 27 identifies which hardware components are customer replaceable. Using WEBES, ISEE or other
diagnostic tools, a support specialist will work with you to diagnose and assess whether a replacement
component is required to address a system problem. The specialist will also help you determine whether
you can perform the replacement.
Parts only warranty service
Your HP Limited Warranty may include a parts only warranty service. Under the terms of parts only
warranty service, HP will provide replacement parts free of charge.
For parts only warranty service, CSR part replacement is mandatory. If you request HP to replace these
parts, you will be charged for the travel and labor costs of this service.
Best practices for replacing hardware components
The following information will help you replace the hardware components on your storage system
successfully. Follow these tips any time you must replace a component.
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 to install.
Verifying component failure
• Consult HP technical support to verify that the hardware component has failed and that you
are authorized to replace it yourself.
• Additional hardware failures can complicate component replacement. Check HP StorageWorks
Command View EVA and/or the WEBES System Event Analyzer as follows to detect any
additional hardware problems:
• When you have confirmed that a component replacement is required, you may want to clear
the Real Time Monitoring view. This makes it easier to identify additional hardware problems
that may occur while waiting for the replacement part.
• Before installing the replacement part, check the Real Time Monitoring view for any new
hardware problems. If additional hardware problems have occurred, contact HP support
before replacing the component.
• See the System Event Analyzer online help for additional information.
Procuring the spare part
Parts have a nine–character spare component number on their label ( Figure 30 ). The first six characters
(123479) identify the element; the last three characters (002) define the revision level. The replacement
