CRU identification
CRUs are parts that can be upgraded or replaced by the customer. If a CRU is determined to be defective
during the warranty period, a replacement CRU will be provided to the customer. Customers are responsible
for installing the self-service CRUs for this product. Customers also can install optional-service CRUs, which
might require some technical skills or tools, or request that a technician install the optional-service CRU
under the terms of the applicable warranty service type for your country or region.
Non-CRUs must be replaced only by trained service technicians.
The following table lists the major FRUs in your server and the CRU identification information. For a complete
listing of FRU information, such as FRU part numbers and supported server models, go to:
