CRU identification
Customer Replaceable Units (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 Field Replacement Units (FRUs) in your storage array and the CRU
identification information. For a complete listing of FRU information, such as FRU part numbers and
