Appendix A. CRU instructions

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.
