Chapter 4. Customer Replaceable Units (CRUs)
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.
The User Guide for your server provides instructions for replacing self-service and
optional-service CRUs. The User Guide is available on both the documentation
DVD that comes with your server and the Lenovo Web site at:
Note: Use only parts provided by Lenovo.
The following are lists of CRUs for machine types 70AL, 70AM, 70AN, and 70AQ.
