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. 28 ThinkServer RD340 User Guide and Hardware Maintenance Manual
