Use this information to remove and replace the server components.
The types of replaceable components are:

cover, and bezel) is your responsibility. If Lenovo acquires or installs a structural component at your
request, you will be charged for the service.
• Tier 1 customer replaceable unit (CRU): Replacement of Tier 1 CRUs is your responsibility. If Lenovo
installs a Tier 1 CRU at your request, you will be charged for the installation.
• Tier 2 customer replaceable unit (CRU): You may install a Tier 2 CRU yourself or request Lenovo to
install it, at no additional charge, under the type of warranty service that is designated for your server.
