Tier 1 customer replaceable unit (CRU): Replacement of Tier 1 CRUs is your responsibility. If IBM installs a Tier 1 CRU at your request, you will be charged for the installation.
Tier 2 customer replaceable unit: You may install a Tier 2 CRU yourself or request IBM to install it, at no additional charge, under the type of warranty service that is designated for your server.
Field replaceable unit (FRU): FRUs must be installed only by trained service technicians.

For information about the terms of the warranty and getting service and assistance, see the Warranty and Support Informationdocument.
