install it, at no additional charge, under the type of warranty service that is designated for your compute
node.
• Field replaceable unit (FRU): FRUs must be installed only by trained service technicians.
• Consumable and Structural parts: Purchase and replacement of consumable and structural parts
(components, such as a cover or bezel) is your responsibility. If Lenovo acquires or installs a structural
