There are three types of replaceable components: Tier 1
CRU, Tier 2 CRU, and FRU, based on who is responsible for installing
the component.
-
Consumable part. Purchase and replacement of consumable
parts (components, such as batteries and printer cartridges, that
have depletable life) is your responsibility. If IBM acquires or installs
a consumable part 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 IBM® installs
a Tier 1 CRU at your request, you will be charged for the installation.
-
Tier 2 customer replaceable unit. You can install a Tier
2 CRU yourself or request IBM to install it, at no additional
charge, under the type of warranty service that is designed for your
computer.
-
Field replaceable unit (FRU). FRUs must be installed only
by trained service technicians.
