Removing and replacing server components
This topic provides information about the four types of replaceable server
components.
Replaceable components are of four types:
v 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.
v 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.
v 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.
v Field replaceable unit (FRU): FRUs must be installed only by trained service
technicians.
