Replaceable components are of three types:
- 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 blade server.
- Field replaceable unit (FRU): FRUs must be installed only
by trained service technicians.
See Parts listing, type 7891 to determine
whether a part is a tier 1 CRU, tier 2 CRU, or FRU component.
