Chapter 4. Removing and replacing blade server components
Use this information to remove and replace components of the JS12 Type 7998
blade server that are replaceable.
Replaceable components are of three types:
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 blade server.

Field replaceable unit (FRU): FRUs must be installed only by trained service
technicians.
See Chapter 3, “Parts listing, Type 7998,” on page 235 to determine whether a part
is a Tier 1 CRU, Tier 2 CRU, or FRU component.
