the server.
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 (CRU): 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.

technicians.
