Replaceable server components
Replaceable components are of three types:
• Self-service customer replaceable unit (CRU): Replacement of self-service CRUs is your responsibility.
If Lenovo installs a self-service CRU at your request, you will be charged for the installation.
• Optional-service customer replaceable unit: You may install an optional-service CRU yourself or
request Lenovo to install it, at no additional charge, under the type of warranty service that is designated
for your server.
• Field replaceable unit (FRU): FRUs must be installed only by trained service technicians.
For information about the terms of the warranty and getting service and assistance, see the Warranty and
Support Information document.
The following table lists the part numbers for the server components.
