Chapter 6. Removing and installing FRUs

Replaceable components are of three types:
• Tier 1 customer replaceable unit (CRU): Replacement of Tier 1 CRUs is your responsibility. If Lenovo
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 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.
See Chapter 7 "Parts listing, ThinkServer RD220 Type 3729, 3779, 3797, and 3798" on page 205 to
determine whether a component is a Tier 1 CRU, Tier 2 CRU, or FRU.
For information about the terms of the warranty and getting service and assistance, see the Warranty and
Support Information document.
