Chapter 6. Removing and replacing components
There are three types of replaceable components.
• Structural parts: Purchase and replacement of structural parts (components, such as chassis assembly,
top cover, and bezel) is your responsibility. If Lenovo acquires or installs a structural component at
your request, you will be charged for the service.
• 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.
See Chapter 5 "Parts listing, Lenovo System x3650 M4 HD Type 5460" on page 167 to determine whether a
component is a structural part, Tier 1 CRU, or Tier 2 CRU.
For information about the terms of the warranty, see the Warranty Information document that comes with
the server.
For more information about getting service and assistance, see Appendix D "Getting help and technical
assistance" on page 1135.
