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 Parts listing, Lenovo System x3550 M4 Type 7914 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.
