This topic provides information about removing and replacing a customer replaceable unit or a field replaceable unit.

Note
The information and procedures in this documentation apply to both the 4-socket and the 8-socket configurations of the server, unless otherwise specified. Most of the illustrations in the documentation uses the 4-socket configuration of the server.

Replaceable components are of three types:

  • Tier 1 customer replaceable unit (CRU): Replacement of Tier 1 CRUs is your responsibility. If a Lenovo approved warranty service provider installs a Tier 1 CRU at your request, you will be charged for the installation.
  • Tier 2 customer replaceable unit (CRU): You may install a Tier 2 CRU yourself or request a Lenovo approved warranty service provider 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 Parts listing, System x3850 X6 and x3950 X6 Type 6241 to determine whether a component is a Tier 1 CRU, Tier 2 CRU, or FRU that must be replaced only by a trained service technician.

For information about the terms of the warranty, see the Lenovo Warranty Information document that comes with the server.
