Office Enablement Kit components

There are three types of replaceable components: Tier 1 CRU, Tier 2 CRU, and FRU, based on who is responsible for installing the component.

  • Tier 1 customer replaceable unit (CRU). Replacement of Tier 1 CRUs is your responsibility. If IBM® installs a Tier 1 CRU at your request, you will be charged for the installation.
  • Tier 2 customer replaceable unit. You can install a Tier 2 CRU yourself or request IBM to install it, at no additional charge, under the type of warranty service that is designed for your computer.
  • Field replaceable unit (FRU). FRUs must be installed only by trained service technicians.

For information about the terms of the warranty, see IBM Statement of Limited Warranty Z125-4753-10 08/2008 and for information about getting service and assistance, see Getting help and technical assistance.
