Depending on the model, your server might look slightly different from the illustration. Some parts are available only on some models.

The parts are identified as one of the following:
  • Tier 1 customer replaceable unit (CRU): Replacement of Tier 1 CRUs is your responsibility. If Lenovo installs a Tier 1 CRU at your request with no service agreement, you will be charged for the installation.

  • Tier 2 customer replaceable unit (CRU): 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.

  • Consumable and structural parts: Purchase and replacement of consumable and structural parts is your responsibility. If Lenovo acquires or installs a structural component at your request, you will be charged for the service.
