Depending on the model, your server might look slightly different from the illustration.

Figure 1. Server components

The parts listed in the following table 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 (components, such as a cover or bezel) is your responsibility. If Lenovo acquires or installs a structural component at your request, you will be charged for the service.
