Parts list

Use the parts list to identify each of the components that are available for your compute node.

For more information about ordering the parts shown in Figure 1:

Note

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

Graphic showing all parts associated with the compute node

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 compute node.
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.
