Standard system components are installed at the factory. Optional components that you purchased independently of the standard configuration are shipped separately, and in most cases can be installed before you install the server in a rack.
You can order and purchase the following optional components separately:
DDR4 DIMM memory kits
If you ordered field-replaceable units (FRUs) or customer-replaceable units (CRUs), refer to the service label on the top cover of the server, or the component removal and installation procedures in the Oracle Server X8-2 Service Manual or Oracle Server X8-2L Service Manual.
Supported components and their part numbers are subject to change over time and without notice. For the most up-to-date list, review the Oracle System Handbook, which is available from the My Oracle Support website.
To access the handbook, log in to My Oracle Support at https://support.oracle.com, click the Knowledge tab, and in the knowledge links, click Oracle System Handbook. In the handbook, click Current Systems, and then click the name and model of your server. On the product page that opens for the server, click Full Components List for a list of components.
