Optional components, such as additional memory or PCIe cards that were ordered as part of the server, are installed in the server at the factory before the server is shipped. Any options not ordered with the server are shipped separately. If possible, install these components prior to installing the server in a rack.
Except for the rackmount kits, if you ordered any options that are not factory-installed, refer to the service manual for the server and the component's documentation for installation instructions.
