Some rackmount systems ship fully assembled, with the SPS units and storage systems installed in a cabinet. Or you can plan to install an SPS yourself. If you will install the SPS in a rackmount cabinet, we assume that you have installed the SPS mounting tray (explained in the rails installation document shipped with the tray).

Some deskside units come with the SPS unit(s) already installed. You may want to add a second SPS to a deskside unit you already have.
