Cabling an Expansion Tray to a Controller Tray

A Controller tray has two expansion ports, one on the Controller A module and one on the Controller B module. To connect an expansion tray, connect an SAS cable from each expansion port on the controller to each In port on the expansion tray. FIGURE 2-18shows a 1x2 array configuration consisting of one controller tray and one expansion tray. Two SAS cables are required.
