Cabling the Expansion Enclosure to a Storage System Connect an SC180 expansion enclosure to the back-end SAS ports on an SCv2080 storage controller. NOTE: In an SC180 expansion enclosure, the left storage controller is storage controller 1 and the right storage controller is storage controller 2. 1. Connect a SAS cable from storage controller 1: port A to the expansion enclosure: left EMM, port C. 2. Connect a SAS cable from storage controller 2: port B to the expansion enclosure: left EMM, port B. 3.
Figure 5. Power Cables 3. Secure each power cable to the expansion enclosure chassis using the strain relief fasteners. 4. Plug the other end of the power cables into a grounded electrical outlet or a separate power source such as an uninterrupted power supply (UPS) or a power distribution unit (PDU). CAUTION: Be careful when closing the rear rack door to ensure that power cords have adequate space as some racks might not be sufficiently deep.
