Connecting four storage shelves to an appliance
Note:
The cables in the following diagrams are shown in different colors for demonstration purposes only. The actual cables are black.
Note:
The orientation of the blue tabs on the ends of the SAS-3 cables is important.
In the appliance, the blue tabs on each SAS-3 connector must face down.
In the storage shelves, the blue tabs in the SAS-3 connectors should point to the 12 Gb/s SAS label near each port. The blue tabs on the SAS-3 connectors inserted into the top row must face down. The blue tabs of the connectors inserted into the bottom row must face up.
To connect four storage shelves to an appliance
- Connect a SAS-3 cable to the left port in the appliance RAID PCIe card.
- Connect the other end of the SAS-3 cable to port A in the top I/O module of the first storage shelf.
- Connect SAS-3 cables between the remaining four storage shelves.
- Connect a SAS-3 connector to port A in the bottom of the I/O module in the fourth shelf.
- Connect the other end of the cable to the right port in the appliance RAID PCIe card.
- Connect a SAS-3 cable to port B in the bottom I/O module of the fourth shelf. Connect the other end of the cable to port A in the bottom I/O module of the third shelf.
- Connect port B in the bottom I/O module of the third shelf to port A in the bottom I/O module in the second shelf.
- Connect port B in the bottom I/O module of the second shelf to port A in the bottom I/O module in the first shelf.
Next, connect network and power cables. Turn on the storage shelves and the appliance per the required sequence. Verify that all units function correctly.
