CN1 and CN2, plug the External MiniSAS HD to External MiniSAS HD cables (CBL-
SAST-0573) into the JBOD out downstream port of the JBOD where the 1st backplane
is located and into the JBOD in upstream port of the JBOD where the 2nd backplane is
located, as illustrated in Figure C-5.
4. A 3rd backplane can be added using a connection from CN3 and CN4 of the 2nd
backplane through its JBOD out downstream port.
5. Close the chassis cover, plug the power cords into the rear of the power supplies, and
power up the system.
