The Symantec Storage Shelf contains two I/O modules, accessed from the rear panel
of the device. The SAS IN port is used to attach to a SAS RAID port on the rear
panel of the NetBackup 5220.
Connect SAS IN ports on each storage shelf I/O module to the equivalent SAS ports
in slot #5 of the PCI Riser Assembly in the rear of the NetBackup 5220.
One I/O module is shown below, however each storage shelf includes two such
modules.
