Up to four IOUs can be mounted at the rear of the cabinet. Any combinations of IOU_1GbE, IOU_10GbE
installation are allowed. One and more IOU is required for each physical partition. PCI Express slot installed
in each IOU is allocated to partition.
To connect the IOU and the PCI_Box, a PCI_Box Connection Card in IOU (PCNC) must be installed at the
slot for connecting to the PCI_Box. PCNC can be installed at PCI express slot #2 or PCI Express slot #3 for
IOU_1GbE and can be installed at PCI express slot #2 for IOU_10GbE. The connector of the link card
bracket and the connector of the PCI_Box connection are then connected by a dedicated cable.
The overview of IOU_1GbE and IOU_10GbE are shown below.
