IOU (IO unit)
This section describes the IOU of the PRIMEQUEST 2000 series.
The IOU is a component shared by all the models. There are two types of IOUs, namely, IOU_1GbE and
IOU_10GbE depending on the type of available PCI Express cards and bandwidth.
2.8.1 IOU (IOU_1GbE/IOU_10GbE) specifications
The specification of the IOU is listed in the table below.

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
