7.1
Overview of the IOU
This section provides an overview of IOUs and describes their mounting locations.
Each IOU consists of one I/O board (IOB), eight PCI slots, and up to four hard disk drives
(HDD). A PCI card or link card is mounted in a PCI slot by using a PCI cassette. For slots in
which no PCI card or link card is mounted, a filler panel may occupy the slot. When an IOU
is replaced, these mounted components (PCI cassettes, PCI cards, HDDs, and other
components) must be remounted. These mounted parts must be remounted at the same
locations in the new IOU as their original pre-swap mounting locations.
