may or may not contain an IO9 PCI card and the devices and connector ports the
IO9 card supports.
Note: Each system requires one IO9 PCI card; this required card resides in the base
compute module. The system can contain additional IO9 cards that reside in the
expansion compute modules; these cards are required only when you want
additional SCSI hard disk drives, DVD-ROMs, and/or the connectors the IO9 card
supports.
For more information about the compute module (base compute module and system
expansion compute module), see "Compute Module" on page 83.
