The core I/O in Superdome provides the base set of I/O functions required by every Superdome
partition. Each partition must have at least one core I/O card in order to boot. sx2000 systems must
have I/O cards with at least LAN connectivity as its "core" I/O capability in each partition. Multiple core
I/O cards may be present within a partition (one core I/O card is supported per I/O backplane);
however, only one may be active at a time. Core I/O will utilize the standard long card PCI X form factor
but will add a second card cage connection to the I/O backplane for additional non PCI X signals (USB
and utilities). This secondary connector will not impede the ability to support standard PCI X cards in the
core slot when a core I/O card is not installed.
Any I/O chassis can support a Core I/O card that is required for each independent partition. A system
configured with 16 cells, each with its own I/O chassis and core I/O card could support up to 16
independent partitions. Note that cells can be configured without I/O chassis attached, but I/O chassis
cannot be configured in the system unless attached to a cell.
The core I/O card's primary functions are:
Partitions (console support) including USB and RS-232 connections
10/100Base-T LAN (general purpose)
Other common functions, such as Ultra/Ultra2 SCSI, Fibre Channel, and Gigabit Ethernet, are not
included on the core I/O card. These functions are, of course, supported as normal PCI-X add-in cards.
The unified 100Base-T Core LAN driver code searches to verify whether there is a cable connection on an
RJ-45 port or on an AUI port. If no cable connection is found on the RJ-45 port, there is a busy wait
pause of 150 ms when checking for an AUI connection. By installing the loopback connector (description
below) in the RJ-45 port, the driver would think an RJ-45 cable was connected and would not continue to
search for an AUI connection, hence eliminate the 150 ms busy wait state

For Windows Server 2003 and Windows Server 2008, Windows does not support the 10/100 LAN on
the A6865A core I/O card, a separate Gigabit Ethernet card such as the A7061A, A7073A, A9899A,
or A9900A is required. The use of Graphics/USB card (A6869A/A6869B) is optional and not required.
NOTE: A6869A is not supported on systems with the sx2000 chipset.
