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:

The I/O expansion functionality is physically partitioned into four rack mounted chassis-the I/O
expansion utilities chassis (XUC), the I/O expansion rear display module (RDM), the I/O expansion
power chassis (XPC) and the I/O chassis enclosure (ICE). Each ICE supports up to two 12-slot I/O
chassis.

When an I/O Expansion cabinet is ordered as an upgrade to a Superdome system, it includes the factory
testing and integration of any components that are ordered at the same time as the cabinet. This
includes any I/O Chassis, PCI or PCI-X cards and peripherals. If it is ordered as an upgrade but not at
the time of the Superdome system, additional installation assistance may be required and can be
ordered as field installation products.

The only field rackable I/O expansion components are the ICE and the 12 slot I/O chassis. Either
component would be field installed when the customer has ordered additional I/O capability for a
previously installed I/O expansion cabinet.
No I/O expansion cabinet components will be delivered to be field installed in a customer's existing rack
other than a previously installed I/O expansion cabinet. The I/O expansion components were not
designed to be installed in racks other than the 10K G2 Universal Rack. In other words, they are not
designed for Rosebowl I, pre merger Compaq, Rittal, or other third party racks.
The I/O expansion cabinet is based on the 10K G2 Universal Rack and all expansion components
mount in the rack. Each component is designed to install independently in the rack. The 10K G2
Universal Rack has been modified to allow I/O interface cables to route between the ICE and cell
boards in the Superdome cabinet. I/O expansion components are not designed for installation behind a
rack front door. The components are designed for use with the 10K G2 Universal Rack perforated rear
door.
