Peripheral Support
All peripherals qualified for use with Superdome and/or for use in an RBII-D rack are supported in the IOX
cabinet as long as there is available space. Peripherals not connected to or associated with the Superdome
system to which the IOX is attached may be installed in the IOX.
No servers except those required for Superdome system management such as test stations or High
Availability Observatories may be installed in an IOX.
Peripherals installed in the IOX cannot be powered by the XPC. Provisions for peripheral AC power must be
provided by a PDU or other means.
I/O Card and Cable Configuration Limits
The maximum number of I/O cards supported in a Superdome system is defined in the Superdome
Installation Guide. There is distinction between cards located in the CPU cabinet and those in the IOX. The
absolute worst case number of I/O cables that can result in an IOX is untenable from a cable management
perspective. The design limits for maximum cards and their resulting cables in an IOX are defined in
Table 1-8.
