2.6 Internal I/O subsystem
The internal I/O subsystem resides on the system planar which supports a mixture of both
PCIe and PCI-X slots. All PCIe or PCI-X slots are hot pluggable and Enhanced Error
Handling (EEH) enabled. In the unlikely event of a problem, EEH-enabled adapters respond
to a special data packet generated from the affected PCIe or PCI-X slot hardware by calling
system firmware, which will examine the affected bus, allow the device driver to reset it, and
continue without a system reboot.
