PCI-Express* Subsystem

The PCI-Express* subsystem provides end-user support for nine PCI-Express* plug-in devices
in a 4U chassis. Seven of the plug-in devices are available for standard PCI-Express* adapters.
One device is for a custom I/O Riser, and the other is for a SAS Riser. The design enables easy
use and replacement of four PCI-Express* hot-plug devices without powering down the system.
