Intel® Server Boards S3200SH/S3210SH TPS Functional Architecture
Revision 1.8 25
Intel Order Number: E14960-009
3.2.3.17 PCI Express* x4 Sub-system
The Intel
®
ICH9R supports one PCI Express* x4-lane interface that can also be configured as a
single x1 or x4-lane port. The PCI Express* interface allows direct connection with the PXH-V or
dedicated PCI Express* devices. (Fully compliant with the PCI Express* Base Specification,
Rev 1.0a).
3.2.3.18 PCI
One 32-bit PCI bus segment is directed through the Intel
®
ICH9R Interface defined as segment
A. This PCI Segment A supports two PCI connectors and one embedded Intel
®
82541PI LAN
controller.
The Intel
®
ICH9R does not contain a PATA device controller in the chipset; therefore, SATA
interface CD-ROM/DVD-ROMs are recommended for use with the server board.
3.2.3.19 SATA Controller
The Intel
®
ICH9R contains six SATA ports that support data transfer rates up to 300 Mbyte/s per
port.
3.2.3.20 Compatibility Modules (DMA Controller, Timer/Counters, Interrupt Controller)
The Intel
®
ICH9R provides the functionality of two-cascaded 82C59 with the capability to handle
15 interrupts. It also supports processor system bus interrupts.
3.2.3.21 Advanced Programmable Interrupt Controller (APIC)
The APICs in the Intel
®
ICH9R use messages on the FSB for interrupt generation and
notification to the processor.
3.2.3.22 Universal Serial Bus (USB) Controller
The Intel
®
ICH9R contains one EHCI USB 2.0 controller and can support four USB ports. The
USB controller moves data between main memory and up to four USB connectors. All ports
function identically and with the same bandwidth.
The server board provides two external USB ports on the rear panel of the server board. The
dual-stack USB connector is located within the standard ATX I/O panel area. The Universal
Serial Bus Specification, Revision 1.1 defines the external connectors.
The third/fourth USB port is optional and can be accessed by cabling from an internal 9-pin
connector located on the server board to an external USB port located either in front or the rear
of a chassis.
3.2.3.23 Enhanced Power Management
One of the embedded features of the Intel
®
ICH9R is a power management controller. It
implements ACPI-compliant power management features. The server board supports sleep
states S1, S4, and S5.
