2.6 PCIE-Q350 PCIe Bus Components
2.6.1 PCIe Bus Overview
The PCIE-Q350 has one PCIe x16 channel from the Intel® Q35 Northbridge and six PCIe
x1 lanes from the Intel® ICH9DO Southbridge. The PCIe bus lanes are interfaced to the
following devices.
One PCIe x16 lane is connected to one PCIe x16 graphics card on a
compatible backplane
Four PCIe x1 lanes are connected to four PCIe x1 expansion cards on a
compatible backplane
One PCIe x1 lanes are connected to two Intel® PCIe GbE connectors
One PCIe x1 is shared with the Intel® ICH9DO Gigabit LAN Connect
Interface (GLCI), which is connected to a Intel® 82566DM Gigabit platform
LAN connect device
2.6.2 PCIe x16 Expansion
The Intel® Q35 Northbridge chipset has one PCIe x16 port reserved for a PCIe x16
graphics card. The PCIe x16 lane is interfaced to a PCIe x16 slot on a compatible
backplane through two separate edge connectors on the bottom of the CPU card. The
PCIe x16 graphics card is then installed on the PCIe x16 slot on the backplane. The PCIe
x16 edge connector is shown in Figure 2-14.
