Two PCIe GbE connections through two Intel® controllers
Figure 2-19: PCIe Interfaces
2.8.1 PCIe x16 Expansion
The 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 golden fingers on the bottom of the CPU card. The PCIe x16 graphics card is
then installed on the PCIe x16 slot on the backplane.
2.8.2 PCIe x1 Expansion
The 3308290 has four PCIe x1 expansion channels interfaced to four PCIe x1
connectors on a backplane through a golden finger on the bottom of the CPU card. The
PCIe lanes are interfaced from the Intel® ICH8M-E Southbridge.
2.8.3 Intel® PC82573L PCIe Gigabit Ethernet (GbE) Controller
There is one Intel® PC82573L PCIe GbE controller installed on the 3308290. The Intel®
PC82573L is interfaced through a PCIe x1 channel to the Intel® ICH8M-E. The Intel®
PC82573L controller is then connected to an RJ-45 Ethernet connector enabling the
3308290 to be connected to an external network.
The Intel® PC82573L controller is a low power 10/100/1000 Mb/s PCIe GbE controller
that is ideal for non-managed platforms. Some of the Intel® PC82573L features are listed
below.
