Board Handling Precautions
To prevent damage due to Electrostatic Discharge (ESD), keep your board in its antistatic bag until you are ready to install it into your system.
When removing it from the bag, hold the board at the edges, and do not touch the components or connectors. Handle the board in an antistatic
environment, and use a grounded workbench for testing and handling of your hardware.

3.4.1 SWITCH SW1 –PCI SLOT SELECTOR
This rotary switch is used to set the positioning of the LAN17222 with respect to the CPU module and other PC/104-Plus or PCI/104 cards in
the stack.
Note: All PC/104-Plus and PCI/104 modules (including the LAN17222) must be on the same side of the CPU module.
If the LAN17222 is the first module from the CPU module, set the switch to position “0”. If it is the second module from the CPU, set the switch
to position “1”. Similarly, position “2” refers to the third module and position “3” refers to the fourth module away from the CPU module.
The PCI slot number can be configured as follows:

Block Diagram
The Figure below shows the functional block diagram of the LAN17222. The various parts of the block diagram are discussed in the following
sections.
Figure 8: LAN17222 Block Diagram
PCI to PCIe Bridge
The PCI to PCI-Express Bridge allows this Legacy PCI device to take advantage of PCI Express interfacing chips. It utilizes a single 33 MHz,
32-Bit PCI lane to create an x1 PCI Express link. This link is replicated and sent to the two Gigabit Ethernet controllers on the board.to PCI
Bridge allows legacy PCI devices to be used with newer PCI Express chipsets.
5.2.1 PCI EXPRESS HUB
The LAN17222 has an onboard PCI Express Signal Hub which allows it to provide a PCI Express link to each of the Ethernet controllers.
Intel WG82574IT Gigabit Ethernet Controller
The LAN17222 features two Gigabit Ethernet ports controlled by Intel’s WG82574IT Gigabit Ethernet controller. The WG82574IT is an
industrial temperature rated Gigabit Ethernet controller which features Auto-Crossover for MDI/MDI-X, 9KB Jumbo Frame Support, 40KB
packet buffer size and IPv4/6 support.
Link/Activity/Speed LEDs
Each Ethernet port has LED indicators which show link, activity and the speed of the connection.
Yellow LED: On indicates the link has been established. Blinks with activity
Blue LED: On indicates connection at 100 Mbps speed.
Green LED: On indicates connection at 1 Gbps speed.
