LAN35H08HR & LAN35E08HR User’s Manual
Intel WG82574IT Gigabit Ethernet Controller
The LAN35H08HR has an onboard Gigabit Ethernet controller, the Intel WG82574IT. The Intel WG82574IT is an industrial rated Gigabit
Ethernet controller which features Auto-Crossover for MDI/MDI-X, 9014 bytes Jumbo Frame support, 40KB packet buffer size and IPv4/6
support. This controller connects to the host CPU through a x1 PCI Express link on the PCIe/104 connector and interfaces through the fifth port
of the Ethernet switch to provide a host port for stacked systems.
Onboard LEDs and External LED Connectors
The LAN35H08HR has onboard tri-color LEDs for each of the ten Ethernet ports on the board. The setting for the onboard LEDs is to show
link, activity, and speed at 10/100/1000M. There are two 0.1 inch DIL connectors (CN7 & CN8) that can be wired to external LED circuitry.
They carry a link/activity signal for each port.
