1Introduction
Product Overview
The LAN35H08HR and LAN35E08HR are stackable 10-port unmanaged Gigabit Ethernet switches for expanding the networking capabilities of
any system. The boards can be used either in a PCIe/104 system or as a standalone stackable switch. In a stack the LAN35H08HR has a
host interface x1 PCI Express link for an onboard Gigabit Ethernet controller that is connected to one port of the switch. The LAN35E08HR
does not have an Ethernet controller and is designed to stack above an LAN35H08HR or another LAN35E08HR to provide additional switch
ports.
As standalone modules they each provide eight Ethernet ports any one of which can be the upstream port and the remaining will be
downstream ports. The LAN35H08HR has a power connector and the LAN35E08HR provides stackable expansion. This board is compatible
with all PCI Express cpuModules and has only the PCIe/104 connector. The boards are available in IDAN frames with two 37-pin “D”
connectors.
Board Features
•LAN35H08HR with host interface
oPCIe/104 PCI Express x1 link to onboard WG82574IT Gigabit Ethernet controller connects to one switch port
o8 ports brought to 10-pin DIL I/O connectors

oPower connector for standalone applications
•LAN35E08HR switch expansion
oPCIe/104 stack through connector for power only
o1 port for stack down expansion connector
▪Note: The stackdown connector is not PC/104 compliant, so exercise care if placing it above something other
than a LAN35H08HR or another LAN35E08HR. Standalone applications should use the LAN35H08HR.

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.
