1Introduction
Product Overview1.1
The LAN17255HR is designed to provide five Gigabit Ethernet ports for expanding the networking capabilities of any system. The board can
be used either in a PC/104-Plus system or as a standalone module. In a stack it gets power from either the PCI bus, ISA bus, os a power
connector. It provides five RJ45 ports with auto-configuration so any of the ports can be upstream or downstream. This board is compatible
with all PC/104, PC/104-Plus, and PCI-104 cpuModules.
Board Features1.2
BroadCom BCM53115 Gigabit Ethernet Switch:
o5 Full Duplex Unmanaged Gigabit Ethernet Ports
Auto configuration means any of the ports can be an uplink or downlink
oIndustrial Temperature rated: -40 to +85 C
PC/104, PC/104-Plus, or PCI-104
oPCI and ISA Buses are used as a pass through interfaces on the LAN17255HR and only provide power to the module.

Board Handling Precautions3.1
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.

6. Check the stacking order; make sure all of the busses used by the peripheral cards are connected to the cpuModule.
7. Hold the module by its edges and orient it so the bus connector pins line up with the matching connector on the stack.
8. Gently and evenly press the module onto the PC/104 stack.
9. If any boards are to be stacked above this module, install them.
10. Attach any necessary cables to the PC/104 stack.
11. Re-connect the power cord and apply power to the stack.
12. Boot the system and verify that all of the hardware is working properly.

Block Diagram4.1
The Figure below shows the functional block diagram of the LAN17255HR. The various parts of the block diagram are discussed in the
following sections.
Figure 5: LAN17255HR Block Diagram
BroadCom Gig-Ethernet Switch4.2
The main component of the LAN17255HR is the BroadCom BCM53115 Gigabit Ethernet switch. This is an industrial temperature rated, 5 port
Gigabit Ethernet switch. This switch contains 5 full-duplex 10/100/1000 BASE-TX Ethernet transceivers for network interfacing. All 5 ports are
brought to RJ-45 connectors on the board. This allows the LAN17255HR to work as a switch in a stacked system. In a stand-alone system the
BroadCom switch acts as a basic Ethernet switch. Any port can be used as an upstream port to supply a connection to the 4 other ports.
Onboard LEDs and External LED Connectors4.3
The LAN17255HR has onboard LEDs for each of the five Ethernet ports on the board. The setting for the onboard LEDs is to show link activity,
link status and speed at 10/100/1000M. To bring the LEDs out of an enclosed system, there are 4-pin 0.1 inch DIL connectors for each port
that can be wired to external LED circuitry. These signals can source or sink 24 mA and the board has a jumper option for 3.3 volt or ground to
facilitate external LED configuration.

Module Handling Precautions5.1
To prevent damage due to Electrostatic Discharge (ESD), keep your module in its antistatic bag until you are ready to install it into your system.
When removing it from the bag, hold the module by the aluminum enclosure, and do not touch the components or connectors. Handle the
module in an antistatic environment, and use a grounded workbench for testing and handling of your hardware.
