1 Introduction 1.1 Product Overview The LAN25255HR/LAN35255HR is designed to provide four Gigabit Ethernet ports for expanding the networking capabilities of any system. The board can be used either in a PCI/104-Express system or as a standalone module. In a stack it uses an x1 PCI Express link for an onboard Gigabit Ethernet controller. As a standalone module it provides four RJ45 ports one as an upstream port and 3 downstream ports. This board is compatible with all PCI Express cpuModules.
Figure 1: LAN25255 The Intelligent Data Acquisition Node (IDAN™) building block can be used in just about any combination with other IDAN building blocks to create a simple but rugged 104™ stack. This module can also be incorporated in a custom-built RTD HiDAN™ or HiDANplus High Reliability Intelligent Data Acquisition Node.

3 Board Connection 3.1 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. 3.2 Physical Characteristics Weight: Approximately 55 g (0.12 lbs.

3.4 Steps for Installing 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. Always work at an ESD protected workstation, and wear a grounded wrist-strap. Turn off power to the PC/104 system or stack. Select and install stand-offs to properly position the module on the stack. Remove the module from its anti-static bag. Check that pins of the bus connector are properly positioned. Check the stacking order; make sure all of the busses used by the peripheral cards are connected to the cpuModule.

4.2 BroadCom Gig-Ethernet Switch The main component of the LAN25255HR 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. One of these ports is used in conjunction with the WG82574IT for a host port. This allows the LAN25255HR to work as its own mini-server in a stacked system.
5 IDAN Connections 5.1 Module Handling Precautions 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. 5.2 Physical Characteristics Weight: Approximately 0.21 Kg (0.

6 Troubleshooting If you are having problems with your system, please try the following initial steps: Simplify the System – Remove modules one at a time from your system to see if there is a specific module that is causing a problem. Perform you troubleshooting with the least number of modules in the system possible. Swap Components – Try replacing parts in the system one at a time with similar parts to determine if a part is faulty or if a type of part is configured incorrectly.
