1 Overview
1.1 Introduction
The EXP-ETH8 is an Add-on Module conforming to the EPIC ExpressTM Specification.
It comprises eight independent 10/100/1000 Mb/s ports that can be easily connected to RJ45 sockets mounted
at the front of the module.
The state of link, speed and activity is show by two LEDs on every socket.
The EXP-ETH8 supports Stack-up and Stack-down to a CPU Module.
Furthermore the EXP-ETH8 uses the 5 Volt and 3.3 Volt power supplied from the PCI/104-Express connector.
All other voltages are generated on the board itself.
The EXP-ETH8 runs with Linux and Windows operation systems.

3.4 PCI/104 Express Bus Interface
The EXP-ETH8 uses x16 link of the PCI/104-Express bus. Which link is used depends if the board is stacked-up
or stacked -down.
On the module there is a PCI Express switch that detects the type of connection and forwards the other links
according to the specification.
The EXP-ETH8 can be used with the Hurricane-QM57.
At the Hurricane-QM57 you can stack-up one EXP-ETH8. Theoretical could be connected two EXP-ETH8, but
then they are limited to 4 Ethernet Ports at each add-on. The reason for this is the limitation of the I/O space
(and also therefore the devices) in the PCI-to-PCI bridge specification.
