1.4 Fiber optic Ethernet Interface
The EESX-Evaluation-Board provides SFP cages for optical Fast Ethernet (100Base-FX) SFP
transceivers for every Ethernet port. Even EESX30 module supports additionally 1000BASE-FX for GE-at
Ports # 1 and 2.
An optical DSC (1*9) transceiver is available at FE-Port 1 and can be implemented at costumer
’s design
for each FE-Port. (DSC transceiver at (Gigabit) GE-Ports are currently not supported by the software.)
Please contact the Hirschmann Service to order single DSC transceivers for your development. Find the
contact data of the service in the last chapter of this manual.

1.5 Mode-switch Settings for Ethernet Ports
Each Fast Ethernet port (FE) can operate in either 10/100Base-TX (using RJ45 connectors) or 100Base-
FX mode (using the SFP port) selected by the two Mode-switches (see Figure 1-7). The Gigabit Ethernet
ports (GE) can operate in either 1000Base-TX or 100/1000Base-FX mode.
To change between TX and FX mode both switchover contacts of each port must be put to TX or FX
position.

Note
: See chapter 3.4 for more information about setting the ports to TX or FX mode.
Note
: Port mode changes are activated after resetting the device.
