Introduction The ET91000SM20 converts a traditional copper Gigabit Ethernet connection (RJ45), into a Gigabit fiber connection. The media converter can then extend your network up to 20 km (12.4mi.) using single-mode LC fiber-optic cable. If needed, the included SFP module (LC fiber connector) can be removed from the media converter and be replaced with a transceiver module with different specifications.

Install the media converter The media converter features a pre-installed 1000Base-LX (transparent conversion) (1310 nm) Gigabit SFP transceiver module with LC connectors. This module transmits signals up to 20 km (12.4 mi.). Ensure the DIP switches are set appropriately to match your network infrastructure. Check with your network administrator, or your network documentation, as well as the DIP switch settings topic for details.
cause errors and signal degradation.
DIP switch settings The media converter features a four-position DIP switch that can be used to configure the ports for standalone operation.
Link fault pass-through (LFP) Link fault pass-through can notify you of link problems and provides an efficient solution for monitoring your network. The LFP DIP switch is set to OFF by default, and you can use the DIP switch to enable (ON) or disable (OFF) the LFP function. If you are familiar with your network infrastructure and proper diagnostic procedures, you can leave the LFP DIP switch in the OFF position. Otherwise, it is recommended to set the LFP DIP switch to the downward ON position.
Troubleshoot the Fiber link The media converter supports Gigabit fiber devices and cables only. It does not support 10/100Mbps fiber network devices or SFPs. • The fiber port supports an auto-negotiate (default) or FORCE (forced) mode setting. When connected to third-party equipment (for example, a Cisco switch) you might encounter fiber link problems. In this scenario, try setting the DIP switch positions to the FORCE (forced) mode setting, as well as the FULL (full duplex) setting.
