Page 4: Introduction
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. -

Page 6: Install The Media Converter
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. -

Page 9: Link Fault Pass-Through (Lfp)
The RJ45 port supports Gigabit (1000Base-T) network devices and cables only. It does not support 10/100Mbps copper (RJ45) network devices. The ET91000SM20 is a transparent media converter (it is not a switch). Therefore, the duplex setting of your fiber network equipment must match that of the media converter’s RJ45 copper UTP port. -
Page 10: Troubleshoot The Fiber Link
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. -
