Lantronix EDS16PS User Manual

The table below describes the LEDs on the back of the EDS.

The reset button is on the back of the EDS, to the left of the power connector. 
Pressing this button for 2-to-3 seconds reboots the EDS8/16/32PR and terminates all data activity 

occurring on the serial and Ethernet ports.

You can install the EDS8/16/32PR either in an EIA-standard 19-inch rack (1U tall) or as a desktop 

unit.   If using AC power, avoid outlets controlled by a wall switch.

1. Power off the serial devices that will be connected to the EDS8/16/32PR.
2. Attach a CAT 5 serial cable between the EDS8/16/32PR and your serial device. For a list of 

cables and adapters you can use with the EDS8/16/32PR, see Appendix C: Lantronix Cables 

and Adapters.

3. Connect an Ethernet cable between the EDS8/16/32PR Ethernet port and your Ethernet 

network.

4. Insert the power cord into the back of the EDS8/16/32PR. Plug the other end into an AC wall 

outlet. After power-up, the self-test begins.

5. Power up the serial devices.
