Configuration Using Telnet
To access and configure the device server by using a Telnet session over the network, you must 
first establish a Telnet connection. You can also establish a Telnet connection by clicking the 
Telnet Configuration tab in DeviceInstaller. See the DeviceInstaller Online Help for more 
information, available on our website www.lantronix.com/support/downloads
.
To access the EDS1100/2100 by using Telnet, perform the following steps.
1. Click Start > Run. The Run dialog box displays.
2. Type telnet x.x.x.x (x.x.x.x is the IP address). The EDS1100/2100 is online when the 
command prompt (>) displays.  You are at the root level of the CLI.
Note: Depending on the level of security, a password may be required. 
Configuration Using Serial Ports
Serial Command Mode
The serial port can be configured to operate in command mode permanently or to be triggered 
under specified conditions. See the line <line> Level command description for more information.
Serial Recovery
In this mode, the normal boot process is interrupted, allowing recovery from unknown or incorrect 
configuration settings. While the back door is active, the CLI prompt is changed to “>>” (instead of 
“>”) and the Web Manager is inaccessible. These serve as an important indication that the device 
boot processes has been temporarily halted. To complete the boot process, terminate the serial 
CLI session (with the exit command).
