Ssh-Telnet Console; Web Interface; Radius - ABB EDS500 Series Manual

Functions overview
For the critical level Alarm, a relais is switched that can control a signalization device. Unlike
spontaneous events that do not lead to an alteration of the operational state, alarms are
triggered by events that, while they prevail, modify the operational state.
The levels indicate the degree of limitation for operation that is caused by the event. For
some events, the administrator can set the alarm level, others are fixed.

SSH-Telnet console

Devices of the EDS500 series offer an SSH server and Telnet server to access a command
interpreter. Telnet is a network protocol to access the console of a remote device, SSH offers
additionally an encrypted connection. Both protocols are transported via TCP/IP.
The command interpreter of the EDS500 series translates user input into device settings.
There are different access levels. The view mode allows to view information and monitor
parameters. It is a read-only mode. The operation mode "configuration" has full access to the
system to modify the configuration and retrieve all system details.

Web interface

As an alternative to the command line oriented access method of the command interpreter
the web server of the EDS500 devices offers a comfortable user-interface. With an existing
IP connection to a device it can be configured and monitored fully using an ordinary web
browser.
3.3.11

RADIUS

RADIUS (Remote Authentication Dial-In User Service) is a network protocol to authenticate
logins. The RADIUS server runs as a central service e.g. in the central office. If you want to
connect to an arbitrary device, user name and password are sent to the RADIUS server that
in return tells the device if the login was successful. If so, access to the network device is
granted.
The EDS500 devices allow RADIUS authentication for the services Telnet, SSH, web server and
console.
