About this Manual
The “Redundancy Configuration” user manual contains all the information
you need to select a suitable redundancy procedure and configure it.
The “Basic Configuration” user manual contains all the information you need
to start operating the device. It takes you step by step from the first startup
operation through to the basic settings for operation in your environment.
The “Installation” user manual contains a device description, safety instruc-
tions, a description of the display, and all the other information that you need
to install the device before you begin with the configuration of the device.
The “Industry Protocols” user manual describes how the device is connected
by means of a communication protocol commonly used in the industry, such
as EtherNet/IP and PROFINET.
The "Web-based Interface" reference manual contains detailed information
on using the Web interface to operate the individual functions of the device.
The "Command Line Interface" reference manual contains detailed informa-
tion on using the Command Line Interface to operate the individual functions
of the device.
The Network Management Software HiVision provides you with additional
options for smooth configuration and monitoring:
XEvent logbook.
XConfiguration of „System Location“ and „System Name“.
XConfiguration of the network address range and SNMP parameters.
XSaving the configuration on the device.
XSimultaneous configuration of multiple devices.
XConfiguration of the port display color red for a connection error.

1 Introduction
The device contains a range of redundancy functions:
XHIPER-Ring
XRedundant coupling of HIPER-Rings and network segments
XRapid Spanning Tree Algorithm (RSTP)
Three tools are available for operating these functions:
XWeb-based Management (supplied with the Switch)
for convenient agent configuration (see Reference Manual -
Web-based Interface).
XCommand Line Interface (supplied with the Switch)
for setting elementary functions (see reference manual – Command Line
Interface).
XHiVision Network Management
for convenient cross-agent configuration
(see manual – HiVision Hirschmann Network Management).
