Chapter 5
Repeater Redundancy
This chapter describes how to configure and enable redundant circuits
Setting Network Circuit Redundancy
The redundancy application gives you the ability to define redundant circuits for
your EMM-E6 to ensure that critical network connections remain operational.
Each circuit has a designated primary port and one or more backup ports. The
EMM-E6 monitors the link status of the primary port’s connection to one or more
network IP addresses; if the link fails, the EMM-E6 automatically switches traffic
to a backup port.
To open the main Repeater Redundancy window
from the icon:
1. Click on the appropriate EMM-E6 icon to display the icon menu.
2. Drag down to Redundancy and release.
from the Hub View:
1. Click on to display the Device menu.
2. Drag down to Redundancy and release.
NOTE
Before you configure redundancy, make sure that only the primary physical link is
connected to the network. If a backup port is connected before you configure and enable
redundancy, you create a data loop.
