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.
