Setting Network Circuit Redundancy
The redundancy application gives you the ability to deÞne redundant circuits for
your SEHI100TX to ensure that critical network connections remain operational.
Each circuit has a designated primary port and one or more backup ports. The
SEHI100TX monitors the link status of the primary portÕs connection to one or
more network IP addresses; if the link fails, the SEHI100TX automatically
switches trafÞc to a backup port.
To open the main Repeater Redundancy window:
from the icon:
1.
Click on the appropriate device 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 conÞgure redundancy, make sure that only the primary physical link is
connected to the network. If a backup port is connected before you conÞgure and enable
redundancy, you create a data loop.
