Configuring Redundancy Options
Configuring Redundant Hardware
The Avaya Multiservice switches provide a redundant backplane to ensure
that should a Supervisor module, Switch Controller, or fabric element fail, it
will continue to forward data properly. The redundant components are
available as separate options.
Redundant Switch Controllers and Elements
Controllers and Elements are located at the rear of the switches. When the
redundant controller and element are installed, the backplane consists of the
following parts (
Figure 10-1 or Figure 10-2 ):
■
One Primary Controller
■
One Redundant Controller
■
Six Active elements
■
One Redundant element
