stations. All configurations are done at the Avaya Multiservice Switch, no
additional end station configurations are required. See
in Chapter 12, "Configuring IP
Ports within a Hunt Group by default are redundant to one another since
Hunt Groups perform load balancing among the ports. The Hunt Group
load-shares the traffic between two switches allowing the bandwidth to be
multiplied. The use of Hunt Groups also increases reliability since the links
behave as hot standby links to one another. If the traffic is shared over
multiple links, and one of the links is "lost", the traffic will be automatically
redistributed over the other links and the communications will continue
without interruption. See
Chapter 6, "Using VLANs, Hunt Groups, and VTP
details.
Only two power supplies are required to support a fully-loaded Avaya
Multiservice Switch. A third power supply can be installed to provide
backup should one of the other two fail. The power subsystem provides
N+1 power supply redundancy.
