No one knows stacking like Avaya. We
introduced our first Stackable Chassis
product in 1998 and have been
perfecting the technology ever since.
We were the first and only vendor to
break the Terabit boundary with our
ERS 5600 Series products and we have
differentiated ourselves in the industry
by ensuring that our Stackable Chassis
perform like a traditional modular
chassis implementation. We offer
genuine chassis-like features including
true pay-as-you-grow scaling and in
service maintenance and restoration.
From a management perspective, our
Stackable Chassis looks like a single
network entity – utilizing only a single
IP address.
A stack of up to eight 24-port Avaya
ERS 3500 units can be created,
enabling the Ethernet Routing Switch
3500 series to deliver up to 80Gbps
stacking throughput by scaling up
to 192 x 10/100 ports and 16 x
10/100/1000/ SFP combo ports, or
192 x 10/100/1000 ports. Note that
stacking support will be delivered in
software version 5.1 for the ERS 3526T /
ERS 3526T-PWR+ and ERS 3524GT /
3524GT-PWR+ models.

Our Stackable Chassis products
combine non-blocking internal
switching fabrics with a high-speed
virtual backplane architecture to
deliver a high performance solution
that scales proportionally as new
switches are added. The ERS 3500
series scales to a maximum of
80Gbps of virtual backplane
throughput by simply cabling up 8
units together. Avaya’s Stackable
Chassis architecture simplifies stack
management. Customers do not
have to worry about different
software versions on different
products, since all ERS 3500 units
run the same software image. The
software image is loaded onto the
base unit of the stack which then
loads the image to all the other
switches in the stack. As new units
are added to the stack, the ERS 3500
automates the software image and
configuration download process.
Third party testing

has validated that
new ERS 3500 units can become
operational in just over 2 minutes of
being cabled into the stack.
To ensure wire-speed performance,
our Stackable Chassis architecture is
based on a shortest-path forwarding
algorithm for optimal data flow
across the stack. Unlike competitive
solutions that use unwieldy logical
ring or token technology, Avaya
allows traffic to flow upstream and
downstream simultaneously from
every switch connected to the virtual
backplane, optimizing performance,
resiliency, and resource utilization.
Avaya has an additional advantage in
that Quality-of-Service settings are
honored as traffic passes over the
stacking connections – providing
applications with optimal
performance, and a positive user
experience.
All ERS 3500 models come with two
in-built Stackable Chassis interfaces
for simple, cost-effective and
efficient connectivity. Unlike
comparative offerings which daisy
chain low-speed interfaces, this
design frees uplink ports for
dedicated connectivity to the
backbone. In addition to the stacking
cables, a return cable is also used to
provide full virtual chassis resiliency
and to protect against any stack
port, switch unit or cable failures.
