The 80-series (also called series 2) platform is an evolution of the 50-series (also called series 1) architecture. It offers a 20% increase in switching fabric performance or 2.11 Gigabits per second per fabric port. This allows greater 10/100/1000 port density on a per crossbar port basis.
This increase in performance is accomplished with Avaya Application-Specific Integrated Circuits (ASICs) that operate at 66MHz (as well as 55MHz capable) and consolidates and enriches the functionality of a number of ASICs used in the 50-series modules.
If any 50-series modules are installed in the chassis, they do not turn on when the switch is in Fabric mode 2.
In Fabric mode 2, the P580 chassis will have a 13x13 crossbar switching fabric, while the P882 chassis will have a 33x33 cross bar switching fabric. All 17 slots in the P882 chassis can be used in Fabric 2 mode.
