The Avaya switch chassis comes in two models:
The P580 chassis.
The P882 chassis.
The P580 and P882 chassis can run in two modes:
Fabric Mode 1 = 55MHz or Fabric_mode 1
Fabric Mode 2 = 66Mhz or Fabric_mode 2
Fabric mode 1 has a switching fabric performance of 1.76 Gigabits per
second per fabric port. Fabric mode 1 modules operate at 55MHz only.
In Fabric mode 1 the P580 chassis will have a 13x13 crossbar switching
fabric, while the P882 chassis will have a 16x16 cross bar switching fabric.
In addition, the P882 chassis is limited to sixteen functional slots in this
mode (slot 17 can not be used).
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.
