Overview
Chassis
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
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.
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).

Fabric Mode 2
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.

All 17 slots in the P882 chassis can be used in Fabric 2 mode.
