Cajun P550R/P880/P882 Switch User Guide
Introduction to the Cajun P550R/P880/P882 Switch
1-3
In 50-series operation the P550R chassis will have a 13x13 crossbar
switching fabric, while the P880/P882 chassis will have a 16x16
cross bar switching fabric. In addition, the P880/P882 chassis is
limited to sixteen functional slots in 50-series mode (slot 17 can not
be used).
80-Series Mode The 80-series platform is an evolution of the 50-series architecture.
It offers 20% increase in switching fabric performance or 2.11
gigabit per second per fabric port. This allows larger 10/100/1000
port density on a per crossbar port basis.
This increase in performance is accomplished with new Cajun ASICs
that operate at 66MHz (as well as 55MHz capable) and consolidate
as well as enrich the functionality of a number of ASICs currently
used in the 50-series modules.
This increased performance can only occur if the entire switch
contains 80-series modules. The presence of any 50-series modules
within the chassis will cause the chassis to operate in 50-series
mode.
In 80-series operation the P550R chassis will have a 13x13 crossbar
switching fabric, while the P880/P882 chassis will have a 31x31
cross bar switching fabric.
P550R Chassis
The Cajun P550R Chassis consists of:
■ Seven slots (1 slot for the supervisor module and six payload
slots for media modules)
■ Fan Tray
■ Increased port density
■ Up to three power supplies
■ A 13x13 crossbar switch fabric
Slots The P550R chassis consists of seven slots. Slot 1 is dedicated for a
supervisor module and the remaining six of which are payload slots.
If a redundant supervisor is used in the chassis, it must be inserted
into slot 2 of the chassis.
Ports The P550R chassis configured with 50-series modules provides
support for:
