Cajun P550R/P880/P882 Installation Guide
Introduction
1-3
50-Series Mode The 50-series platform offers a switching fabric performance if 1.76
gigabit per second per fabric port. 50-series modules operate at
55MHz only. The presence of any 50-series modules within the
chassis will cause the chassis to operate in 50-series mode.
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 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

Fan Tray There are two fan assemblies in the chassis. One fan assembly is
located on the left side of the chassis to provide air flow to the media
modules installed. This fan assembly is hot-swappable. The other fan
assembly is located in the rear of the chassis to provide air flow to
the switch fabric. This fan assembly is not field replaceable.
Power Supplies Only two power supplies are required to support a fully-loaded
P550R chassis. A third power supply can be installed to provide
backup should one of the other two fail.
The power subsystem provides N+1 power supply redundancy. In
addition, the installed power supplies will load share between the
installed units. The power supplies are also warm swappable (power
supplies must be turned off and unplugged before removing them
from the chassis, however the other power supplies can remain on).

Fan Tray There are two fan assemblies in the chassis. One fan assembly is
located on the left side of the chassis to provide air flow to the media
modules installed. The other fan assembly is located in the rear of
the chassis to provide air flow to the switch fabric. Both fan
assemblies are hot-swappable and field replaceable.
Power Supplies Only two power supplies are required to support a fully-loaded
P880/P882 Chassis. A third power supply can be installed to provide
backup should one of the other two fail.
The power subsystem provides N+1 power supply redundancy. In
addition, the installed power supplies will load share between the
installed units. The power supplies are also warm swappable (power
supplies must be turned off and unplugged before removing them
from the chassis, however the other power supplies can remain on).
Switch Fabric
In 50-Series mode, the switching fabric provides a 16x16 crossbar
that provides 28.16 Gbps switching throughput (56.32 Gbps
aggregate bandwidth). In 80-Series mode, the switching fabric
provides a 31x31 crossbar that provides 69.696 Gbps switching
throughput (139.392 Gbps aggregate bandwidth).
The crossbar switch matrix provides low latency, high throughput
packet switching using a crossbar architecture.
Crossbars are inherently more scalable than shared memory
architectures. You can add more capacity simply by adding more
switch elements. By comparison, shared memory switches have an
inherent maximum upper boundary in throughput that makes
high-density, single-backplane gigabit switches impractical. This
means that as you increase the number of gigabit ports in your
network, the architecture can scale to meet your needs.
The P880/P882 chassis crossbar supports:
■31 fabric ports (two per I/O module slot, plus one for the
supervisor module).
■1.76 GB/s (in and out) on each fabric port in 50-series mode and
2.16 GB/s (in and out) on each fabric port in 80-series mode.
■28.16 GB/s total capacity, 56.32 GB/s total backplane capacity in
50-series mode and 56.32 GB/s total capacity, 139.392 GB/s
total backplane capacity in 80-series mode.

■Under-subscribed switching fabric in most configurations (two
connections per I/O module slot, plus one for the supervisor
module).
■Single copy replication - Input frames destined for output
multiple switch ports pass through the crossbar only once and
are copied by the crossbar to each destination.
■Hardware-assisted multicast pruning - The switch only forwards
to appropriate destination switch ports
50-Series Modules
The Cajun P550R/P880/P882 switches support the following
50-Series modules:
■Layer 2 Supervisor Module
■Layer 3 Supervisor Module
■Layer 2 and Layer 3 Fast Ethernet Modules
■Layer 2 and Layer 3 Gigabit-Speed Modules
■ATM Uplink Module
The layer 2 and layer 3 media modules implement wire speed
routing and bridging in Application-Specific Integrated Circuits
(ASICs). One set of ASICs supports a gigabit-per-second’s worth of
traffic (any combination of layer 2 and layer 3 modules). The
routing and bridging ASICs can process 1.5 million packets per
second, which is just slightly more than a gigabit’s worth of
minimum-sized Ethernet frames.
* Note: All layer 3 modules interoperate with the layer 2
modules and require the layer 3 supervisor module.
The layer 2 and layer 3 supervisor modules are both responsible for
learning addresses, and managing the address cache and the
Spanning Tree Protocol (STP).
The ATM Uplink module provides LAN Emulation (LANE)
connectivity over an ATM network.

Layer 2
Supervisor
Module
The layer 2 supervisor module provides the following features:
■Learns addresses
■Manages the address cache and the Spanning Tree Protocol
(STP)
■PowerPC 860 RISC processor
■Memory: 4 MB Flash, 8 MB DRAM, 128 KB NVRAM
■Multiple memory configurations (Table1-1):

Layer 3
Supervisor
Module
The layer 3 Supervisor module requires a faster CPU and more
memory. Also, unlike the layer 2 supervisor, the layer 3 supervisor is
part of the path that some packets take through the system. To
accomplish this, the layer 3 supervisor requires faster data transfer
to and from the switching fabric.
The layer 3 supervisor module features are:
■PowerPC 750 (RISC) processor
■Memory: 4 MB Flash, 64 MB DRAM, 128 KB NVRAM, 512 KB

Redundant Supervisor
The redundant supervisor module is an auxiliary (standby)
supervisor module that acts as a fault-tolerant supervisor in the
event that your active supervisor fails. The redundant supervisor
provides a seamless solution to switch failure. Once the redundant
supervisor is installed, loaded with the same software version as the
active supervisor, and synchronized, it is ready to act as a backup to
the active supervisor. If the active supervisor does fail, the
redundant module quickly assumes control with the least possible
affect on network operation. No user intervention is required for the
CPU module switchover. The management view is accessible
without changing IP or MAC addresses. The switch version (ver) is
logged and indicated via an SNMP trap.
* Note: If you installed a second supervisor module in slot 2 in
your switch, but do not require redundant supervisor
operation, you can remove the supervisor module from
slot 2 and restart your switch. There is no need to
upgrade the firmware if you are not running redundant
supervisors.
16 MB of memory is required on layer 2 supervisor
modules. If you have a P550R switch and the supervisor
module is not configured with 16 MB of memory, you
should order one of the following upgrades:
Model M5500-MEM16 for 16 MB upgrade
Or
Model M5500-MEM32 for 32 MB upgrade
Media Modules
All of the layer 3 media modules have the same general function as
the layer 3 supervisor module except for the following:
■The number and type of physical interfaces
■Hardware-based routing and bridging capacity
Bridging and routing are performed on the input side of each media
module. Frames whose destination Media Access Control (MAC)
address is on the same Virtual LAN (VLAN) as the interface on
which they arrived are bridged. Frames that are going from one
VLAN to another are routed. Some frames are both bridged and
routed, as is the case with multicast.

Cajun P550R/P880/P882 Installation Guide
Introduction
1-11
The media module’s features include:
■IEEE 802.3x full-duplex flow control - This allows the switch
ports to send a pause command before input buffers overflow.
Half-duplex ports support active backpressure (jamming).
■VLAN trunking or non-tagged access modes - This allows the
switch ports to interoperate with popular tagged trunking
schemes used by large networking vendors.
■Priority Queuing and Class of Service - These features
allow you to prioritize traffic between particular stations or
sets of stations to support jitter-sensitive applications.
Supported class of service (CoS) types include the
following:
—3COM PACE CoS
