With 80-Series modules, the P880/P882 chassis supports:
Up to 384 10/100BASE-TX ports (RJ-45 connector,
autosensing)
Up to 768 10/100BASE-TX ports (Telco connector,

Up to 384 100BASE-FX ports (MT-RJ connector)
Up to 128 gigabit-speed Ethernet ports
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. 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.
Only two power supplies are required to operate 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).
The P882 chassis supports both AC and DC power supplies. The
P880 chassis supports only AC power supplies.
In Fabric mode 1 (P880 and P882), the switching fabric provides a
16x16 crossbar with 56.32 Gbps aggregate bandwidth. In Fabric
mode 2 (P882 only), the switching fabric provides a 33x33 crossbar
with 139.392 Gbps aggregate bandwidth.
The crossbar switch matrix provides low latency, high throughput
packet switching using a crossbar architecture.
