Up to 120 10/100BASE-TX ports (RJ-45 connector,
autosensing)
Up to 288 10/100BASE-TX ports (Telco connector,
autosensing)
Up to 60 100BASE-FX ports
Up to 24 gigabit-speed Ethernet ports
With 80-Series modules, the P550R chassis provides support for:
Up to 144 10/100BASE-TX ports (RJ-45 connector,
autosensing)
Up to 288 10/100BASE-TX ports (Telco connector,
autosensing)
Up to 144 100BASE-FX ports (MJRT connector)
Up to 48 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 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.
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).
In 50-Series mode, the switching fabric provides 22.88 Gbps
switching throughput (45.76 Gbps aggregate bandwidth). In 80-
Series mode, the switching fabric provides 27.455 Gbps switching
throughput (54.91 Gbps aggregate bandwidth).
The crossbar switch matrix provides low latency, high throughput
packet switching using a crossbar architecture (Figure 1-1).
