detailed overview of the port traffic. The counters give a comprehensive overview
in the areas of:

Stackable Architecture
A CrossFire 8730 switch can be stacked together with other CrossFire 8730
switches and with switches from the CrossFire 8600 series in any desired
combination to provide uplinks like ATM, HSTR, and Fast Ethernet. For more
information on stacking, refer to the CrossFire 8600 Series documentation.
Optional Redundant Power Supply
The switch has an input for a backup power supply. It is compatible with the
CrossFire 8310 Redundant Power Supply Chassis, which can supply backup power
for up to six switches, when up to six CrossFire 8311 Redundant Power Supply
Units are installed in the chassis. This gives a high degree of resilience to power
supply failures. The switch will start using the external power supply if the internal
supply fails. The switch monitors the power source and informs the network
management system which supply is in use.
The CrossFire 8300 Switch Stacker also accommodates an optional switch matrix
8301, which includes a redundant power supply, ensuring the highest degree of
resilience in the stack of switches.
Caution: The redundant power supply unit CrossFire 8311 is not hot-swappable.
Both the CrossFire 8311 unit and the switch must be off before connecting or
disconnecting the DC power cable.
