Extensive Fault Tolerance

The Cajun P550 switch is designed as a backbone switch. You can install the switch in your network’s core without creating a single point of failure.

Extensive fault tolerance features include:

❒N+1 power. Power supplies share the power supply load. If a power supply fails, the remaining supply or supplies assume the load automatically and the switch management system warns you of the failure.

❒Hot-swappable power supplies, fans, and modules - Each can be changed from the switch front panel, without powering down the switch.

❒Redundant switch links (using spanning tree and hunt groups).

❒Front-loadable cables, modules, power, supplies and fans.

❒Redundant switch matrix and switch controller modules.
