Redundant function
This server enables a redundant configuration for fan, power supply unit (optional), and Management
Blade.
The Management Blade supports the standard redundant configuration in which one unit manages the
entire system in the master mode and another one is on standby in the slave mode. In this configuration,
if the master Management Blade causes a failure, the slave blade takes over management without
interrupting system operations.
