Environmental Monitoring and Power Management
• It is in an n+n redundant mode, because n number of power supply modules are configured as active,
and the same number, as standby.
It also meets all the n+n redundant mode conditions:
• Although the setup and configuration in this example satisfy all the conditions, a full protected state is
not guaranteed.

• All power supply modules configured as active are of the same type; all modules configured as
standby are of the same type.
• A mix of AC-input and DC-input power supply modules are installed and all installed AC-input
power supply modules in the chassis are of the same capacity and have the same AC-input voltage
level.
In the sample output where
the AC-input modules also reflect that voltage is at 220 VAC.
• A mix of AC-input and DC-input power supply modules are installed, and all installed DC-input
power supply modules are configured as standby.
• Power supply modules of different capacities are installed, but the higher capacity modules are
configured as standby.
Note
When the system detects power supply modules of different capacities, the system
always considers and displays the operating state as normal protected.
