Environmental Monitoring and Power Management
Example: n+1 Redundant Mode (Power Supply Modules of the Same Capacity but Different Types + Normal Protected State
PS1 (Active)
C9400-PWR-3200AC
PS5 (Active)
C9400-PWR-3200DC
The switch meets all the required conditions for an n+1 redundant mode with a normal protected state.
• It is in an n+1 redundant mode, because one power supply module is configured as standby.
It also meets all the n+1 redundant mode conditions:
• It is in a normal protected state, because:
Total standby output power (3200 W) is lesser than total active output power (22400).
and
Total active output power (22400) is greater than the required budgeted power (3505)

Other valid configuration options for the n+1 mode:
• All installed modules are AC-input power supply modules of the same capacity and with the same
AC-input voltage voltage level; one module is configured as standby.

C9400-PWR-3200DC
• A mix of AC-input and DC-input power supply modules are installed and all modules are of the
same capacity.
In the same output, see
Capacity
• All installed AC-input power supply modules have an AC-input voltage of 220 VAC (the
fields for the AC-input modules reflect this.
