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
• A mix of AC-input and DC-input power supply modules are installed where all modules are of the same

The table below represents the two rows of power supply slots in a Cisco Catalyst 9400 Series chassis. Power
supply slots are indicated as PS1, PS2, and so on. For this example, power supply modules of the same capacity
(3200W) have been installed in slots 1 through 8. Slots 1 through 4 have AC-input power supply modules
and all are configured as active. Slots 5 through 8 have DC-input power supply modules and all are configured
as standby.

The device meets all the required conditions for an n+n redundant mode with a full protected state.
• It is in an n+n redundant mode, because n number of power supply modules are configured as active,
• It is in a full protected state, because:

It also meets all the n+n redundant mode conditions:
• 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.
Total active output power (12800) is greater than the required budgeted power (3505).
