States
The examples in this section illustrate different power supply setups. They describe how the Power Supply
Module Installation Considerations in the Cisco Catalyst 9400 Series Switches Hardware Installation Guide
and the Operating States section in this document affect possible power supply mode configurations. Both
combined and redundant power supply modes, and the resulting operating states are covered.
Example: Combined Mode and State (AC- and DC-Input)
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 slots 5 through 8 have DC-input power supply modules.

All available power supply modules are active and sharing power and can operate at up to 100 percent capacity.
The device is in a combined operating state, because a standby power supply module is not configured. This
is a valid configuration for the combined mode, because:
• All installed power supply modules are active and available.
In the sample output, see Status= active.
• All installed power supply modules are of the same capacity.
In the sample output, see Capacity = 3200 W.
• All installed AC-input power supply modules have an AC-input voltage of 220 VAC
In the sample output, the Capacity fields for the AC-input modules reflect this.
The following is sample output of this setup (the show power privileged EXEC command):
