In case of failure in the combined mode, each operational power supply increases its output. If the output
power does not meet system requirements and the power supply autolc shutdown command is disabled,
then all the operational power supply modules may be overloaded and go into overcurrent shutdown. All
system power is then lost. We recommend enabling the power supply autolc shutdown command.
Other valid configuration options for the combined mode:
• All installed modules are DC-input power supply modules; all modules are configured as active.
• All installed modules are AC-input power supply modules of the same capacity and with the same
AC-input voltage voltage level; all modules are configured as active.
Example: Combined Mode and State (DC-Input Only)
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
and type (C9400-PWR-3200DC) have been installed in slots 1 through 8.

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. There
are no other conditions to consider for this setup.
The following is sample output of this setup (the show power privileged EXEC command):
