Powering The System; Type-C Display Settings - Dell OptiPlex 7070 Ultra Setup And Specifications

OptiPlex 7070 Ultra can be powered using a AC adapter (4.5 mm input power source) or through the USB Type-C cable connected to
your display. During normal operation, when the device is connected with a single power source (primary power source), connecting a
second power source and disconnecting the primary power source will shut down the device. However, if the secondary power source is
disconnected while the primary power source is connected, the system continues to operate normally.
When the device is powered with both the power sources—AC adapter and USB Type-C cable, the AC adapter is the primary power
source and USB Type-C is the secondary power source. Disconnecting the AC adapter will shut down the system. If the secondary power
source is disconnected, the system continues to operate normally.
NOTE: Hotswap between the AC adapter and USB Type-C power source is not supported.

Type-C display settings
When using a Dell USB Type-C display to power on your OptiPlex 7070 Ultra, to avoid any power loss to the device when the display is
turned off or on Standby mode, ensure that the Always on USB-C Charging setting on the display is enabled.
On turning on the Dell USB Type-C display for the first time, the Easy initial setup is displayed. Click Yes, to enable the Always on
USB-C charging option.
If you miss enabling the option on Easy Initial setup window, then you can enable the setting using the on-screen display menu available on
the display. For more information on enabling the option, see the documentation that is shipped with your display.
NOTE: The "USB-C Always On Charging" firmware option may not be present on all Dell USB Type-C displays. You can
enable the USB-C Always On charging feature only after you update the firmware. Download the Dell display firmware,
at Dell.com/support.
