Dell OptiPlex 7070 Ultra Setup and Specifications

Powering the system

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.
