2.5 Electrical Considerations
2.5.1 Power Supply Considerations
CAUTION
The external 19 V DC jack is the primary power input connector of Intel Next Unit of
Computing Board DCP847SKE. However, the board also provides an internal 1 x 2
power connector that can be used in custom-developed systems that have an internal
power supply.
There is no isolation circuitry between the external 19 V DC jack and the internal 1 x 2
power connector. It is the system integrator’s responsibility to ensure no more than
one power supply unit is or can be attached to the board at any time and to ensure the
external 19 V DC jack is covered if the internal 1 x 2 power connector is to be used. A
plastic lid for the external 19 V DC jack is provided in the accessories box shall it be
useful to the system integrator for this purpose.
Simultaneous connection of both external and internal power supply units could result
in potential damage to the board, power supplies, or other hardware.
System power requirements will depend on actual system configurations chosen by the
integrator, as well as end user expansion preferences. It is the system integrator’s
responsibility to ensure an appropriate power budget for the system configuration is
properly assessed based on the system-level components chosen.
