Connecting to a Power Supply
The board supports a wide range of input voltages from either of the following power
supply types:
• External Power Supply – the board can be powered with an 8-19 V DC external
power supply though the DC jack on the back panel (Figure 13, A). This connector
accepts dual-barrel plugs with an inner diameter (ID) of 2.5 mm and an outer
diameter (OD) of 5.5 mm, where the inner contact is +8 V DC (±10 %) through
+19 V DC (±10 %) and the shell is Ground. The maximum current rating for this
connector is 8 A.
• Internal Power Supply – the board can alternatively be powered through the
internal 1 x 2 power connector (Figure 13, B), where pin 1 is Ground and pin 2 is
+8 V DC (±10 %) through +19 V DC (±10 %). The maximum current rating for
this connector is 10 A.
Use of an external power supply is preferred. Total power consumption depends on
the system configuration selected by the integrator. Refer to the Intel Desktop Board
DN2800MT Technical Product Specification for further guidance.
