Installing and Replacing Desktop Board Components

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.
