7/ Internal Connectors

7.1. Power Connector

The mITX-HSW-S is designed to be supplied from a 2x12-pin ATX main power supply and a 2x2-pin +12 VDC power
supply.
Hot plugging any of the power connector is not allowed.
Hot plugging might damage the board. In other words, turn off main supply etc. to make
sure all the power lines are turned off when connecting to the motherboard.
