23. Chassis Intrusion Lead (2-pin CHA)

This lead is for a chassis designed for chassis intrusion detection. After-market

toggle switches may also be installed to the chassis panel or on any removable

components. Two wires should be available from the chassis to connect to this

lead. When any chassis component is removed, the contact should open and the

motherboard will record a chassis intrusion event. If the chassis intrusion con-

nector is not used, a jumper cap must be placed over the pins to prevent unnec-

essary power loss.

24) ATX Power Supply Connector (20-pin block ATXPWR)

This connector connects to an ATX power supply. The plug from the power sup-

ply will only insert in one orientation because of the different hole sizes. Find the

proper orientation and push down firmly making sure that the pins are aligned.

IMPORTANT: Make sure that your ATX power supply can supply at least 10mA

on the +5-volt standby lead (+5VSB). You may experience difficulty in power-

ing ON your system if your power supply cannot support the load. For Wake-

On-LAN support, your ATX power supply must supply at least 720mA +5VSB.
