14. ATX Power Supply Connector (20-pin ATXPWR)

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

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

Find the proper orientation and push down firmly but gently 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 powering

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.

15. Chassis Intrusion Alarm Lead (optional) (4-1 pin CHASIS)

This requires an external detection mechanism such as a chassis intrusion moni-

tor/sensor or microswitch. The sensor is triggered when a high level signal is

sent to the Chassis Signal lead, which occurs when a panel switch or light detec-

tor is triggered. This function requires the optional CIDB chassis sensor module

to be installed (See 7. APPENDIX).

NOTE: When the chassis is opened, connect/short the Chassis Signal pin to the

+5VSB pin. When the chassis is closed, connect/short the Chassis Signal pin to

the Ground pin.
