P5TX–Apro User's Manual
2: Using Your Mainboard – 2.8
Case Security
The mainboard has a case security feature that will warn if the
system case or 'chassis' has been opened since the last time the
system was used. There is a photoelectric cell mounted on the
mainboard that is active when the system is turned off and will
detect the case being opened. The next time you turn the system
on a warning message will appear on screen during the POST
(Power On Self Test) before the Operating System loads.
The J18 connector on the mainboard connects to a chassis
intrusion signal cable.
Cooling Fan Connectors
There are three cooling fan connectors on the mainboard that
support cooling fans with power management features. If you
connect this type of fan, and the 'CPU FAN Off In Suspend' line
in the CMOS Setup utility's Power Management Setup section is
set to Enabled, the system will turn the fans off when the system
is in Suspend mode.
Modem Wake-Up
The J19 connector on the mainboard is for connecting a signal
cable from a modem that supports a modem ring system wake
up feature. With such a modem installed and connected to the
mainboard via this connector, the system will wake up from Sus-
pend mode when an incoming call is received by the modem.
The 'Ring-In Event' line in the CMOS Setup utility's Power
Management Setup section must be set to Enabled for this fea-
ture to function.
Power Supply Selection
There are two power supply connectors on the mainboard.
One is for a standard PS/2–type power supply and the other for
an ATX power supply. You must indicate which type is connected
to the mainboard for power management purposes. You do this
by setting the 'Power Supply Type' line in the CMOS Setup
utility's Power Management Setup section to the correct type.
