Using Your Mainboard – 2.8
Cooling Fan Connectors
There are three cooling fan power connectors on the main-
board. One is for the CPU cooling fan (J3), one for a power sup-
ply fan (J1) and one for a case-mounted or “chassis” cooling fan
(J19). When the system enters Suspend mode, the CPU cooling
fan and power supply fan will shut off. The case fan is not turned
off in order to maintain air circulation inside the case.
Modem Wake-Up
The J18 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.
LAN Wake-Up
The J17 connector on the mainboard is for connecting a signal
cable from a LAN card that supports a LAN wake-up feature.
When a LAN card that supports this is installed and connected to
the mainboard via this connector, the system will wake up from
Suspend mode when the system is accessed via the LAN.
ATX Power Supply
With an ATX power supply, the system will turn the power
off automatically when exiting Windows95.
UltraDMA Hard Disk Drive Support
This mainboard supports hard disks that use UltraDMA data
transfer. You attach an UltraDMA drive to one of the IDE cables.
If you use the Optimum Settings feature in the CMOS Setup
utility the system will automatically detect the drive and config-
ure the system to use it.
