PANEL1 Connector
PW-BN
a. IDE activity LED (HD-LED)
This connector supplies power to the cabinet's IDE activity LED.
Read and write activity by devices connected to the Primary or
Secondary IDE connectors will cause the LED to light up.
b. Power LED Lead (PE_BN)
The system power LED lights when the system's power is on.
c. SMI Suspend Switch Lead (SMI)
This allows the user to manually place the system into a suspend
mode or "Green" mode where systematic activity will be instantly
decreased to save electricity and expand the life of certain compo-
nents when the system is not in use. This 2-pin connector (see
the figure below) connects to the case-mounted suspend switch.
If you do not have a switch for the connector, you may use the
"Turbo Switch" since it does not have a function. SMI is acti-
vated when it detects a short to open moment and therefore leav-
ing it shorted will not cause any problems. It may require one or
two pushes depending on the position of the switch. Wake-up
can be controlled by settings in the BIOS but the keyboard will
always allow wake-up (the SMI lead cannot wake-up the system).
If you want to use this connector,"Suspend Switch" in the Power
Management Setup of the BIOS SOFTWARE section should be
on the default setting of Enable
d. Reset Switch Lead (RST)
This 2-pin connector connects to the case-mounted reset switch
for rebooting your computer without having to turn off your power
switch. This is a preferred method of rebooting in order to pro-
long the life of the system's power supply.
