2.13 Installing the Power Supply
There are three power connectors on your S8212. TYAN® recommends that
you have an EPS12V power supply which has one 24-pin, two 8-pin and one 4-
pin power connectors.
PW3: 2x2 pin power
Connector for DIMMs.
PW2/PW4: 8-pin EPS 12V
power connector for CPU
loading.
PW1: 24-pin power
connector.
Applying power to the board
a. Connect the EPS12V 8-pin power connectors. Both PW2 and PW4 are
for CPU loading. With light load processors, such as HE model, one
8pin power connector is ok. With SE model processors, the PW4 is
required to be plugged.
b.
Connect the EPS12V 24-pin power connector.
c. Connect the EPS12V 4-pin power connector.PW3 is for DIMMs, it is
required to be connected to PSU all the time.
d.
Connect power cable to power supply to power outlet
NOTE
YOU MUST unplug the power supply from the wall outlet
before plugging the power cables to motherboard connectors.
