Caution To avoid risk of explosion, do not replace the battery (JBAT1) with an incorrect
battery type. Dispose of used batteries according to the battery instructions.
Cautions To prevent damage to the power supply or motherboard, use a power supply with
a 20-pin and two 8-pin power connectors. Be sure to connect these connectors to the 20-pin
(JPW1) and two 8-pin (JPW2, JPW3) power connectors on the motherboard. Failure to do
so voids the manufacturer warranty on your power supply and motherboard.
To provide adequate power to the add-on cards installed on the motherboard, connect the
UIOP PWR connector to the power supply for these cards to work properly.
Note When the LE1 LED is on, the onboard power connection is on. Be sure to unplug
the power cables before removing or installing components.
