B-3
Note
Figure B-1 shows three motherboard layouts. The motherboard has the
features shown above except for the LAN3 and LAN4 ports and their associated
jumpers.
Note
Jumpers not identified are for test purposes only.
Caution
There is a danger of explosion if the onboard battery is installed upside
down (which reverses its polarities). This battery must be replaced only with the same
or an equivalent type recommended by the manufacturer (CR2032).
Caution
To prevent damage to the power supply or motherboard, use a power
supply with a 24-pin and one 8-pin power connectors. Be sure to connect these
connectors to the 24-pin (JPW1) and one 8-pin (JPW2) power connectors on the
motherboard. Failure to do so voids the manufacturer warranty on your power supply
and motherboard.
Note
When the LED4 LED is on, the onboard power connection is on. Be sure to
unplug the power cables before removing or installing components.
