9. WOL (Wake on LAN) Connector
To use Wake On LAN function, you must have an Ethernet card with chipset that supports
this feature, and connect a cable from LAN card to motherboard WOL connector. The
system identification information (probably IP address) is stored on network card and
because there is a lot of traffic on the Ethernet, you need to install network management
software, such as ADM, for the checking of how to wake up the system.
This motherboard provides two serial ports. One of them is on back panel connector, and
the other is on the upper middle of board. With proper cable, you can connect it to the back
panel of chassis.
6. Advanced 64-bit PCI-X Slots
DXPN-U provides four 64-bit/66/100MHz PCI-X and one 32-bit/33MHz PCI slots. The
64-bit/66/100MHz PCI-X slots maximizes I/O bandwidth for the next generation 64-bit PCI-X
cards that support 100MHz bus. The PCI-X specification 1.0a allows full peer-to-peer
transactions between PCI buses and provides options for intelligent I/O and server
management cards.

14. JP3 Clear CMOS Jumper
You can clear CMOS to restore system default setting. To
clear the CMOS, follow the procedure below.
1. Turn off the system and unplug the AC power.
2. Remove ATX power cable from connector PWR2.
3. Locate JP3 and short pins 2-3 for a few seconds.
4. Return JP3 to its normal setting by shorting pin
1 & pin 2.
5. Connect ATX power cable back to connector PWR2.
Tip: When should I Clear CMOS?
1. Boot fails because of overclocking…
2. Forget password…
