7. Connecting ATX and AGP Pro Power Connector
6. Install DIMM Modules
8. Redundant SPS Monitoring Connector
9. Connecting IDE & FDD Cable
This motherboard has three 168-pin
DIMM sockets
that allow you to install PC100 or
PC133
memory up to 3GB. The DX34-U / DX34 Plus-U supports not only SDRAM but
also ECC or Registered DRAM.
The DX34-U / DX34 Plus-U uses standard ATX power connector. The 6-pin AGP Pro
Power connector provides extra +5V and +3.3V power for AGP Pro VGA card. Make sure
you plug in the right direction.
This motherboard implements Redundant SPS monitoring connector to provide hardware
monitoring signals. It is feasible to install an additional 337-watt power supply module
(optional with AOpen Server Housing) in a hot swappable configuration. If any SPS failed,
a signal will be sent to a hardware monitoring device.
Connect 34-pin floppy cable and 40-pin ATA100 or ATA33 IDE cable to floppy connector

. Pin1 of cable is normally marked with red color. Be
careful of the pin1 orientation. Wrong orientation may cause system damage.
