Reset Switch
Supporting the reset function requires the connection of pin five and pin seven to a momentary-
contact switch that is normally opened. When the switch is closed, the board resets and runs
POST.
Power Switch
Supporting the power on/off function requires the connection of pin six and pin eight to a
momentary-contact switch that is normally opened. The switch should maintain contact for at
least 50 ms to signal the power supply to switch on or off. The time requirement is due to
internal de-bounce circuitry. After receiving a power on/off signal, at least two seconds elapse
before the power supply recognizes another on/off signal.
LAN LED
Connecting pin 12 and pin 14 to a LAN LED provides visual indication that data is being read from
or written to the LAN drive.
IDE Connector
The main board supports four high data transfer SATA ports with each runs up to 3.0 Gb/s. To get
better system performance, users can connect the CD-ROM to the IDE channel, and set up the
hard drives on the SATA ports.
IDE devices enclose jumpers or switches used to set the IDE device as Master or Slave. When
installing two IDE devices by one cable, ensure that one device is set as Master and the other as
Slave.
