2.3.11 Panel Connector

The Panel (multifunction) connector is
a 20-pin connector marked as PANEL
on the board. Attach the power LED,
keylock, speaker, SPWR, IDE LED
and reset switch to the corresponding
pins as shown in the figure. Some
housings have a five-pin connector for
the keylock and power LED. Since
power LED and keylock are aligned
together, you can still use this kind of
connector. If your
supports ACPI specification, the ACPI
& Power LED will keep flashing if you
have enabled "suspend mode" item in
BIOS Setup.
Caution: The specification of IDE cable is
maximum 46cm (18 inches), make sure your
cable does not excess this length.
Caution: For better signal quality, it is
recommended to set far end side device to
master mode and follow the suggested
sequence to install your new device. Please
refer to the following figure.
