Onboard Speaker Enable/Disable
The JD1 header allows you to use
either an external speaker or the
internal (onboard) speaker. To use
the internal onboard speaker, close
pins 6 and 7 with a jumper. To use an
external speaker, remove the jumper
and connect the speaker wires to pins
4 (+5V) and 7 (control signal). See the
table on the right for settings and the
table associated with the Power LED/
Keylock/Speaker connection (previ-
ous section) for jumper settings.

Note:
JPX1A controls the speed for PCI-X slot #1
and JPX1B controls the speed for PCI-X slot #2.
The default setting for both is Auto.
Note:
Pins 4-7 are used only for the on-
board speaker.
USB Power Select
Jumper JPUSB is used to select the
power state for the USB ports. The
Standard setting means power is ap-
plied to the ports only when the system
is powered on. The Dual Power setting
will allow the USB ports to have power
whenever the system's AC power cord
is connected, regardless of whether
the system is powered on or not. See
the table on right for jumper settings.
