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.
PCI-X Slot Speed
Jumpers JPX1A and JPX2A on the
H8DAE-2 can be used to change the
speed of PCI-X slot #1 and PCI-X slot
#2, respectively. See the tables on the
right for jumper settings.
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.
IEEE 1394 Enable/Disable
JPI1 is used to enable or disable the
onboard IEEE (Firewire) headers. See
the table on right for jumper settings.
