6) USB2 / CNRUSB Selection (J3-J3-/OC3)
The CNR slot can support an optional USB hub CNR card. Three jumpers are
used to control selection of USB or CNR functions: J3-, J3+ and OC3. The
factory default setting is for standard USB2 control. If a USB hub CNR card is
used, reset these jumpers to CNRUSB setting shown below.
IMPORTANT! Always set all three jumpers accordingly when selecting a device.
5) Onboard Audio Setting (ADN) (audio models only)
The onboard Audio Codec may be enabled or disabled using these jumpers.
Disable the onboard Audio Codec if using a PCI audio card on any of the
expansion slots or a primary audio/modem CNR on a CNR slot (see CNR Slot
later in this section).
