2.7 Jumpers Setup

The illustration shows how jumpers are

setup. When the jumper cap is placed on

pins, the jumper is “SHORT”. If no jumper

cap is placed on the pins, the jumper is

“OPEN”. The illustration shows a 3-pin

jumper whose pin1 and pin2 are “SHORT”.

+5VSB (standby) for PS/2 or

USB wake up events.

Note: To select +5VSB, it requires 2 Amp and higher standby current provided by

power supply.

Note: When you connect speakers in back panel and front panel at the same time,

1. If the jumpers JL1 and JR1 are short (see fig. 1), both front panel and

rear panel audio connectors can work.

2. If both jumper caps on JL1 and JR1 are removed (see fig. 2), only front

panel audio works.

However, it requires your front panel to support the function.
