Audio Header; Power Supply Fail Alarm Reset - Supermicro H8DCE-HTe User Manual

AC97
AC97 provides high quality onboard
audio. The H8DCE-HTe features
6-channel (5.1) sound for front L&R,
rear L&R, center and subwoofer
speakers. This feature is activated
with software included on the CD-
ROM that came with the serverboard.
Sound is output through the Line In,
Line Out and MIC jacks (see at right).
Activate AC97 with the JPAC jumper
(see next section for details) and the
BIOS setting for the Audio Codec
(under South Bridge Confi guration).
In addition, there are also CD1 and
AUX1 connectors on the board that
can be used for audio output.

Audio Header

The J26 header is used both as a
jumper and a cable connector. Jump
pins 5-6 and 9-10 to use the backpanel
jacks for AC97 audio output (see
Figure 2-3). J26 also gives you the
option of directing the audio output to
Line In/Line Out/ Mic jacks that may
be added to the front of the chassis
(requires additional hardware, not in-
cluded). See the table on the right for
pin defi nitions.

The system will notify you in the event

Supermicro redundant power supply
units are installed in the chassis. Con-
nect a microswitch to the JAR header
