Chapter 2: Installation AC97 AC97 provides high quality onboard audio. The H8DCE features 6-chan- nel (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 sec- tion for details) and the BIOS setting for the Audio Codec (under South Bridge Confi guration). In addition, Line In (blue port): Surround L/R Line Out (green port): Front L/R MIC (pink port): Center/Subwoofer there are also CD1 and AUX1 connec- tors 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. Notes: NC indicates no connection. Pins 6 and 10 are not active when a header is used for front side audio access. 2-15 Audio Header Pin Defi nitions (J26) Pin# Defi nition 1 MIC 2 Ground 3 Vcc 4 NC 5 Line Out (Right) 6 Onboard Line Out (Right) 7 NC 8 Key 9 Line Out (Left) 10 Onboard Line Out (Left)
