Desktop Board Features The onboard audio headers include the following: • Front panel audio (a 2 x 5 pin header that provides headphone and mic in signals for front panel audio connectors) • S/PDIF audio header (1 x 4 pin header) • Internal mono speaker header (1 x 2 pin header) Front panel headphone output is supported by a separate audio channel pair, allowing multi-streaming audio configurations such as simultaneous 6-channel (5.1) surround sound playback and stereo audio conferencing (through speakers connected to the back panel audio connectors and a headset connected to front panel audio connectors). The onboard internal mono speaker header allows connection to an internal, lowpower speaker for basic system sound capability. The subsystem is capable of driving a target speaker load of 8 Ω at 1 W (rms) or 4 Ω at 1.5 W (rms). The onboard S/PDIF header allows connection to coaxial or optical adapters for digital audio output. The back panel audio connectors (see Figure 21 on page 47) are configurable through the audio device drivers. Audio software and drivers are available from http://downloadcenter.intel.com/. LAN Subsystem The LAN subsystem includes: • Intel 82578DC Gigabit (10/100/1000 Mb/s) Ethernet LAN controller • RJ-45 LAN connector with integrated status LEDs LAN software and drivers are available at http://downloadcenter.intel.com/. Two LEDs are built into the RJ-45 LAN connector located on the back panel (see Figure 2). These LEDs indicate the status of the LAN as shown in Table 3. Figure 2. LAN Connector LEDs 17
