CD Header

A4-pin CD header (CD1) and a Front Panel Audio header (JC2) are included on the serverboard. These headers allow you to use the on- board sound for audio CD playback. Connect an audio cable from your CD drive to the CD header that fits your cable's connector. Only one CD header can be used at any time.

Front Panel Audio Control

When front panel headphones are plugged in, the back panel audio out- put is disabled. This is done through the FP Audio header (JC2). If the front panel interface card is not connected to the front panel audio header, jump- ers should be installed on pin pairs 1-2, 5-6, and 9-10 of the Audio FP header. If these jumpers are not installed, the back panel line out connector will be disabled, and pin 1 of the microphone in will be left floating, which can lead to excessive back panel microphone noise and crosstalk. See the table at right for pin definitions.
