Input/output connectors Expansion Slots: Cables to the external connectors on installed ISA and PCI adapters connect here. For information about expansion slots and adapters, see "Working with adapters" on page 79. Microphone: This connector is used to attach a microphone to your server when you want to record voice or other sounds on the hard disk. This connector can also be used by speech-recognition software. Audio Line In: This connector is used to send audio signals from an external device (such as a CD player or stereo) to your server so that the signals can be recorded on the hard disk. Audio Line Out: This connector is used to send audio signals from your server to external devices, such as stereo-powered speakers with built-in amplifiers, headphones, multimedia keyboards, or the audio line-in jack on a stereo system. To hear audio, you must connect one of these external devices to the audio line-out connector on your server. Note: The internal speaker in your server is disabled when an external speaker is attached to the audio line-out connector on your server. There is no playback capability through the internal speaker. Ethernet Connector: An unshielded, twisted-pair (UTP) cable with an RJ-45 connector attaches here to the 10/100 Ethernet controller on the system board. For information on the Ethernet controller, see "Configuring the Ethernet controller" on page 59. For more information on the Ethernet connector, see "Ethernet connector" on page 143. For information on cables, see Appendix A, "Ethernet cable specifications" on page 271. Parallel Connector: A signal cable for a parallel device, such as a printer, connects here. Chapter 1.
