Connector Description
Audio line-in connector Used to receive audio signals from an external audio device, such as a stereo
system. When you attach an external audio device, a cable connects the audio
line-out connector of the device to the audio line-in connector of the server.
Audio line-out connector Used to send audio signals from the server to external devices, such as powered
stereo speakers (speakers with built-in amplifiers), headphones, multimedia
keyboards, or the audio line-in connector on a stereo system or other external
recording device.
DisplayPort connector Used to attach a high-performance monitor, a direct-drive monitor, or other devices
that use a DisplayPort connector.
Ethernet connector Used to attach an Ethernet cable for a local area network (LAN).
Note: To operate the server within FCC Class B limits, use a Category 5 Ethernet
cable.
Microphone connector Used to attach a microphone to your server when you want to record sound or if
you use speech-recognition software.
Serial connector Used to attach an external modem, a serial printer, or other devices that use a
9-pin serial connector.
