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 port	Used to attach an external modem, a serial printer, or other devices that use a
	9-pin serial port.
