Input / output connectors - Netfinity 3500

Troubleshooting

Problem

The internal speaker in the server is disabled when an external speaker is attached to the audio line-out connector on the server. There is no playback capability through the internal speaker.

Resolving The Problem

Input / Output conncection

.	Power Connector: The server power cable connects here.
	Mouse Connector: The mouse cable connects here. This connector is sometimes called the auxiliary-device port.
	Universal Serial Bus (USB) Connectors: Attach I/O devices with universal serial bus (USB) connectors to USB connector 1 and connector 2. You need a 4-pin cable to connect a device to these ports.
	Parallel Connector: A signal cable for a parallel device, such as a printer, connects here.
	Audio Line In: This connector is used to send audio signals from an external device (such as a CD player or stereo) to the server so that the signals can be recorded on the hard disk.
	SCSI Connector: SCSI devices attach here. For more information, see "Adding External SCSI Devices", "Attaching External Options", and "SCSI Connectors".
	Microphone: This connector is used to attach a microphone to the 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 Out: This connector is used to send audio signals from the 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 the server.

NOTE The internal speaker in the server is disabled when an external speaker is attached to the audio line-out connector on the 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 more information about cables, see "Ethernet Cable Specifications".
	Serial Connectors: Attach signal cables for modems or other serial devices to the 9-pin serial connectors of serial ports 1 and 2. See "Serial Port Connectors" for port assignment information.
	Keyboard Connector: The keyboard cable connects here.
	Monitor Connector: The monitor signal cable connects here.
.	Expansion Slots: Cables to the external connectors on installed ISA and PCI adapters connect here. For information about expansion slots and adapters, see "Adapters".

NOTE The monitor connector is located on the graphics adapter installed in slot 1.

Keyboard and Mouse Connectors
The server provides one keyboard port and one auxiliary-device port. An auxiliary device can be a mouse or other pointing device.

Table 5 shows the pin-number assignments for the keyboard and auxiliary-device port connectors.

Pin	Signal
1	Data
2	Not connected
3	Ground
4	+5 V dc
5	Clock
6	Not connected
