B-8 Dell Workstation Mini Tower Systems User’s GuideMouse ConnectorIf you reconfigure your hardware, you may need pinnumber and signal information for the mouse connector.Figure B-6 illustrates the pin numbers for the mouseconnector, and Table B-6 lists and defines the pin assign-ments and interface signals for the mouse connector.Figure B-6. Pin Numbers for the MouseConnectorVideo ConnectorFor information on your video connector, see the manu-facturer’s specifications that accompanied your videocard.NIC ConnectorYour system contains an RJ45 connector (see Figure B-7)on the back panel for attaching an unshielded twisted pair(UTP) Ethernet cable, which is used in 10BASE-T and100BASE-TX networks. The network interface control-ler (NIC) provides all the functions normally handled bya separate network expansion card. To connect your sys-tem to and configure it for use on an Ethernet network,see Chapter 5, “Using the Network Interface Controller.”Figure B-7. NIC ConnectorTable B-5.
