I/O connectors are the gateways that the system uses to communicate with external devices, such as a keyboard, mouse, or monitor. This section describes the various connectors on your system. If you reconfigure the hardware connected to the system, you may also need the pin number and signal information for these connectors. Figure B-1 illustrates the ports and connectors on the system.
Figure B-1. I/O Ports and Connectors
Table B-1 shows the icons used to label the connectors on the system.
The serial connector uses a 9-pin D-subminiature connector. See the documentation for the ERA/MC controller for information on using the serial port for configuration.
Figure B-2 illustrates the pin numbers for the serial connector and Table B-2 defines the pin assignments for the connector.
The PS/2-compatible keyboard and mouse cables attach to 6-pin, miniature DIN connectors. Figure B-3 illustrates the pin numbers for these connectors and Table B-3 defines the pin assignments for these connectors.
Figure B-3. Keyboard and Mouse Connector Pin Numbers
You can attach a VGA-compatible monitor to the system's integrated video controller using a 15-pin high-density D-subminiature connector.
Figure B-4 illustrates the pin numbers for the video connector and Table B-4 defines the pin assignments for the connector.
The system's USB connector supports USB-compliant devices such as diskette drives and CD drives (supplied by Dell). Figure B-5 illustrates the pin numbers for the USB connector and Table B-5 defines the pin assignments for the connector.
NOTICE: Do not attach a USB device that draws a maximum current of more than 500 mA per
channel or exceeds +5 V. Attaching devices that exceed this threshold may cause the USB
connectors to shut down. See the documentation that accompanied the USB devices for their
maximum current ratings.
The system's network switch module 10/100/1000 BASE-T uplink ports function as a separate network expansion card while providing fast communication between servers and workstations. Figure B-6 illustrates the pin numbers for the uplink ports and Table B-6 defines the pin assignments for the port.
The system's 10/100 management port allows you to manage the server modules. Figure B-7 illustrates the pin numbers for the management port and Table B-7 defines the pin assignments for the port.
NOTE: The analog rack interface port pin assignments are proprietary and are not
illustrated.
The serial null modem cable connector is a RJ11 connector that supports the use of a null modem cable to configure the network switch module. For additional information, see the network switch module documentation. Figure B-8 illustrates the serial null modem connector and Table B-8 defines the pin assignments for the connector.
