Jumpers, Switches, and Connectors Dell PowerEdge 750 Systems Installation and Troubleshooting Guide
JumpersA General Explanation
System Board Jumpers
System Board Connectors
Riser Board Connectors
Disabling a Forgotten Password
This section provides specific information about the system jumpers. It also provides some basic information on jumpers and switches and describes the connectors on the various boards in the system.
JumpersA General Explanation
Jumpers provide a convenient and reversible way of reconfiguring the circuitry on a printed circuit board. When reconfiguring the system, you may need to change jumper settings on circuit boards or drives.
Jumpers
Jumpers are small blocks on a circuit board with two or more pins emerging from them. Plastic plugs containing a wire fit down over the pins. The wire connects the pins and creates a circuit. To change a jumper setting, pull the plug off its pin(s) and carefully fit it down onto the pin(s) indicated. Figure A-1 shows an example of a jumper.
Figure A-1. Example Jumper
A jumper is referred to as open or unjumpered when the plug is pushed down over only one pin or if there is no plug at all. When the plug is pushed down over two pins, the jumper is referred to as jumpered. The jumper setting is often shown in text as two numbers, such as 12. The number 1 is printed on the circuit board with a triangle so that you can identify each pin number based on the location of pin 1.
Figure A-2 shows the location and default settings of the server-module jumper blocks. See Table A-1 for the designations, default settings, and functions of the jumpers.
System Board Jumpers
Figure A-2 shows the location of the configuration jumpers on the system board. Table A-1 lists the jumpers settings.

I/O Connectors
I/O connectors are the gateways that the system uses to communicate with external devices, such as a keyboard, mouse, printer, 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 connectors on the system.
Figure B-1. I/O Connectors
Table B-1 shows the icons used to label the connectors on the system.
Table B-1. I/O Connector Icons

Serial connectors support devices such as external modems, printers, and mice that require serial data transmission. Serial connectors are also used for console redirection. The serial connector uses a 9-pin D-subminiature connector.
Icon Connector
Serial connector
Mouse connector
Keyboard connector
Video connector
USB connector
Network adapter connector
Serial Connector Autoconfiguration
The default designation of the integrated serial connector is COM1. When you add an expansion card containing a serial connector that has the same designation as the integrated connector, the system's autoconfiguration feature remaps (reassigns) the integrated serial connector to the next available designation. Both the new and the remapped COM connectors share the same IRQ setting. COM1 and COM3 share IRQ4, while COM2 and COM4 share IRQ3.
Before adding a card that remaps the COM connectors, check the documentation that came with the software to make sure that the software can accommodate the new COM connector designation.
Figure B-2 illustrates the pin numbers for the serial connector and Table B-2 defines the pin assignments for the connector.

Finding Software Solutions Dell PowerEdge 750 Systems Installation and Troubleshooting Guide
Before You Begin
Troubleshooting Errors and Conflicts
Software problems can be caused by:
l Improper installation or configuration of an application
l Application conflicts
l Input errors
l Interrupt assignment conflicts
Ensure that you are installing the software application according to the software manufacturer's recommended procedures. If a problem occurs after you install the software, you might need to troubleshoot your software application and your system.
See the documentation that accompanied the software or contact the software manufacturer for detailed troubleshooting information.
Before You Begin
l Scan the software media with antivirus software.
l Read the software documentation before you run the installation utility.
l Be prepared to respond to prompts from the installation utility.
The installation utility may require you to enter information about your system, such as how the operating system is configured, and the type of peripherals that are connected to the system. Have this information available before running the installation utility.
Troubleshooting Errors and Conflicts
While configuring and running software, problems might occur that are caused by input errors, application conflicts, and/or IRQ assignment conflicts. The problems are sometimes indicated by error messages.
Error messages are generated by system hardware or software. "Indicators, Messages, and Codes" provides information about error messages that are hardware-based. If you receive an error message that is not listed, see your operating system or software program documentation for troubleshooting information.
Input Errors
Pressing a specific key or set of keys at the wrong time may produce unexpected results. See the documentation that came with the software application to ensure that the values or characters you are entering are valid.
Ensure that your operating system is configured properly to run the application. Remember that whenever you change the parameters of the operating system, the changes can conflict with an application's operating requirements. After you configure the operating system, you may need to reinstall or reconfigure a software application so that it can run properly in its new environment.
NOTE: If all of the system diagnostic tests complete successfully, then the problem is most likely caused by the software and not the hardware.
Application Conflicts
Some applications can leave unnecessary files or data behind after they are deleted from your system. Device drivers can also create application errors. If application errors occur, see your application device driver or operating system documentation for troubleshooting information.
IRQ Assignment Conflicts
Most PCI devices can share an IRQ with another device, but they cannot use an IRQ simultaneously. To avoid this type of conflict, see the documentation for each PCI device for specific IRQ requirements.
