Jumpers—A General Explanation

System Board Jumpers

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.



Jumpers—A 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 Jumpers



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 1–2. The number 1 is printed on the

circuit board 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 system jumper blocks. See TableA-1 for the designations, default settings, and functions of the

system's 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.

Figure A-2. System Board Jumpers



CAUTION: Ensure that the system is turned off before you change a jumper setting. Otherwise, damage to the system or unpredictable results

may occur.

NOTE: For the full name of an abbreviation or acronym used in this table, see "Abbreviations and Acronyms."

The system's software security features include a system password and a setup password, which are discussed in detail in "Using the System Setup Program"

in your User's Guide. The password jumper enables these password features or disables them and clears any password(s) currently in use.



1. Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet.

2. Remove the cover (see "Removing the Cover" in "Troubleshooting Your System").

3. Lay the system on its right side.

4. Remove the password jumper plug.



See FigureA-2 to locate the password jumper on the system board.

5. Stand the system upright.

6. Install the cover (see "Installing the Cover" in "Troubleshooting Your System").

7. Reconnect the system to its electrical outlet and turn the system on, including any attached peripherals.



The existing passwords are not disabled (erased) until the system boots with the password jumper plug removed. However, before you assign a new

system and/or setup password, you must install the jumper plug.



8. Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet.

9. Remove the cover (see "Removing the Cover" in "Troubleshooting Your System").

10. Lay the system on its right side.

11. Install the password jumper plug.



See FigureA-2 to locate the password jumper on the system board.

12. Stand the system upright.

13. Install the cover (see "Installing the Cover" in "Troubleshooting Your System").

14. Reconnect the system to its electrical outlet and turn the system on, including any attached peripherals.

15. Assign a new system and/or setup password.



To assign a new password using the System Setup program, see "Using the System Setup Program" in your User's Guide.



CAUTION: Before you perform this procedure, see "Safety First—For You and Your System" in "Troubleshooting Your System."

CAUTION: See "Protecting Against Electrostatic Discharge" in the safety instructions in your System Information Guide.

NOTE: If you assign a new system and/or setup password with the jumper plug still removed, the system disables the new password(s) the next

time it boots.

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.

Serial Connector



Serial connectors support devices such as external modems, printers, and mice that require serial data transmission. The serial connector uses a 9-pin D-

subminiature 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.

Figure B-2. Serial Connector Pin Numbers



Table B-2. Serial Connector Pin Assignments



Parallel Connector



The integrated parallel connector, intended primarily for use by printers that require data in parallel format, uses a 25-pin D-subminiature connector on the

system's back panel. The default designation of the system's parallel connector is LPT1. If you add an expansion card containing a parallel connector

configured as LPT1 (IRQ7, I/O address 378h), use the System Setup program to remap the integrated parallel connector. See "Using the System Setup

Program" in the User's Guide. FigureB-3 illustrates the pin numbers for the parallel connector and TableB-3 defines the pin assignments for the connector.

Figure B-3. Parallel Connector Pin Numbers



NIC connector

NOTE: If two COM connectors share an IRQ setting, you may not be able to use them both at the same time. In addition, if you install one or more

expansion cards with serial connectors designated as COM1 and COM3, the integrated serial connector is disabled.
