Jumpers and Connectors Dell PowerEdge 1750 Systems Installation and Troubleshooting Guide

  JumpersA General Explanation

  System Board Jumpers

  System Board Connectors

  SCSI Backplane Board Connectors

  Disabling a Forgotten Password

 This section provides specific information about the jumpers on the system board. It also provides some basic information on jumpers and switches and describes the connectors and sockets 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 the system board. You may also need to change jumper settings on expansion cards 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 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.

System Board Jumpers

 Figure A-2 shows the location and default settings of the jumper blocks on the system board. See Table A-1 for the designations, default settings, and functions of the system's jumpers.

Figure A-2. System Board Jumpers

CAUTION: Make sure the system is turned off before you change a jumper setting. Otherwise, damage to the system or unpredictable results may occur.

Disabling a Forgotten Password

 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 the User's Guide. A password jumper on the system board enables these password features or disables them and clears any password(s) currently in use.

 To disable a forgotten system password or setup password, perform the following steps.

1.  Open the system covers. See "Opening the System Covers" in "Troubleshooting Your System."

2.  See Figure A-2 for the location of the password jumper (labeled "PASSWD") on the system board.

3.  Remove the jumper plug from the PASSWD jumper.

4.  Close the system covers. See "Closing the System Covers" in "Troubleshooting Your System."

5.  Reconnect the system to an electrical outlet and turn it on.

 The existing passwords are not disabled (erased) until the system boots with the PASSWD jumper plug removed. However, before you assign a new system and/or setup password, you must reinstall the jumper plug.

6.  Repeat step 1.

7.  Install the jumper plug on the PASSWD jumper.

8.  Close the system covers, and then reconnect the system and peripherals to their electrical outlets and turn them on.

9.  Assign a new system and/or setup password.

 To assign a new passwords using the System Setup program, see "Assigning a System Password" in the User's Guide.

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-1illustrates the I/O connectors on the system back panel; Figure B-2 identifies the I/O connectors on the front panel.

Figure B-1. I/O Connectors on Back Panel

Figure B-2. I/O Connectors on Front Panel

 Table B-1 shows the icons used to label the connectors on the system.

Table B-1. I/O Connector Icon  

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-3 illustrates the pin numbers for the serial connector and Table B-2 defines the pin assignments for the connector.

Finding Software Solutions Dell PowerEdge 1750 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.

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.

Table 3-1. IRQ Assignments 

NOTE: If all of the system diagnostic tests complete successfully, then the problem is most likely caused by the software and not the hardware.

IRQ Line Assignment

IRQ0 System timer

IRQ1 Keyboard controller

IRQ2 Interrupt controller 1 to enable IRQ8 through IRQ15

IRQ3 Reserved for system use

Figure 6-5. Removing Memory Modules

Installing Microprocessors

To take advantage of future options in speed and functionality, you can add a second microprocessor or replace either the primary or secondary microprocessor.

Each microprocessor and its associated level 2 (L2) cache memory are contained in an FC-PGA2 package that is installed in a ZIF socket on the system board. The secondary microprocessor must have the same operating frequency and cache size as the primary microprocessor.

The following items are included in the microprocessor upgrade kit:

l A microprocessor

l A heat sink

l Two retention clips

The following subsections describes how to remove and install a microprocessor in either the primary or secondary microprocessor connector.

Removing a Microprocessor

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

Figure 6-6. Retention Clip

4. Remove the heat sink.

5. Remove the microprocessor from the socket by pulling the socket release lever straight up until the processor is released, and then lift the processor out of the socket. See Figure 6-7.

If you are installing a new microprocessor, leave the release lever up so that the socket is ready for the new microprocessor.

Figure 6-7. Removing the Microprocessor

NOTICE: The second microprocessor must be of the same type and speed as the first microprocessor.

CAUTION: Ensure that you install only microprocessors purchased from Dell and intended for this system. Using a different microprocessor could cause data loss, system damage, or personal injury.

CAUTION: Before you perform this procedure, you must turn off the system and disconnect it from its electrical outlet. For more information, see "Safety FirstFor You and Your System" in "Troubleshooting Your System."

NOTICE: Never remove the heat sink from a microprocessor unless you intend to remove the microprocessor. The heat sink is necessary to maintain proper thermal conditions.

CAUTION: The microprocessor chip and heat sink can become extremely hot. Be sure that the microprocessor has had sufficient time to cool before handling.

NOTICE: Be careful not to bend any of the pins when removing the microprocessor. Bending the pins can permanently damage the microprocessor.

Installing a Microprocessor

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

2. Open the system covers. See "Opening the System Covers" in "Troubleshooting Your System."

3. Unpack the new microprocessor.

If any of the pins on the microprocessor appear bent, see "Getting Help."

b. With the pin-1 corners of the processor and socket aligned, set the processor lightly in the socket and make sure that all pins are matched with the correct holes in the socket.

Because the system uses a ZIF microprocessor socket, you do not need to use force (which could bend the pins if the microprocessor is misaligned). When the microprocessor is positioned correctly, it should drop down into the socket with minimal pressure.

c. When the processor is fully seated in the socket, rotate the socket release lever back down until it snaps into place, securing the processor.

7. Place the new heat sink on top of the microprocessor. See Figure 6-10.

8. Replace the two retention clips:

a. Orient the retention clips. The clips are designed in pairs so that each clip fits only one end of the socket; when installed, the clips face opposite ways.

l For processor 1, the outer retention clip's release tab faces the back of the system; the inner retention clip faces the opposite way.

l For processor 2, the outer retention clip's release tab faces the front of the system; the inner retention clip faces the opposite way.

b. Hook the end of the clip that is opposite the release tab over the retaining tab on the edge of the socket.

c. Press the clip down so that the hole in the middle of the clip engages the tab in the side of the socket.

d. Continue pressing down on the release tab while pressing in on the free end of the clip until the end of the clip snaps over the tab on the corner of the socket. See Figure 6-10.

Ensure that you do not damage the ribbon cable at the back of the drive.

Figure 7-5. Installing a Diskette Drive

7. Connect the other end of the ribbon cable to the diskette drive connector on the SCSI backplane. See Figure A-4.

8. Close the system covers. See "Closing the System Covers" in "Troubleshooting Your System."

9. Replace the front bezel, if it was removed in step 2. See "Removing and Replacing the Optional Front Bezel" in "Troubleshooting Your System."

10. Reconnect the system and peripherals to their electrical outlets.

Connecting External SCSI Hard Drives

Follow these general guidelines when connecting external SCSI hard drives to the external SCSI connector on the system's back panel or to a SCSI controller card.

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

2. If you are installing a SCSI controller card, install the card now. See "Installing Expansion Cards" in "Installing System Options."

3. Connect the external SCSI devices to the external SCSI connector on the system's back panel.

CAUTION: Before you perform this procedure, you must turn off the system and disconnect it from its power source. For more information, see "Safety FirstFor You and Your System" in "Troubleshooting Your System."

CAUTION: Only trained service technicians are authorized to remove the system cover and access any of the components inside the system. See your System Information Guide for complete information about safety precautions, working inside the computer, and protecting against electrostatic discharge.

If you are attaching multiple external SCSI devices, daisy-chain the devices using the cables shipped with each device.

4. Reconnect the system to an electrical outlet and turn it on.

5. Connect the external device(s) to electrical outlet(s) and turn them on.

6. Install any required SCSI device drivers. See "Installing and Configuring SCSI Drivers" in the User's Guide.

7. Test the SCSI devices.

Connecting an External SCSI Tape Drive

This subsection describes how to configure and install an external SCSI tape drive with an add-in PCI controller card.

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

2. Ground yourself by touching an unpainted metal surface on the back of the system, unpack the drive, and compare the jumper and switch settings with those in the documentation that came with the drive.

3. Unpack the tape drive and controller card and configure the tape drive according to the documentation that came with the tape drive, based on the following guidelines:

a. Each device attached to a SCSI host adapter must have a unique SCSI ID number. (Narrow SCSI devices use IDs 0 to 7; wide SCSI devices use IDs from 0 to 15).

A SCSI tape drive is typically configured as SCSI ID 6.

b. SCSI logic requires that the two devices at opposite ends of a SCSI chain be terminated and that all devices in between be unterminated. Therefore, you enable the tape drive's termination if it is the last device in a chain of devices (or sole device) connected to the SCSI controller.

4. Install the controller card in an expansion slot. See "Installing Expansion Cards" in "Installing System Options."

5. Connect the tape drive's interface/DC power cable to the connector on the controller card supplied with the tape drive.

6. Reconnect the system and peripherals to their electrical outlets, and turn them on.

7. Perform a tape backup and verification test with the drive as instructed in the software documentation that came with the drive.

Configuring the Boot Device

If you plan to boot the system from a hard drive, the drive must be attached to the primary (or boot) controller. The device that the system boots from is determined by the boot order specified in the System Setup program.

The System Setup program provides options that the system uses to scan for installed boot devices. See your system's User's Guide for information about the System Setup program.

Back to Contents Page

NOTE: The integrated SCSI controller does not support mixed mode (one channel SCSI and one channel RAID). For this reason, in a system with RAID, Dell does not support an external tape drive connected to the external SCSI controller.

CAUTION: Only trained service technicians are authorized to remove the system cover and access any of the components inside the system. See your System Information Guide for complete information about safety precautions, working inside the computer, and protecting against electrostatic discharge.

NOTE: There is no requirement that SCSI ID numbers be assigned sequentially or that devices be attached to the cable in order by ID number.
