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 Connector

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.

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.

Warning Messages

A warning message alerts you to a possible problem and prompts you to respond before the system continues a task. For example, before you format a diskette, a message will warn you that you may lose all data on the diskette. Warning messages usually interrupt the task and require you to respond by typing y (yes) or n (no).

Diagnostics Messages

When you run system diagnostics, an error message may result. Diagnostic error messages are not covered in this section. Record the message on a copy of the Diagnostics Checklist in "Getting Help," and then follow the instructions in that section for obtaining technical assistance.

Alert Messages

Systems management software generates alert messages for your system. Alert messages include information, status, warning, and failure messages for drive, temperature, fan, and power conditions. For more information, see the systems management software documentation.

Back to Contents Page

NOTE: Warning messages are generated by either the application or the operating system. For more information, see "Finding Software Solutions" and the documentation that accompanied the operating system or application.

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.

5. Repeat step 3 and step 4 to remove the other securing clip.

Figure 6-9. Installing and Removing the Securing Clip

CAUTION: See your System Information Guide for complete information about safety precautions, working inside the computer, and protecting against electrostatic discharge.

CAUTION: See your System Information Guide for complete information about safety precautions, working inside the computer, and protecting against electrostatic discharge.

NOTICE: The processor and heat sink can become extremely hot. Be sure the processor has had sufficient time to cool before handling.

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

6. Remove the heat sink.

a. Gently rotate the heat sink side-to-side before lifting the heat sink from the processor.

b. If the processor is removed from the socket with the heat sink, twist or slide the processor off of the heat sink. Do not pry the processor off of the heat sink.

c. Set the heat sink upside down so as not to contaminate the thermal grease.

7. Pull the socket-release lever straight up until the processor is released from the socket. See Figure 6-10.

8. Lift the processor out of the socket and leave the release lever up so that the socket is ready for the new processor.

9. Unpack the new processor.

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

10. Align the pin-1 corner of the processor with the pin-1 corner of the ZIF socket. See Figure 6-10.

Identify the pin-1 corner of the processor by locating the tiny gold triangle on one corner of the processor. Place this corner in the same corner of the ZIF socket identified by a corresponding triangle.

11. Install the processor in the socket.

Figure 6-10. Installing and Removing the Processor in the Socket

NOTE: When removing the heat sink, the possibility exists that the processor might adhere to the heat sink and be removed from the socket. It is recommended that you remove the heat sink while the processor is still warm.

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

NOTE: Identifying the pin-1 corners is critical to positioning the processor correctly.

If the release lever on the processor socket is not positioned all the way up, move it to that position.

With the pin-1 corners of the processor and socket aligned, set the processor lightly in the socket, making sure all pins are matched with the correct holes in the socket. Because the system uses a ZIF processor socket, do not use force, which could bend the pins if the processor is misaligned. When the processor is positioned correctly, it drops down into the socket with minimal pressure.

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

12. Install the heat sink.

a. Using a clean lint-free cloth, remove the existing thermal grease from the heat sink.

b. Apply thermal grease evenly to the top of the processor.

c. Align the holes on both sides of the heat sink with the heat-sink posts on the system chassis. See Figure 6-9.

13. Orient the securing clips so that the rubber-coated tabs are toward the back of the chassis.

14. Lower the end opposite of the rubber-coated tab of each securing clip over the heat-sink post, and then slide the securing clip toward the heat-sink post until they snap onto the post. See Figure 6-9.

15. While holding down the rubber-coated tab with one hand, push the latch on the securing clip toward the heat-sink post until it locks the clip onto the post.

16. Repeat step 14 and step 15 for the other securing clip.

17. Install the cooling shroud. See "Installing the Cooling Shroud."

18. Close the system. See "Closing the System" in "Troubleshooting Your System."

As the system boots, it detects the presence of the new processor and automatically changes the system configuration information in the System Setup program.

19. Press to enter the System Setup program, and check that the processor information matches the new system configuration.

See your User's Guide for instructions about using the System Setup program.

20. Run the system diagnostics to verify that the new processor operates correctly.

See "Running the System Diagnostics" for information about running the diagnostics and troubleshooting processor problems.

NOTICE: Positioning the processor incorrectly can permanently damage the processor and the system when you turn it on. When placing the processor in the socket, be sure that all of the pins on the processor enter the corresponding holes. Be careful not to bend the pins.

NOTE: Use the heat sink that you removed in step 6.

NOTE: If the securing clips are installed so that the rubber-coated tabs are toward the front of the system, the cooling shroud cannot be installed correctly.

SCSI Configuration Information

Although SCSI drives are installed in essentially the same way as other drives, their configuration requirements are different. To install and configure a SCSI drive, follow the guidelines in the following subsections.

SCSI Interface Cables

SCSI interface connectors are keyed for correct insertion. Keying ensures that the pin-1 wire in the cable connects to pin 1 in the connectors on both ends.

CAUTION: See your System Information Guide for complete information about safety precautions, working inside the computer, and protecting against electrostatic discharge.

When you disconnect an interface cable, take care to grasp the cable connector, rather than the cable itself, to avoid stress on the cable.

SCSI ID Numbers

Each drive attached to a SCSI controller must have a unique SCSI ID number from 0 to 15.

l The SCSI hard drive from which the system boots is configured as SCSI ID 0.

l If you install optional SCSI drives or change your SCSI configuration, see the documentation for each SCSI drive for information on setting the appropriate SCSI ID number.

Device Termination

SCSI logic requires that termination be enabled for the two drives at opposite ends of the SCSI chain and disabled for all drives in between. For internal SCSI drives, termination is configured automatically. See the documentation provided with any optional SCSI drive you purchase for information on disabling termination.

Configuring the Boot Drive

The drive or device from which the system boots is determined by the boot order specified in the System Setup program. See "Using the System Setup Program" in your User's Guide. To boot the system from a hard drive or drive array, the drive(s) must be connected to the appropriate controller:

l To boot from a single SATA hard drive, the master drive (drive 0) must be connected to the SATA_PORT_0 connector on the system board. To identify system board connectors, see Figure A-3.

l To boot from a single SCSI hard drive, the drive must be connected to the SCSI controller card. See the documentation that accompanied the controller card.

l To boot from a SCSI RAID array, the drive must be connected to the RAID controller card. See the documentation that accompanied the controller card.

Hard Drives

Your system contains up to two non-hot-pluggable SATA or SCSI hard drives. If your system contains SCSI hard drives, they must be connected to a SCSI controller board. The cables for hard drive 1 are routed in the cable tray that is part of the fan assembly.

The procedures for removing and installing SATA or SCSI hard drives are the same.

Removing a Hard Drive

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

2. If applicable, remove the optional CD drive or optional diskette drive.

Remove the CD drive if you are removing hard drive 0. See "Removing the Optional CD Drive."

Remove the optional diskette drive if you are removing hard drive 1. See "Removing the Optional Diskette Drive."

3. Disconnect the power and interface cables from the hard drive.

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

CAUTION: See your System Information Guide for complete information about safety precautions, working inside the computer, and protecting against electrostatic discharge.

The interface cables for SATA hard drives are connected to the system board. See Figure A-3 for the location of the system board connectors.

The interface cables for SCSI hard drives are connected to a controller card.

4. Loosen the captive screw that secures the hard-drive carrier to the chassis. See Figure 7-3.
