Jumpers and Connectors Dell PowerEdge 1500SC 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 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 jumper blocks on the system board. 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 function of these jumpers.

Figure A-2. System Board Jumpers  

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

WARNING: Before you perform this procedure, you must turn off the system and disconnect it from its power source. For more information, 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 document.

System-Board Connectors

See Figure 6-1 and Table 6-1 for the location and description of system board connectors.

SCSI Backplane Board Connectors

Figure A-3 shows the location of the connectors on the back of the SCSI backplane board.

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

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.  Remove the system cover (see "Removing the Side 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.  Replace the system cover, and then 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 install the jumper plug.

5.  Repeat step 1.

6.  Install the jumper plug on the PASSWD jumper.

7.  Replace the system cover, and then reconnect the system and peripherals to their electrical outlets and turn them on.

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

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

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

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.

l SCSI hard drive indicator codes

l Power supply indicator codes

The system indicators and the front and back panel features are illustrated in this section. This section also describes each type of message and lists the possible causes and actions you can take to resolve any problems indicated by a message. To determine what type of message you have received, read the following sections.

Bezel Indicators

When the bezel is in place on the system, it has two indicators (see Figure 2-1). The power indicator lights green when the system is operating correctly. The system alert indicator lights amber when the system needs attention.

Figure 2-1. Bezel Indicators  

Front-Panel Indicators and Features

Indicators on the front of the system are located on the power supplies, hard drives, and the control panel. The CD and diskette drives have green activity indicators.

Figure 2-2. Front-Panel Features  

Back-Panel Features

Figure 2-3 shows the back-panel features of the system.

Figure 2-3. Back-Panel Features  

SCSI Hard Drive Indicator Codes

If you have an optional RAID controller installed, three indicators on each of the hard drive carriers provide information on the status of the SCSI hard drives (see Table 2-1). The SCSI backplane firmware controls the drive online and drive failure indicators.

Figure 2-4. Hard-Drive Indicators  

Table 2-1 lists the drive indicator patterns established by the SCSI backplane firmware. Different patterns are displayed as drive events occur in the system. For example, in the event of a hard drive failure, the "drive failed" pattern appears. After the drive is selected for removal, the "drive being prepared for removal" pattern appears, followed by the "drive ready for insertion or removal" pattern. After the replacement drive is installed, the "drive being prepared for operation" pattern appears, followed by the "drive online" pattern.

Power Supply Indicators

Your system has two power supply options. A single nonredundant power supply or up to two hot-pluggable redundant power supplies. The single nonredundant power supply does not have indicators. The hot-pluggable redundant power supply indicators are shown in Figure 2-5.

Warning Messages

A warning message alerts you to a possible problem and asks you to take corrective action before the system continues a task. For example, before you format a diskette, a message might warn you that you might lose all data on the diskette, as a way to protect against inadvertently erasing or writing over the data. These warning messages usually interrupt the procedure and require you to respond by typing y (yes) or n (no).

Diagnostics Messages

When you run a test group or subtest in system diagnostics, an error message may result. These particular error messages are not covered in this section. Record the message on a copy of the Diagnostics Checklist (see "Getting Help"), and then follow the instructions in that section for obtaining technical assistance.

Alert Log Messages From the System Management Software

The optional system management software generates alert messages for your system. For example, the server agent generates messages that appear in the SNMP trap log file.

  Installing and Configuring Software

  Using Software

Because most systems have several application programs installed in addition to the operating system, isolating a software problem can be confusing. Software errors can also appear to be hardware malfunctions at first.

Software problems can result from the following circumstances:

l Improper installation or configuration of a program

l Input errors

l Device drivers that may conflict with certain application programs

l Interrupt conflicts between devices

You can confirm that a system problem is caused by software by running system diagnostics. If all tests in the test group are completed successfully, the problem is most likely caused by software.

This section provides some general guidelines for analyzing software problems. For detailed troubleshooting information on a particular program, see the documentation that accompanied the software or consult the support service for the software.

Installing and Configuring Software

Use virus-scanning software to check newly acquired programs and files for viruses before installing the programs on the system's hard drive. Viruses can quickly use all available system memory, damage and/or destroy data stored on the hard drive, and permanently affect the performance of the programs they infect. Several commercial virus-scanning programs are available for purchase.

Before installing a program, read its documentation to learn how the program works, what hardware it requires, and what its defaults are. A program usually includes installation instructions in its accompanying documentation and a software installation routine.

The software installation routine assists users in transferring the appropriate program files to the system's hard drive. Installation instructions may provide details about how to configure the operating system to successfully run the program. Always read the installation instructions before running a program's installation routine.

When you run the installation routine, be prepared to respond to prompts for information about how the system's operating system is configured, what type of system you have, and what peripherals are connected to the system.

Using Software

The following subsections discuss errors that can occur as a result of software operation or configuration.

Error Messages

Error messages can be produced by an application program, the operating system, or the system. "Indicators, Messages, and Codes" discusses the error messages that are generated by the system. If you receive an error message that is not listed in "Indicators, Messages, and Codes," check the operating system or application program documentation.

Input Errors

If a specific key or set of keys is pressed at the wrong time, a program may give you unexpected results. See the documentation that came with the application program to make sure that the values or characters you are entering are valid.

Make sure that the operating environment is set up to accommodate the programs you use. Keep in mind that whenever you change the parameters of the system's operating environment, you may affect the successful operation of the programs. Sometimes, after modifying the operating environment, you may need to reinstall a program that no longer runs properly.

Program Conflicts

Some programs may leave portions of their setup information behind, even though you have exited from them. As a result, other programs cannot run. Rebooting the system can confirm whether these programs are the cause of the problem.

Device drivers, which are programs that use specialized subroutines, can cause problems with the system. For example, a variation in the way the data is sent to the monitor may require a special screen driver program that expects a certain kind of video mode or monitor. In such cases, you may have to develop an alternate method of running that particular programby creating a start-up file made especially for that program, for example. Call the support service for the software you are using to help you with this problem.

Avoiding Interrupt Assignment Conflicts

Problems can arise if two devices attempt to use the same IRQ line. To avoid this type of conflict, check the documentation for the IRQ line's default for each installed expansion card. Then consult Table 3-1 to configure the card for one of the available IRQ lines.

Back to Contents Page

Table 3-1. IRQ Line Assignment Defaults

IRQ Line Used By/Available

IRQ0 Used by the system timer

IRQ1 Used by the keyboard controller

IRQ2 Used by interrupt controller 1 to enable IRQ8 through IRQ15

Unlike many diagnostic programs, system diagnostics helps you check the system's hardware without any additional equipment and without destroying any data. By using the diagnostics, you can have confidence in the system's operation. If you find a problem that you cannot solve by yourself, the diagnostic tests can provide you with important information you will need when talking to a technical assistance representative.

Features of the System Diagnostics

System diagnostics provides a series of menus and options from which you choose particular device groups or devices. You can also control the sequence in which the tests are run. The diagnostic menus also have these helpful features:

l Options that let you run tests individually or collectively

l An option that allows you to choose the number of times a test is repeated

l The ability to display or print test results or to save them in a file

l Options to temporarily suspend testing if an error is detected or to terminate testing when an adjustable error limit is reached

l Help messages that briefly describe each test and its parameters

l Status messages that inform you whether device group or device tests are completed successfully

l Error messages that appear if any problems are detected

When to Use System Diagnostics

Whenever a major component or device in the system does not function properly, you may have a component failure. As long as the microprocessor and the input and output components of the system (the monitor, keyboard, and diskette drive) are working, you can use system diagnostics. If you know what component(s) you need to test, simply select the appropriate diagnostic device group(s) or subtest(s). If you are unsure about the scope of the problem, read the rest of the information in this section.

Starting System Diagnostics

You can run system diagnostics from either the utility partition on your hard drive or from a set of diskettes that you create from the Dell OpenManage Server Assistant CD.

To run the diagnostics from the utility partition, perform the following steps:

1.  Start the utility partition by pressing during POST.

2.  From the utility partition's main menu, select the Run System Diagnostics option from Run System Utilities.

Inside the System

In Figure 5-6, the system cover and front bezel are removed to provide an interior view of the system.

Figure 5-6. Inside the System  

The system board can accommodate up to six PCI expansion cards (four cards at 64-bit/66 MHz and two cards at 32-bit/33 MHz). The system memory is contained in four memory module slots that must be populated with at least two memory modules. The peripheral bay provides space for a 3.5-inch diskette drive and a CD drive and one other device.

The hard drive bays provide space for up to six 1-inch SCSI hard drives. These hard drives are connected to a SCSI host adapter on the system board or on an expansion card, via the SCSI backplane board.

In a single nonredundant power supply system, the power supply will connect directly to and provide power to the system board, SCSI backplane, and internal peripherals. In a redundant hot-pluggable power-supply system, the dual hot-pluggable power supplies connect directly to the power-supply distribution board (PSDB) which then provides power to the system board, SCSI backplane, and internal peripherals.

For non-SCSI drives such as the diskette drive and CD drive, an interface cable connects the devices to the system board. For SCSI devices, interface cables connect externally accessible SCSI devices and the SCSI backplane board to a SCSI host adapter either on the system board or on an expansion card. (For more information, see "Installing Drives.")

During an installation or troubleshooting procedure, you may be required to change a jumper. For information on the system board jumpers, see "Jumpers and Connectors."

Responding to a System Management Alert Message

Configuring the Boot Device

The external drive bays of your system hold up to three user-accessible, half-height 5.25-inch devices (typically CD or tape drives). A CD drive is standard in the first external drive bay, while two additional devices of your choice can be installed in the next two external drive bays. A fourth drive bay accommodates a standard 3.5-inch diskette drive, which is controlled by the diskette drive controller on the system board.

The hard drive bays provide space for up to six 1-inch hard drives. These hard drives are hot-pluggable.

Installing Devices in the External Drive Bay

A CD drive is standard in the first external drive bay, while two additional devices of your choice can be installed in the next two external drive bays.

Before You Begin

This section describes how to install the following options:

l Drives that use the computer's integrated diskette drive controller

l Drives that use the computer's integrated Ultra/Narrow SCSI controller

l Tape drives that use a controller card

To remove or install drives in the external bays, you must remove the system covers. See "Removing and Replacing the System Covers" in "Troubleshooting Your System."

Removing and Replacing Front-Panel Inserts

To protect the inside of the computer from foreign particles, a plastic insert covers each empty external drive bay. Additionally, each empty external drive bay is covered by a metal insert to maintain the necessary electromagnetic interference (EMI) shielding for the chassis. Before you install a drive in an empty bay, you must first remove the plastic and metal inserts. Whenever you remove a drive, be sure to replace the metal insert on the chassis and then replace the plastic insert in the front bezel to cover the empty bay.

Removing a Plastic Insert

1. Remove the front bezel (see "Removing the Front Bezel" in "Troubleshooting Your System").

2. Facing the inside of the front bezel, press against the center of the insert with your thumbs to loosen the tabs on the sides of the insert.

3. Pull the insert out of the bezel.

Removing a Metal Insert

1. Remove the front bezel (see "Removing the Front Bezel" in "Troubleshooting Your System").

2. Use your thumb to press in the tab on the right edge of the metal insert to release the insert.

3. Pivot the insert away from the chassis and disengage the tab on the insert's left edge.

Connecting the Drive

This section describes the interface cables and power cables used with the drives in your system.

Interface Cables

Most interface connectors are keyed for correct insertion; that is, a notch or a raised tab on one connector matches a tab or a notch on the other connector. Keying ensures that the pin-1 wire in the cable goes to the pin-1 ends of the connectors on both ends.

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

DC Power Cables

Each drive in the external drive bays must connect to a 4-wire DC power cable from the system power supply. The connectors on these cables are labeled "P3," "P4," "P5," and "P6." Connectors P3, P4, and P5 are used for 5.25-inch devices; connector P6 is used for the 3.5-inch diskette drive.

SCSI Configuration Information

Although SCSI devices are installed essentially the same way as other devices, their configuration requirements are different. To configure SCSI devices installed in the external bays, follow the guidelines in the following subsections.

SCSI ID Numbers

Each device attached to the SCSI host adapter must have a unique SCSI ID number from 0 to 7.

When SCSI devices are shipped, the default SCSI ID numbers are assigned as follows:

l The integrated SCSI host adapter is configured through the BIOS as SCSI ID 7.

l A SCSI tape drive is configured as SCSI ID 6 (the default ID number for a tape drive).

Device Termination

SCSI logic requires that the two devices at opposite ends of the SCSI chain be terminated and that all devices in between be unterminated. The SCSI cable included in your system has an active terminator installed at the end of the cable. Disable the termination on all SCSI devices you attach to this cable.

Installing SCSI Hard Drives

This subsection describes how to install and configure SCSI hard drives in the system's internal hard drive bays, and how to upgrade the system by installing a host adapter expansion card.

The internal hard drive bays provide space for up to six 1-inch hard drives. These drives connect to a SCSI backplane board. A SCSI cable connects the SCSI backplane board to the SCSI host adapter connector on the system board or to an optional SCSI host adapter card.

Before You Begin

Before attempting to remove or install a drive while the system is running, see the documentation for the host adapter card to ensure that the card is configured correctly to support hot-pluggable drive removal and insertion.

SCSI hard drives are supplied in special drive carriers that fit in the hard drive bays.

See the following guidelines when you configure the SCSI drive:

l Disable termination on the drive. The SCSI backplane board provides termination for the SCSI bus.

l Set the SCSI ID on all drives to 0. All SCSI ID numbers for the drives are set by the SCSI backplane board.

l Configure the drive so that the drive motor waits for a Start Unit command from the SCSI host adapter before spinning.

When you format a high-capacity SCSI hard drive, allow enough time for the formatting to be completed. Long format times for these drives are normal. A 9 GB hard drive, for example, can take up to 2.5 hours to format.

Installing a SCSI Hard Drive

1. If the system does not have a RAID controller installed, shut down the system.

2. Remove the front bezel (see "Removing the Front Bezel" in "Troubleshooting Your System").

3. Open the hard drive carrier handle (see Figure 7-1).

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.

NOTE: We recommend that you use only drives that has been tested and approved for use with the SCSI backplane board.

NOTICE: Do not turn off or reboot your system while the drive is being formatted. Doing so can cause a drive failure.

NOTICE: Hot-plug drive installation is not supported for systems without a host adapter expansion card.

Figure 7-1. Installing a SCSI Hard Drive

4. Insert the hard drive into the drive bay (see Figure 7-1).

5. Close the hard drive carrier handle to lock the drive in place.

6. Replace the front bezel (see "Replacing the Front Bezel" in "Troubleshooting Your System").

7. Install any required SCSI device drivers (see "Installing and Configuring SCSI Drivers," in the User's Guide for information).

8. If the hard drive is a new drive, run the SCSI Controllers test in system diagnostics.

Removing a SCSI Hard Drive

1. If the system does not have a RAID controller installed, shut down the system.

2. For systems with host adapter expansion cards, power down the hard drive bay and wait until the SCSI hard drive indicator codes on the drive carrier signal that the drive can be removed safely.

If the drive has been online, the drive status indicators will flash sequentially as the drive is powered down. When all indicators are turned off, the drive is ready for removal.

3. Remove the front bezel (see "Removing the Front Bezel" in "Troubleshooting Your System").

4. Open the hard drive carrier handle to release the carrier.

5. Slide the carrier toward you until it is free of the drive bay.

6. Replace the front bezel (see "Replacing the Front Bezel" in "Troubleshooting Your System").

Installing a 5.25-Inch Device

1. Prepare the drive for installation.

Ground yourself by touching an unpainted metal surface on the back of the computer, unpack the drive, and compare the jumper and switch settings with those in the drive documentation. (See "SCSI Configuration Information," for information on setting the drive's SCSI ID number and enabling termination [if required].) Change any settings necessary for this system's configuration.

If the drive does not already have drive rails attached, attach a drive rail to each side of the drive and secure each drive rail to the drive with a screw in each of the lower slotted screw holes on the drive rail.

2. Remove the front bezel (see "Removing the Front Bezel" in "Troubleshooting Your System").

3. Remove the right-side cover (see "Removing the Side Covers" in "Troubleshooting Your System").

4. If other installed drives are in the way, temporarily move them out of the way.
