System Overview

Dell PowerEdge 6300 systems are feature-rich, enterprise-class server systems that use Intel Pentium II Xeon microprocessor(s) with MMX technology and incorporate a high-performance PCI local bus.

The PowerEdge 6300 systems have been designed for better serviceability and increased reliability. The sliding system board tray allows easy access to the system board for performing processor and memory upgrades. The Dell- designed SCSI backplane board and hard-disk drive carriers eliminate the extensive cabling and drive configuration usually required for a SCSI sub- system. The plastic drive rails attached to devices mounted in the external drive bays allow you to remove these devices without removing a single screw. The systems can be used either freestanding or rack-mounted.

A PowerEdge 6300 system can contain up to four Pentium II Xeon micropro- cessors. Each processor is housed in a single-edge contact (SEC) cartridge/ heat sink assembly mounted in a guide bracket on the system board, allowing for greater heat dissipation. The processor has an internal operating frequency of 400 MHz (or a higher speed when available) and an external operating fre- quency of 100 MHz. Contact Dell for information about Dell-supported microprocessor upgrades.

System Features In addition to the standard features found in a traditional personal computer, Dell PowerEdge 6300 systems include the following new and/or advanced features:

One to four Intel Pentium II Xeon microprocessors with an internal operat- ing frequency of 400 MHz (and higher speeds when available) and an external bus speed of 100 MHz.

Support for symmetric multiprocessing (SMP) when two or more micro- processors are installed.

NOTE: Additional microprocessors must have the same internal operating frequency as the initial microprocessors. Not all versions of the Pentium II microprocessor will work properly as additional microprocessors in this system; the upgrade kit from Dell contains the correct version for this system.

A secondary (L2) cache of 512 KB, 1 MB, or 2 MB of SRAM is included within the SEC cartridge that contains the microprocessor.

1-2 Dell PowerEdge 6300 Systems Service Manual

System Overview 1-7

System Memory System memory resides on a memory module card and consists of a mini- mum of 128 MB of 72-bit buffered EDO memory. Memory can be expanded up to 4 GB by installing combinations of 32-, 128-, and 256-MB buffered EDO DIMMs on the memory module.

NOTE: DIMMs must be rated at 50 or 60 ns. With a mixture of 50- and 60-ns DIMMs, system memory will run at 60 ns.

The memory module provides 16 168-pin DIMM sockets divided into four banks, each consisting of four sockets labeled DIMM A through DIMM D (see Figure 1-6). Memory upgrade guidelines are as follows:

DIMMs must be installed one bank (four DIMMs) at a time, starting with bank 1 and working toward bank 4. There should be no open banks between populated banks.

Within a bank, install DIMMs in the following order: DIMM A, DIMM B, DIMM C, and DIMM D.

DIMM sizes cannot be mixed within a memory bank. However, one mem- ory bank can hold different-size DIMMs from another memory bank.

Of the DIMMs to be installed in the system, install the size you have the most of in the lowest-numbered bank(s), the less numerous size in the next banks, and least numerous size in the highest-numbered banks being used. For example, when installing four 256-MB DIMMs, eight 128-MB DIMMs, and four 32-MB DIMMs, install the 128-MB DIMMs in banks 1 and 2. The 256- and 32-MB DIMMs can be installed in banks 3 and 4; it does not matter which bank holds which size.

See DIMMs in Chapter 4 of this document for information on removing and replacing DIMMs.

PCI Expansion Subsystem The Resource Configuration Utility (RCU) included with the system automati- cally configures installed PCI expansion cards. For more information on the RCU, see Chapter 5, Using the Resource Configuration Utility, in the Dell PowerEdge 6300 Systems Users Guide.

The seven expansion-card slots include four 64-bit and three 32-bit PCI expan- sion-card connectors located on the system board (see Figure 1-13). The 64-bit slots support both 32- and 64-bit cards.

Video Controller The video subsystem is built into the system board and consists of a PCI VGA- compatible video subsystem with an ATI 3D RAGE PRO SVGA video controller. The video subsystem contains 2 MB of SGRAM video memory, which is not upgradable. Maximum noninterlaced resolutions are 640 x 480 (16.7 million colors), 800 x 600 (16.7 million colors), and 1024 x 768 (256 colors).

Integrated SCSI Controllers Two integrated Adaptec AIC-7890 Ultra2/LVD SCSI host adapters support up to six 1- or 1.6-inch internal SCSI hard-disk drives through a 68-pin connector on the system board for a SCSI backplane board. The SCSI backplane board auto- matically configures SCSI ID numbers and SCSI termination on individual hard- disk drives, greatly simplifying drive installation. The integrated SCSI controller resides on the PCI local bus for optimum performance.

An integrated Adaptec AIC-7860 Ultra/Narrow SCSI host adapter attached to the PCI bus supports up to three SCSI devices in the external drive bays through a 50-pin connector on the system board.

SCSI Hard-Disk Drives Dell PowerEdge 6300 systems include a SCSI backplane board, which greatly simplifies cabling and configuration for SCSI hard-disk drives. SCSI ID and ter- mination for SCSI hard-disk drives are both configured by the SCSI backplane board, rather than on individual drives. SCSI hard-disk drives are supplied by Dell in special drive carriers that fit in the internal drive bays.

NOTE: For maximum performance, install Ultra2/LVD drives exclusively. Although you can install a mixture of Ultra2/LVD and Ultra hard-disk drives, they will operate at the slower Ultra transfer rate.

System Overview 1-9

SCSI Configuration Guidelines SCSI hard-disk drives must be configured as follows:

Disable termination on the drive. The SCSI backplane board provides termi- nation for the SCSI bus.

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

Configure the drive so that the drive motor waits for a start unit command from the SCSI host adapter before spinning.

SCSI devices in the external drive bays are controlled by the Ultra/Narrow SCSI controller on the system board. 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 Ultra/Narrow SCSI host adapter must have a unique SCSI ID number from 0 to 7.

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

The onboard Ultra/Narrow SCSI host adapter is configured through the BIOS as SCSI ID 7.

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

A SCSI CD-ROM drive is usually configured as SCSI ID 5.

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.

Device Termination All Dell PowerEdge 6300 systems have an active terminator installed at the end of the SCSI cable. All of the devices attached to the SCSI cable should have their termination disabled.

PSPB and System Power Supplies The Dell PowerEdge 6300 includes a PSPB and three 320-W redundant sys- tem power supplies.

System Power Supplies The system power supplies are stacked at the rear of the chassis and can slide in and out of the unit. When fully installed, a power supply automatically mates with a power harness attached to the back plate of the power supply cage. The power harness connects the power supply to the PSPB.

1-10 Dell PowerEdge 6300 Systems Service Manual

The power supplies can operate from an AC power source of 115 VAC at 60 Hz or 230 VAC at 50 Hz. They provide the DC operating voltages and currents listed in Table 1-1.

NOTE: The power supplies produce DC voltages only under their loaded condi- tion. Therefore, when you measure these voltages, the DC power connectors must be mated to their PSPB harnesses at the bulkhead, and the harnesses must be connected to their corresponding power input connectors on the PSPB. The PSPB in turn must be connected as appropriate to the system board, SCSI backplane board, or external drive bay.

.

PSPB The PSPB multiplexes input from the power supplies to supply redundant power to the system board, SCSI backplane, and external drive bays. Through embedded server management (ESM), the PSPB can also be used to perform such tasks as detecting the presence of one to three power supplies; monitor- ing voltage and current outputs from the power supplies, voltage going to the system board, and fan RPMs; and supporting the SMB_ALERT protocol used by the server management bus.

The PSPB connects to the power supplies through short harnesses that attach to the back of the power supply cages. The PSPB is attached to the side wall of the computer behind the external drive cage and is oriented in parallel with the system board. For information on removing and replacing the PSPB, see Power-Supply Paralleling Board in Chapter 4.

Figure 1-7 shows the PSPB power connector layout; Table 1-2 shows the cable connections made from the PSPB.

Pin Assignments for the PSPB Power Connectors The power-supply output voltages can be measured at the back (wire side) of the connectors without disconnecting them. In the following diagrams, volt- ages for the PSPB PWRx connectors are shown as measured at the system board; voltages for the PSPB FD connector are shown as measured at the PSPB; voltages for the PSPB HD_B/P connector are shown as measured at the SCSI backplane.

1 Pin 13 SYS_PS_ON# should measure between +4.75 and +5 .25 VDC except when the power button on the front panel is pressed, taking SYS_PS_ON# to its active-low state.

2 Pin 5 SYS_PWR_GOOD should measure between +4.75 and +5.25 VDC when the power supply is operating to indicate that all power-supply output voltages are within the ranges specified in Table 1-1.

CAUTION: Should you remove power from the SCSI backplane board (either by removing the power cable or during replacement of the system board battery), you may need to reflash your systems firmware.

The original firmware on the SCSI backplane is stored in EEPROM. However, if the SCSI backplane firmware is ever updated, the update is stored in volatile RAM. If power is removed from an updated back- plane board, the update will be lost and the board will revert to its original firmware in EEPROM.

If at system startup you receive the message Warning: Firmware is out-of-date, please update..., it is best to reflash all system firmware from your Dell Server Assistant CD.

Basic Troubleshooting

This chapter describes basic troubleshooting procedures that can help you diagnose a computer system problem. These procedures can often reveal the source of a problem or indicate the correct starting point for troubleshooting the system. For a brief explanation of how to load and start the system diag- nostics, see Running the Dell Diagnostics found later in this chapter. Dell recommends that you perform the following procedures in the order they are presented in this manual.

WARNING: The power supplies in this computer system produce high voltages and energy hazards, which can cause bodily harm. Only trained service technicians are authorized to remove the computer cover and access any of the components inside the computer.

Initial User Contact When you first contact a user who has a problem, ask the user to describe the problem and the conditions under which it occurs. A verbal description can often indicate the cause of a problem or indicate the appropriate troubleshoot- ing procedure to use. After the user describes the problem, follow these steps:

1. Ask the user to back up any data on the hard-disk drive if the systems condition permits.

Appendix C, Maintaining the System, in the Users Guide provides infor- mation about backing up data.

2. Ask the user to try to duplicate the problem by repeating the operations he or she was performing at the time the problem occurred.

Can the user duplicate the problem?

Yes. Proceed to step 3.

No. Proceed to the next section, External Visual Inspection.

2-2 Dell PowerEdge 6300 Systems Service Manual

3. Observe the user to determine if he or she is making an error, such as typing an incorrect key combination or entering a com- mand incorrectly.

Is the problem a result of user error?

Yes. Instruct the user in the proper procedure, or direct him or her to the appropriate user documentation for the correct procedure.

No. Proceed to the next section, External Visual Inspection.

External Visual Inspection The external visual inspection consists of a quick inspection of the exterior of the computer, the monitor, the keyboard, any peripherals, and cables. While performing the visual inspection, make any necessary corrections. To perform the external visual inspection, follow these steps:

1. Turn off the computer, the monitor, and all peripherals.

2. Verify that all power cables are properly connected to the com- puter, the monitor and peripherals, and their power sources.

3. Verify that the keyboard and mouse interface cables are firmly attached to the proper connectors on the back of the computer.

For a PS/2-compatible mouse, the keyboard and mouse interface cable connectors are identical except for their labels. If needed, see System Features in Chapter 1.

For a serial mouse, the mouse interface cable must be firmly attached to one of the serial port connectors, and its captive screws must be secure enough to ensure a firm connection.

4. If any network cables are present, verify that they are attached properly.

5. Verify that any devices attached to the serial and parallel port connectors are properly connected.

Each of the serial and parallel port interface cables must be firmly attached to an appropriate connector on the back of the computer as well as to the interface connector on the device. The captive screws that secure these connectors at each end of the interface cable must be secure enough to ensure a firm connection.

6. Verify that the video interface cable is firmly attached to the video connector on the back panel or to a video expansion card, and also to the connector on the back of the monitor.

For proper connection of the video monitor, see the documentation for the monitor.

Basic Troubleshooting 2-3

7. Inspect all external monitor controls for any obvious damage or improper settings.

For proper settings of the video monitor controls, see the documentation for the monitor.

8. Inspect the keyboard to ensure that no keys are sticking.

If one or more keys are sticking, it may be necessary to replace the keyboard.

9. Inspect the exterior of the computer, including all controls and indicators, and all user-accessible data storage devices for any signs of physical damage.

Does the inspection reveal any problems?

Yes. Proceed to the appropriate procedure in Chapter 4, Removing and Replacing Parts.

No. Proceed to the next section, Observing the Boot Routine.

Observing the Boot Routine After you have performed an external visual inspection as described in the pre- vious section, you should boot the system and, while the boot routine is running, observe the system for any indications of problems.

NOTES: Most of the steps in this procedure require observation of system functions and indications, some of which can occur simultaneously. It may be necessary to reboot the system several times in order to complete all of these steps.

To perform the following procedure, you need a Dell Diagnostics Diskette cre- ated from the Dell Server Assistant CD. If such a diskette is not available, you can create it as described in Create Diskettes in Chapter 2 of the Users Guide.

To observe problem indications during the boot routine, follow these steps:

1. If the system is off, turn on all peripherals and the computer. Insert the Dell Diagnostics Diskette into the diskette drive and reboot the system.

2. Check each power supply fan.

Does the fan run normally?

Yes. Proceed to step 3.

No. Troubleshoot the system power supply.

2-4 Dell PowerEdge 6300 Systems Service Manual

3. Watch the Num Lock, Caps Lock, and Scroll Lock indicators on the upper-right corner of the keyboard. After all three indicators flash momentarily, and following a long pause (approximately 30 seconds), the Num Lock indicator should light up and remain on (unless the Num Lock option is set to Off in the System Setup program).

Do these indicators flash on and off within approximately 10 seconds after the boot routine starts?

Yes. Proceed to step 4.

No. Troubleshoot the system power supplies. If the troubleshooting pro- cedure indicates that the system power supplies are operational, troubleshoot the memory.

4. During the boot routine, observe the system for any of the following:

Beep codes: A beep code is a series of beeps that indicates an error condition. If the system emits a beep code, see Table 3-1 later in this manual.

System error messages: These messages can indicate problems or provide status information. If a system error message is displayed, see Table 3-2 later in this manual.

Diskette-drive and hard-disk drive access indicators: These indicators light up in response to data being transferred to or from the drives. If either of these indicators fails to light up during the boot routine, trou- bleshoot the diskette drive or hard-disk drive subsystem, as appropriate.

5. Observe the monitor screen for the Diagnostics Menu.

Does the Diagnostics Menu appear?

Yes. See Running the Dell Diagnostics found later in this chapter.

No. Proceed to step 6.

6. Insert another copy of the Dell Diagnostics Diskette into the dis- kette drive, and reboot the system.

Does the Diagnostics Menu appear?

Yes. See Running the Dell Diagnostics found later in this chapter.

No. Proceed to the next section, Internal Visual Inspection.

Basic Troubleshooting 2-5

Internal Visual Inspection WARNING: The power supplies in this computer system produce high voltages and energy hazards, which can cause bodily harm. Only trained service technicians are authorized to remove the computer cover and access any of the components inside the computer.

CAUTION: Before you proceed with the internal visual inspection described in this section, ensure that the user has saved all open files and exited all open applications if possible.

A simple visual inspection of a computers interior hardware can often lead to the source of a problem, such as a loose expansion card, cable connector, or mounting screw. When you perform the visual inspection, refer to System Features in Chapter 1 to locate components in the inspection procedure.

To perform the internal visual inspection, follow these steps:

1. Turn off the system, including any attached peripherals, and dis- connect all the AC power cables from their power sources.

WARNING: Before beginning to work inside the computer, disconnect the power supply from the power source and the power supply cables from the power supply.

2. Remove the computers right side cover as described in Com- puter Cover in Chapter 4.

3. Verify that the chips, DIMMs, expansion cards, and SEC cartridge and heat sink assembly(ies) are fully seated in their sockets or connectors.

WARNING: The SEC cartridge and heat sink assembly can get extremely hot during system operations. Be sure that it has had sufficient time to cool before touching it.

WARNING: When handling the SEC cartridge and heat sink assembly, take care to avoid sharp edges on the heat sink.

To ensure that the chips are fully seated in their sockets, press firmly on the top of each chip.

To reseat the SEC cartridge and heat sink assembly(ies), remove and re- install it as described in SEC Cartridge and Heat Sink Assembly in Chapter 4.

To reseat a DIMM, remove it from its socket and reinstall it as described in DIMMs in Chapter 4.

If you need to reseat an expansion card, remove the card as described in Expansion Cards in Chapter 4, and then reinsert the card in its connec- tor, and carefully push it in until fully seated.

2-6 Dell PowerEdge 6300 Systems Service Manual

4. Verify that all jumpers are set correctly.

For information about these jumpers, see System Board Jumpers in Chapter 1.

5. Check all cable connectors inside the computer to verify that they are firmly attached to their appropriate connectors.

6. Reinstall the computer cover.

7. Reconnect the computer and any attached peripherals to their power sources, and turn them on.

Does the problem appear to be resolved?

Yes. No further steps are necessary.

No. Proceed to the next section, Eliminating Resource Conflicts, and to Getting Help found later in this chapter.

Eliminating Resource Conflicts Devices within the computer may require dedicated memory spaces, interrupt levels, or DMA channels, all of which must be allocated during installation of the devices. Because devices may be installed at different times, it is possible that the same resource is assigned to two or more devices.

Resource conflicts can result in disorderly or erratic system operation or sys- tem failure. If you suspect that resource conflicts might exist, check the system and reassign the resources as necessary.

For additional information, see Chapter 5, Using the Resource Configuration Utility, in the Users Guide or Interrupt Assignments and DMA Channel Assignments in Chapter 1 of this manual.

Running the Dell Diagnostics The Dell Diagnostics contains tests that aid in troubleshooting all major com- ponents of the computer system. To run the tests, you must first create a diagnostics diskette using the Dell Server Assistant CD as described in Create Diskettes in Chapter 2 of the Users Guide.

To start the Dell Diagnostics, turn off the system, insert a diagnostics diskette into drive A, and then turn on the system.

Starting the diagnostics causes the Dell logo screen to appear on the monitor screen, followed by a message indicating that the diagnostics is loading. Before the diagnostics loads, a program tests the portion of main memory (RAM) required for loading the diagnostics. If a RAM error is detected, a mes- sage appears on the screen telling you which DIMM has failed.

Basic Troubleshooting 2-7

If no errors are found in RAM, the diagnostics loads and the Diagnostics Menu appears. This menu lets you choose the following options or exit the Dell Diagnostics:

Run All Tests Runs all tests for a thorough check of the system

Run Quick Tests Runs selected tests from all test groups to quickly locate a failure or to indicate where further testing is needed to isolate a failure

Run Specific Tests Tests a particular area or subsystem

Getting Help If none of the troubleshooting procedures in this chapter or the tests in the Dell Diagnostics reveals the source of the problem or leads to the proper trou- bleshooting steps for determining the source of the problem, call Dell for technical assistance. For instructions, see the chapter titled, Getting Help, in the Installation and Troubleshooting Guide.

Codes and Messages

This chapter describes beep codes, system messages, alert messages from the Dell OpenManage HIP application, and SCSI hard-disk drive indicator codes that can occur during POST or during normal system operation. Tables 3-1 and 3-2 list faults that can cause a beep code or system message to occur and the probable causes of the fault in each case. Table 3-3 explains the hard-disk drive indicator patterns.

If a faulty system does not emit beep codes or display system messages to indicate a failure, you should use the Dell Diagnostics to run the appropriate tests to help isolate the source of the problem. See Chapter 5, Running the Dell Diagnostics, in the Installation and Troubleshooting Guide.

POST Beep Codes

If the monitor cannot display error messages during the POST, the system may emit a series of beeps that identifies the problem or that can help you identify a faulty component or assembly. Table 3-1 lists the beep codes that may be generated during the POST. Most beep codes indicate a fatal error that pre- vents the system from completing the boot routine until the indicated condition is corrected.

When the system emits a beep code, record the code and then find it in Table 3-1. If the table does not lead to the source of the problem, run the appropriate tests in the Dell Diagnostics to assist in troubleshooting the problem.

Power supply lost redun- dancy detected

The system has detected that one of the three power sup- plies has failed and thus lost power sup- ply redundancy. If a second power sup- ply fails, the system will be inoperable.

Check the power supply indicators for a power supply fail- ure. Check to make sure the latch switch on each power sup- ply is enabled. Check each connection to the power source. If a power supply fail- ure is confirmed, replace the failed power supply as soon as possible. (The systems default configuration is redundant power. Although it will run with only two func- tioning power sup- plies, redundancy will be lost.)

Power supply degraded redundancy detected

A power supply may be failing or a power utilization warning threshold has been exceeded. The sys- tem will function normally in this con- figuration and is still redundant.

Check the power supply indicators for a power supply fail- ure. Check to make sure the latch switch on each power sup- ply is enabled. Check each connec- tion to the power source. Check the power utilization warning thresholds to verify they are valid values.

Power supply detected a failure

The power supply sensor detected a failure in one of the power supplies. If possible, the power supply number is provided.

Check the power supply indicators for a power supply fail- ure. Check to make sure the latch switch on each power sup- ply is enabled. Check each connec- tion to the power source.

SCSI Hard-Disk Drive Indicator Codes Three indicator lights in each SCSI hard-disk drive carrier provide information on the status of the SCSI hard-disk drives (see Figure 3-1). The SCSI backplane firmware controls the drive online and drive failure indicators.

Figure 3-1. Hard-Disk Drive Indicators

Table 3-4 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-disk 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.

NOTE: If you do not have a Dell PowerEdge Expandable RAID Controller host adapter card installed, you will see only the drive online and drive bay empty indicator patterns.

Externally Accessible Drives The chassis provides three bays for 5.25-inch externally accessible drives and a bay dedicated to a 3.5-inch diskette drive.

Front-Panel Inserts

Figure 4-5. Front-Panel Inserts

To remove the front-panel insert that covers an unused bay (see Figure 4-5), first remove the front bezel. Then, facing the inside of the front bezel, press one of the securing tabs (located at each end of the bezel) while pressing against the center of the insert until it springs free from the bezel.

To replace a front-panel insert, from inside the chassis place the insert into the bay opening and press it into place until the tabs on each end of the insert snap into the latches on the inside of the bezel.

Close-Out Panels Metal close-out panels that fit into the drive-bay openings in the chassis pro- vide extra EMI shielding under the plastic front-panel inserts. The close-out panel for a 1.6-inch bay has a raised lip at the bottom that overlaps the top of a panel beneath it, if any. Because of the overlap, if two or more 1.6-inch close- out panels are installed, you must remove them from the top down. The close- out panel for the 1-inch diskette-drive bay (the top bay in either chassis orienta- tion) is narrower and has no overlap lip.

front-panel inserts

4-8 Dell PowerEdge 6300 Systems Service Manual

To remove a close-out panel, pry the bottom of the panel outward at the center until you can unhook a securing tab at one end and work out the other end.

When installing close-out panels, install 1.6-inch panels from the bottom up. Make sure the overlap lip is at the bottom and projecting toward you. Insert the tab on one side of the panel into the appropriate slot in the drive cage, bow the panel slightly, and fit the second tab into the slot in the other side of the cage. Make sure the sides of the panel fit flush against the sides of the drive cage.

Reorienting the External Drive Cage To accommodate a change in computer orientation (for example, from an upright to a rack configuration), you can reconfigure the external drive bays to remain horizontal as follows:

1. Remove the front-panel inserts from the front bezel.

2. Reposition the plastic frame surrounding the drive opening in the front bezel:

a. Facing the inside of the front bezel, press against the center of the frame with your thumbs until the frame bows sufficiently to loosen the tabs on the sides of the insert. Pull the frame out of the bezel.

b. Rotate the frame 90 degrees to match the new orientation of the drives.

c. Replace the frame in the front bezel and carefully press it into place.

3. Reinstall the front-panel inserts to match the new drive orientation.

4. Remove the computer cover and slide the system board tray out to the service position.

5. Remove the external drives from the drive bays (noting all cable connections); remove any metal inserts covering empty drive bays.

6. Reinstall the external drives to match the new system orientation, and reconnect cables as appropriate.

7. Close the system board tray.

8. Replace the front bezel and computer cover.

Hard-Disk Drives in External Bay

Figure 4-8. Hard-Disk Drives in External Bay

Two SCSI hard-disk drives can be installed in the external bay using the hard- disk drive carrier insert (see Figure 4-8). Drives mate to a small backplane board on the back of the insert; from there, they can be connected via a two- device ribbon cable either to a redundant arrays of independent disks (RAID) controller or to one of the Ultra2/LVD SCSI connectors on the system board.

CAUTION: Hot-pluggable drive installation and removal is not sup- ported for hard-disk drives installed in the external drive bay. Removing a drive while the system is turned on will result in a loss of data.

Remove a SCSI hard-disk drive from the external drive bay as follows:

1. Press inward on the two release tabs on the drive bay insert, and pull the insert about one inch out of the external bay.

2. Use a flat-blade screwdriver to remove the screw that secures the locking bar on the front of the insert, and remove the locking bar.

3. Open the drive-carrier handle to release the carrier, and slide the carrier toward you out of the insert.

When installing a drive in the insert, slide the drive in with the handle open until it stops, and then push the handle closed and slide the drive in the rest of the way. Replace the locking bar before installing the insert into the chassis.

If you are not replacing the drive, install a metal close-out panel on the front of the external bay and a front-panel insert on the front bezel.

Hard-Disk Drives

Figure 4-9. Hard-Disk Drive Removal

Remove a SCSI hard-disk drive from an internal drive bay as follows:

1. If the system does not have a PowerEdge Expandable RAID Con- troller installed, shut down the system and go to step 3.

CAUTION: Hot-pluggable drive installation and removal is not supported for systems without a Dell PowerEdge Expandable RAID Con- troller host adapter card. Removing a drive without turning the system off in this situation will result in a loss of data.

2. For systems with PowerEdge Expandable RAID Controllers, refer to your RAID controller documentation for information on prepar- ing the drive for removal. When the drive has been powered down, wait until the drive status indicators adjacent to the drive bay signal that the drive may be removed safely.

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

3. Unlock the hard-disk drive keylock (see Figure 4-9).

4. Squeeze the open side of the drive-carrier handle to release it, open the handle, and slide the carrier toward you until it is free of the drive bay.

Removing and Replacing Parts 4-15

CAUTION: Should you remove power from the SCSI backplane board (either by removing the power cable or during replacement of the system board battery), you may need to reflash your systems firmware.

The original firmware on the SCSI backplane is stored in EEPROM. However, if the SCSI backplane firmware is ever updated, the update is stored in volatile RAM. If power is removed from an updated back- plane board, the update will be lost and the board will revert to its original firmware in EEPROM.

If at system startup you receive the message Warning: Firmware is out-of-date, please update... , it is best to reflash all system firmware from your Dell Server Assistant CD.

System Board

Figure 4-27. System Board Removal

To remove the system board from the system board tray, perform the following steps. (If you are replacing the system board, you may want to remove the expansion cards, memory, processors, and processor guides and install them on the replacement system board.)

1. Remove the system board assembly (optional).

2. Note the slot numbers of any PCI cards you are migrating to the new system board so that you can install them in the same slots on the new board.

3. Remove the system board components you are migrating to the new system board.

4. Loosen the thumbscrew securing the system board to the tray (see Figure 4-27).

5. Slide the system board to the left as shown in Figure 4-27 (toward the inner expansion-card guide brackets) about a half inch to clear the chassis hooks, and remove the board.

If you are replacing the system board, install any components you removed from the old system board onto the replacement board. To retain the same system configuration and appropriate resource sharing, install PCI expansion cards in the same slots they were in on the old system board. Verify that the jumper settings on the new system board are correct.
