Alert! Previous Processor Thermal Failure

The system encountered a problem while trying to configure a PCIe expansion card.

The OS Install Mode option in the System Setup program is set to On. This limits the amount of available memory to 256 MB because some operating systems will not complete installation with more than 2 GB of system memory.

The fan caused errors the last time the system was used.

The system failed to complete the boot routine three consecutive times for the same error.

The processor overheated the last time the system was used.

Ensure that the processor cooling shroud is properly installed. See "Troubleshooting System Cooling Problems" on page 86 and "Microprocessor" on page 62.

See "Troubleshooting Expansion Cards" on page 93.

Use only Dell supported processors. See the Getting Started Guide for a list of supported processors.

After the operating system is installed, enter the System Setup program and set the OS Install Mode option to Off. See "Using the System Setup Program" on page 27.

Ensure that nothing is blocking the airflow vents and that all fans are properly installed and operating correctly. See "Troubleshooting System Cooling Problems" on page 86.

Password Features

NOTICE: The password features provide a basic level of security for the data on your system. If your data requires

more security, use additional forms of protection, such as data encryption programs.

NOTICE: Anyone can access the data stored on your system if you leave the system running and unattended

without having a system password assigned or if you leave your system unlocked so that someone can disable the password by changing a jumper setting.

Your system is shipped to you without the system password feature enabled. If system security is a concern, operate your system only with system password protection.

To change or delete an existing password, you must know the password (see "Deleting an Existing System Password" on page 36). If you forget your password, you cannot operate your system or change settings in the System Setup program until a trained service technician changes the password jumper setting to disable the passwords, and erases the existing passwords.

) and configure the tape drive according to the documentation that

came with the tape drive, based on the following guidelines:

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). Set the drive’s SCSI ID to avoid conflicts with other devices on the SCSI bus. For the default SCSI ID setting, see the documentation provided with the drive.

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.

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.

Memory

The four memory module connectors on the system board can accommodate from 512 MB to 4 GB of 533-MHz and 667-MHz unbuffered ECC DDR II single or dual-rank memory modules. See Figure 6-2 for the location of the four memory module connectors.

NOTE: As shown in Figure 6-2, memory slots are not in numeric order on the system board. When installing

memory, take care to install it in the proper slots according to the configuration guidelines in Table 3-2. Installing memory in the wrong slots will significantly reduce system performance.

58 Installing System Components

Page 59

Memory Module Upgrade Kits

The system is upgradable to 4 GB by installing combinations of 512-MB and 1-GB 533-MHz or 667-MHz unbuffered ECC DDR II single or dual-rank memory modules. You can purchase memory upgrade kits from Dell.

Memory Module Installation Guidelines

• If only one memory module is installed, it must be installed in connector DIMM_1.

• If only one memory module is installed in connector DIMM_1, its capacity must be 512 MB.

• If more than one memory module is installed, the memory modules must be installed in pairs of matched memory size, speed, and technology.

• Memory modules must be installed in ordered pairs in connectors DIMM_1 and DIMM_2, and then DIMM_3 and DIMM_4.

• If a processor with a slower front-side bus rating than the memory is installed, the memory will operate at the processor’s slower front-side bus speed.

NOTICE: If you remove your original memory modules from the system during a memory upgrade, keep them

separate from any new memory modules that you may have, even if you purchased the new memory modules from Dell. Use only unregistered or unbuffered ECC DDR II memory modules.

Table 3-2 illustrates memory configuration guidelines. It is important to follow the slot installation configurations shown here to achieve maximum memory performance.

Addressing Memory With 4-GB Configurations (Microsoft® Windows® Operating System Only)

Your system supports a maximum of 4 GB of memory using four 1-GB memory modules. Current operating systems can use a maximum of 4 GB of address space; however, the amount of memory available to the operating system is slightly less than 4 GB.

NOTE: Depending on the type of PCI/PCIe expansion cards that are installed in your system, your system may only

support a maximum of 3.4 GB of memory or less.

Installing System Components 59

Page 60

The following components require address space:

• System ROM

• Advanced Programmable Interrupt Controllers (APIC)

• Integrated PCI devices (such as NICs) and SCSI controllers

• PCI expansion cards

At start-up, the BIOS identifies the components that require address space. The BIOS dynamically calculates the amount of reserved address space required. The BIOS then subtracts the reserved address space from 4 GB to determine the amount of usable space.

• If the total installed system memory is less than the usable space, all installed system memory is available for use only by the operating system.

• If the total installed system memory is equal to or greater than the usable address space, a small portion of installed memory is available for use by the operating system.

Running the System Diagnostics

If you experience a problem with your system, run the diagnostics before calling for technical assistance. The purpose of the diagnostics is to test your system's hardware without requiring additional equipment or risking data loss. If you are unable to fix the problem yourself, service and support personnel can use diagnostics test results to help you solve the problem.

Using Dell PowerEdge Diagnostics

To assess a system problem, first use the online Dell® PowerEdge® Diagnostics. Dell PowerEdge Diagnostics is a suite of diagnostic programs, or test modules, that include diagnostic tests on chassis and storage components such as hard drives, physical memory, communications and printer ports, NICs, CMOS, and more. If you are unable to identify the problem using the PowerEdge Diagnostics, then use the system diagnostics.

The files required to run PowerEdge Diagnostics for systems running supported Microsoft and Linux operating systems are available at system. For information about using diagnostics, see the

support.dell.com
