Connecting External Devices

When connecting external devices to your system, follow these guidelines:

• Most devices must be connected to a specific connector and device drivers must be installed before the device operates properly. (Device drivers are normally included with your operating system software or with the device itself.) See the documentation that accompanied the device for specific installation and configuration instructions.

• Always attach an external device while your system and the device are turned off. Next, turn on any external devices before turning on the system (unless the documentation for the device specifies otherwise).

See "Using the System Setup Program" on page 31 for information about enabling, disabling, and configuring I/O ports and connectors.

System and Setup 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 or Changing an Existing System Password" on page 41). 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. This procedure is described in "Disabling a Forgotten Password" on page 135.

Using the System Setup Program 39

Page 40

Using the System Password

After a system password is assigned, only those who know the password have full use of the system. When the System Password option is set to Enabled, the system prompts you for the system password after the system starts.

NOTE: If you have assigned a setup password (see "Using the Setup Password" on

page 42), the system accepts your setup password as an alternate system password.

Assigning a System Password

Before you assign a system password, enter the System Setup program and check the System Password option.

When a system password is assigned, the setting shown for the System

Passwo rd option is Enabled. If the setting shown for the Password Status is Unlocked, you can change the system password. If the Password Status

option is Locked, you cannot change the system password. When the system password feature is disabled by a jumper setting, the system password is Disabled, and you cannot change or enter a new system password.

When a system password is not assigned and the password jumper on the system board is in the enabled (default) position, the setting shown for the

System Password option is Not Enabled and the Password Status field is Unlocked. To assign a system password:

Unpack the drive and prepare it for installation. For instructions, see the documentation that accompanied the drive.

If you are installing a SCSI tape drive, you must have a SCSI

card installed (see "Installing an Expansion Card

" on page 72

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.

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

Memory

The four memory module connectors on the system board can accommodate from 512 MB to 8 GB of 667-MHz and 800-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: 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. See Figure 6-2 for slot locations.

Memory Module Upgrade Kits

The system is upgradable to 8 GB by installing combinations of 512-MB, 1-GB, and 2-GB 667-MHz or 800-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 can be 512 MB, 1 GB, or 2 GB.

• 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 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 8-GB Configurations (Microsoft® Windows® Operating System Only)

Your system supports a maximum of 8 GB of memory using four 2-GB memory modules. Current operating systems can use a maximum of 8 GB of address space; however, the amount of memory available to the operating system is slightly less than 8 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 7.4 GB of memory or less.

The following components require address space:

• System ROM

• Advanced Programmable Interrupt Controllers (APIC)

76 Installing System Components

Page 77

• 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 8 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.
