Solving Problems Described by LCD Status Messages

The code and text on the LCD can often specify a very precise fault condition that is easily corrected. For example, if the code E1418 CPU_1_Presence appears, you know that a microprocessor is not installed in socket 1.

In contrast, you might be able to determine the problem if multiple related errors occur. For example, if you receive a series of messages indicating multiple voltage faults, you might determine that the problem is a failing power supply.

Removing LCD Status Messages

For faults associated with sensors, such as temperature, voltage, fans, and so on, the LCD message is automatically removed when that sensor returns to a normal state. For example, if temperature for a component goes out of range, the LCD displays the fault; when the temperature returns to the acceptable range, the message is removed from the LCD. For other faults, you must take action to remove the message from the display:

???Clear the SEL ??? You can perform this task remotely, but you will lose the event history for the system.

???Power cycle ??? Turn off the system and disconnect it from the electrical outlet; wait approximately ten seconds, reconnect the power cable, and restart the system.

Any of these actions will remove fault messages, and return the status indicators and LCD colors to the normal state. Messages will reappear under the following conditions:

???The sensor returns to a normal state but fails again, resulting in a new SEL entry.

???The system is reset and new error events are detected.

???A failure is recorded from another source that maps to the same display entry.

System Messages

System messages appear on the screen to notify you of a possible problem with the system. Table 1-3 lists the system messages that can occur and the probable cause and corrective action for each message.

NOTE: If you receive a system message that is not listed in Table 1-3, check the documentation for the application that is running when the message appears or the operating system's documentation for an explanation of the message and recommended action.

CAUTION: Only trained service technicians are authorized to remove the system cover and access any of the components inside the system. See your Product Information Guide for complete information about safety precautions, working inside the computer, and protecting against electrostatic discharge.

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 47). 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 144.

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.

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 Password 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:

1Verify that the Password Status option is set to Unlocked.

2Highlight the System Password option and press <Enter>.

3Type your new system password.

You can use up to 32 characters in your password.

As you press each character key (or the spacebar for a blank space), a placeholder appears in the field.

The password assignment is not case-sensitive. However, certain key combinations are not valid. If you enter one of these combinations, the system beeps. To erase a character when entering your password, press <Backspace> or the left-arrow key.

NOTE: To escape from the field without assigning a system password, press <Enter> to move to another field, or press <Esc> at any time prior to completing step 5.

4Press <Enter>.

5To confirm your password, type it a second time and press <Enter>.

The setting shown for the System Password changes to Enabled. Exit the System Setup program and begin using your system.

6Either reboot your system now for your password protection to take effect or continue working.

NOTE: Password protection does not take effect until you reboot the system.

Using Your System Password to Secure Your System

NOTE: If you have assigned a setup password (see "Using the Setup Password" on page 47), the system accepts your setup password as an alternate system password.

When the Password Status option is set to Unlocked, you have the option to leave the password security enabled or to disable the password security.

To leave the password security enabled:

1Turn on or reboot your system by pressing <Ctrl><Alt><Del>.

2Type your password and press <Enter>.

To disable the password security:

1Turn on or reboot your system by pressing <Ctrl><Alt><Del>.

2Type your password and press <Ctrl><Enter>.

When the Password Status option is set to Locked whenever you turn on your system or reboot your system by pressing <Ctrl><Alt><Del>, type your password and press <Enter> at the prompt.

After you type the correct system password and press <Enter>, your system operates as usual.

If an incorrect system password is entered, the system displays a message and prompts you to re-enter your password. You have three attempts to enter the correct password. After the third unsuccessful attempt, the system displays an error message showing the number of unsuccessful attempts and that the system has halted and will shut down. This message can alert you to an unauthorized person attempting to use your system.

Even after you shut down and restart the system, the error message continues to be displayed until the correct password is entered.

NOTE: You can use the Password Status option in conjunction with the System Password and Setup Password options to further protect your system from unauthorized changes.

46 Using the System Setup Program

Deleting or Changing an Existing System Password

1When prompted, press <Ctrl><Enter> to disable the existing system password. If you are asked to enter your setup password, contact your network administrator.

2Enter the System Setup program by pressing <F2> during POST.

3Select the System Security screen field to verify that the Password Status option is set to Unlocked.

4When prompted, type the system password.

5Confirm that Not Enabled is displayed for the System Password option.

If Not Enabled is displayed for the System Password option, the system password has been deleted. If Enabled is displayed for the System Password option, press the <Alt><b> key combination to restart the system, and then repeat steps 2 through 5.

Using the Setup Password

Assigning a Setup Password

You can assign (or change) a setup password only when the Setup Password option is set to Not Enabled. To assign a setup password, highlight the Setup Password option and press the <+> or <???> key. The system prompts you to enter and verify the password. If a character is illegal for password use, the system beeps.

NOTE: The setup password can be the same as the system password. If the two passwords are different, the setup password can be used as an alternate system password. However, the system password cannot be used in place of the setup password.

You can use up to 32 characters in your password.

As you press each character key (or the spacebar for a blank space), a placeholder appears in the field.

The password assignment is not case-sensitive. However, certain key combinations are not valid. If you enter one of these combinations, the system beeps. To erase a character when entering your password, press <Backspace> or the left-arrow key.

After you verify the password, the Setup Password setting changes to Enabled. The next time you enter the System Setup program, the system prompts you for the setup password.

A change to the Setup Password option becomes effective immediately (restarting the system is not required).

Operating With a Setup Password Enabled

If Setup Password is set to Enabled, you must enter the correct setup password before you can modify most of the System Setup options. When you start the System Setup program, the program prompts you to enter a password.

If you do not enter the correct password in three attempts, the system lets you view, but not modify, the System Setup screens???with the following exception: If System Password is not set to Enabled and is not locked through the Password Status option, you can assign a system password (however, you cannot disable or change an existing system password).

NOTE: You can use the Password Status option in conjunction with the Setup Password option to protect the system password from unauthorized changes.

Deleting or Changing an Existing Setup Password

1Enter the System Setup program and select the System Security option.

2Highlight the Setup Password option, press <Enter> to access the setup password window, and press <Enter> twice to clear the existing setup password.

The setting changes to Not Enabled.

Hard Drives

This subsection describes how to install and configure SAS or SATA hard drives in the system's internal hard-drive bays. Your system features up to six 3.5-inch hard drives, or eight 2.5-inch hard drives. All drives connect to the system board through one of three optional SAS backplane boards. See "SAS Backplane Board Connectors" on page 139 for information on these backplane options.

NOTE: Depending on the hard drive configuration you ordered, your hard drive(s) may come with a drive interposer that allows your SATA drive to attach to the SAS connector on the backplane.

Before You Begin

Hard drives are supplied in special hot-pluggable drive carriers that fit in the hard-drive bays. Depending on your configuration, you received one of the following two drive carrier types:

???SATA drive carrier ??? Usable only with a SATA hard drive.

???SATAu drive carrier ??? Usable with either a SAS hard drive or a SATA hard drive with a universal interposer card. The interposer card provides enhanced functionality that makes the SATA hard drive usable in some storage systems.

NOTICE: Before attempting to remove or install a drive while the system is running, see the documentation for the optional SAS RAID controller daughter card to ensure that the host adapter is configured correctly to support hot- plug drive removal and insertion.

NOTE: It is recommended that you use only drives that have been tested and approved for use with the SAS backplane board.

You may need to use different programs than those provided with the operating system to partition and format SAS or SATA hard drives.

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

When you format a high-capacity 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.

Removing a Drive Blank

NOTICE: To maintain proper system cooling, all empty hard-drive bays must have drive blanks installed. If you remove a hard-drive carrier from the system and do not reinstall it, you must replace the carrier with a drive blank.

The process for removing a drive blank depends on whether your system is configured with 3.5-inch or 2.5-inch hard drives.

For 3.5-inch hard drive configurations:

1Remove the front bezel, if attached. See "Removing the Front Bezel" on page 53.

2Insert your finger under the shrouded end of the blank and press in on the latch to eject the blank outward from the bay.

3Pry the ends of the blank outward until the blank is free.

For 2.5-inch hard drive configurations, remove the blank as you would the 2.5-inch hard drive carrier:

1Remove the front bezel, if attached. See "Removing the Front Bezel" on page 53.

2Open the drive blank release handle to release the blank. See Figure 3-4.

3Slide the drive blank out until it is free of the drive bay.

56 Installing System Components

Installing a Drive Blank

The process for installing a drive blank depends on whether your system is configured with 3.5-inch or 2.5-inch hard drives.

For 3.5-inch hard drive configurations, the drive blank is keyed to ensure correct insertion into the drive bay. To install a 3.5-inch drive blank, insert and rotate in the keyed side of the blank into the drive bay and press evenly on the other end of the blank until it is fully inserted and latched.

For 2.5-inch hard drive configurations, install the hard drive blank as a 2.5-inch hard drive carrier:

1Remove the front bezel, if attached. See "Removing the Front Bezel" on page 53.

2Open the handle on the drive blank.

3Insert the drive blank into the drive bay until the blank is fully seated.

4Close the handle to lock the blank in place.

5Replace the front bezel, if it was removed in step 1.

Removing a Hot-Plug Hard Drive

1Remove the front bezel, if attached. See "Removing the Front Bezel" on page 53.

2From the RAID management software, prepare the drive for removal and wait until the hard-drive indicators on the drive carrier signal that the drive can be removed safely. See your SAS RAID controller documentation for information about hot-plug drive removal.

If the drive has been online, the green activity/fault indicator will flash as the drive is powered down. When both drive indicators are off, the drive is ready for removal.

3Open the drive carrier release handle to release the drive. See Figure 3-4.

4Slide the hard drive out until it is free of the drive bay.

5If you do not replace the hard drive, insert a drive blank in the vacated drive bay. See "Installing a Drive Blank" on page 57.

NOTICE: To maintain proper system cooling, all empty hard-drive bays must have drive blanks installed.

You can upgrade your system memory to a maximum of 32 GB by installing 533MHz or 667MHz fully buffered (FB) DDR II memory modules in sets of 256-MB, 512-MB, 1-GB, 2-GB, or 4-GB. The eight memory sockets are located on the system board under the cooling shroud adjacent to the power supply bays. See Figure 6-2. You can purchase memory upgrade kits from Dell.

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 533 MHz or 667 MHz DDR II FB-DIMMs.

The memory module sockets are divided into two equal branches (0 and 1). Each branch consists of two channels:

???Channel 0 and channel 1 are in branch 0.

???Channel 2 and channel 3 are in branch 1.

Each channel consists of two DIMM sockets:

???Channel 0 contains DIMM_1, DIMM_5.

???Channel 1 contains DIMM _2, DIMM_6.

???Channel 2 contains DIMM_3, DIMM_7.

???Channel 3 contains DIMM _4, DIMM _8.

The first DIMM socket of each channel has white release tabs.

General Memory Module Installation Guidelines

To ensure optimal performance of your system, observe the following guidelines when configuring your system memory.

???Use only qualified Fully-Buffered DIMMs (FBDs). FBDs can be either single-ranked or dual-ranked. FBDs marked with a 1R are single-ranked and modules marked with a 2R are dual-ranked.

???A minimum of two identical FBDs must installed.

???DIMM sockets must be populated by lowest number first.

???FBDs must be installed in pairs of matched memory size, speed, and technology, and the total number of FBDs in the configuration must total two, four, or eight. For best system performance, all four, or eight FBDs should be identical memory size, speed, and technology.

???Memory sparing and memory mirroring require eight FBDs, and all FBDs must be of identical memory size, speed, and technology.

???Memory sparing and memory mirroring cannot be implemented at the same time.

Non-Optimal Memory Configurations

System performance can be affected if your memory configuration does not conform to the preceding installation guidelines. Your system may issue an error message during startup stating that your memory configuration is non-optimal.

Memory Sparing Support

The system supports memory sparing if eight identical memory modules are installed in the system. The memory sparing feature must be enabled in the System Setup program and can be used only if memory mirroring is not enabled.

Memory sparing allocates four ranks of DIMM memory to the spare bank. These four ranks consist of the first rank of memory in DIMM sockets 1 through 4. For single-rank DIMMs, the entire capacity of the four DIMMs is allocated to sparing whereas for dual-rank DIMMs, only half of the four-DIMM capacity is allocated to sparing. Table 3-2 shows how memory sparing splits the available and spared memory in each of the single- and dual-ranked memory module combinations.

Table 3-2. Memory Sparing Configurations

Memory Mirroring Support

The system supports memory mirroring if eight identical memory modules are installed in the system. Mirroring must be enabled in the System Setup program and can be used only if memory sparing is not enabled. In a mirrored configuration, the total available system memory is one-half of the total installed memory.
