The power-on indicator lights when the system power is on.
The power button controls the DC power supply output to the system. When the system bezel is installed, the power
button is not accessible.
NOTE: When powering on the system, the video monitor can take from several seconds to over 2 minutes to display
an image, depending on the amount of memory installed in the system.
NOTE: On ACPI-compliant operating systems, turning off the system using the power button causes the system to
perform a graceful shutdown before power to the system is turned off.

The identification buttons on the front and back panels can be used to locate a particular system within a rack. When
one of these buttons is pushed, the LCD panel on the front and the blue system status indicator on the back blink
until one of the buttons is pushed again.
LCD panel
Provides system ID, status information, and system error messages.
The LCD lights during normal system operation. Both the systems management software and the identification
buttons located on the front and back of the system can cause the LCD to flash blue to identify a particular system.
The LCD lights amber when the system needs attention, and the LCD panel displays an error code followed by
descriptive text.
NOTE: If the system is connected to AC power and an error has been detected, the LCD lights amber regardless of
whether the system has been powered on.

Hard-Drive Indicator Codes
The hard-drive carriers have two indicators—the drive-activity indicator and the drive-status indicator. See Figure 1-2. In RAID configurations, the drive-status
indicator lights to indicate the status of the drive. In non-RAID configurations, only the drive-activity indicator lights; the drive-status indicator is off.

Table 1-3 lists the drive indicator patterns for RAID hard drives. Different patterns are displayed as drive events occur in the system. For example, if a hard
drive fails, 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: For non-RAID configurations, only the drive-activity indicator is active. The drive-status indicator is off.

Connecting External Devices
When connecting external devices to your system, follow these guidelines:
l
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.
l
Always attach external devices 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).
For information about individual connectors, see Jumpers and Connectors. For information about enabling, disabling, and configuring I/O ports and connectors,
Power Indicator Codes
The power button on the front panel controls the power to the system from the system's power supplies. The power indicator lights green when the system is
on.
The indicators on the redundant power supplies show whether power is present or whether a power fault has occurred (see Figure 1-4). Table 1-4 lists the
power supply indicator codes.

LCD Status Messages
The system's control panel LCD provides status messages to signify when the system is operating correctly or when the system needs attention.
The LCD lights blue to indicate a normal operating condition, and lights amber to indicate an error condition. The LCD scrolls a message that includes a status
code followed by descriptive text. Table 1-6 lists the LCD status messages that can occur and the probable cause for each message. The LCD messages refer
to events recorded in the System Event Log (SEL). For information on the SEL and configuring system management settings, see the systems management
software documentation.
CAUTION: Many repairs may only be done by a certified service technician. You should only perform troubleshooting and simple repairs as

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:
l
l
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:
l
l
l
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: Many repairs may only be done by a certified service technician. You should only perform troubleshooting and simple repairs as
authorized in your product documentation, or as directed by the online or telephone service and support team. Damage due to servicing that is not
authorized by Dell is not covered by your warranty. Read and follow the safety instructions that came with the product.

Running the System Diagnostics
Dell™ PowerEdge™ R805 Systems Hardware Owner's Manual
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 Server Administrator Diagnostics
To assess a system problem, first use the online Server Administrator diagnostics. If you are unable to identify the problem, then use the system diagnostics.
To access the online diagnostics, log into the Server Administrator home page, and then click the Diagnostics tab. For information about using diagnostics, see
the online help. For additional information, see the Server Administrator User's Guide.

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 two 2.5-
inch SAS or SATA hard drives. All drives connect to the system board through the SAS/SATA backplane board. See Figure 6-3. Hard drives are supplied in
special hot-pluggable drive carriers that fit in the hard-drive bays.
NOTICE: Before attempting to remove or install a drive while the system is running, see the documentation for the SAS controller daughter card to
ensure that the host adapter is configured correctly to support hot-plug drive removal and insertion.
NOTE: All installed drives must be either SAS or SATA. Mixed drive configurations are not supported.
NOTE: It is recommended that you use only drives that have been tested and approved for use with the SAS/SATA 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 hard drive, allow enough time for the formatting to be completed. Be aware that high-capacity hard drives can take a number of 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.
Remove the drive blank as you would the 2.5-inch hard drive carrier:
3. Slide the drive blank out until it is free of the drive bay.
Installing a Drive Blank
Install the hard drive blank as you would a 2.5-inch hard drive carrier:
2. Open the handle on the drive blank.
3. Insert the drive blank into the drive bay until the blank is fully seated.
4. Close the handle to lock the blank in place.
Removing a Hot-Plug Hard Drive
2. From 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 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.
4. Slide the hard drive out until it is free of the drive bay.
5. If you do not replace the hard drive, insert a drive blank in the vacated drive bay. See Installing a Drive Blank.
NOTICE: To maintain proper system cooling, all empty hard-drive bays must have drive blanks installed.
Installing a Hot-Plug Hard Drive
NOTICE: When installing a hard drive, ensure that the adjacent drives are fully installed. Inserting a hard-drive carrier and attempting to lock its handle
next to a partially installed carrier can damage the partially installed carrier's shield spring and make it unusable.

System Memory
You can upgrade your system memory to a maximum of 128 GB by installing 667-MHz registered parity DDR2 memory modules (DIMMs) in sets of 512-MB, 1-GB,
2-GB, 4-GB, or 8-GB single- or dual-ranked modules (quad-ranked modules are not supported). The memory sockets are located on the system board under
the memory module cooling shrouds and are split into two separate groups of eight sockets each. Each eight-socket group is adjacent to its respective
processor.
Your system hardware supports Non-Uniform Memory Architecture (NUMA). Each processor has its own memory controller and local memory for reduced access
times, but it can also access memory from another processor. This architecture improves system performance if an operating system is installed that supports
this feature.
NOTICE: To enable NUMA, run the System Setup program and disable the Node Interleaving option. See Using the System Setup Program.
General Memory Module Installation Guidelines
To ensure optimal performance of your system, observe the following guidelines when configuring your system memory.
l
l
Memory must be installed in configurations of four, eight, or sixteen DIMMs. The minimum configuration is four 512-MB DIMMs.
DIMMs must be installed in matched sets of identical speed, technology, and size in the following sockets:
¡
¡
¡
A1, A2, B1, and B2 — four identical DIMMs in this set
A3, A4, B3, and B4 — four identical DIMMs in this set
A5 through A8 and B5 through B8 — eight identical DIMMs in this set
l
l
Minimum configurations (four DIMMs) must occupy sockets A1, A2, B1, and B2.
A matched DIMM set can be mixed with another matched DIMM set of the next smaller size. For example, a DIMM set containing 2-GB DIMMs can be
mixed with another DIMM set containing 1-GB DIMMs, but not a set containing 512-MB DIMMs. The larger capacity DIMMs must occupy the lower-
numbered DIMM sockets.

Memory Sparing Support
Memory sparing is supported in systems that have one of the fully populated memory configurations shown in Table 3-1. The memory sparing feature must be
enabled in the Memory Information screen of the System Setup program. See Using the System Setup Program.
NOTE: The Memory sparing and node interleaving features cannot be used at the same time. To use memory sparing, you must disable the Node
Interleaving option in the System Setup program.
Memory sparing is applied independently to the two groups of DIMMs on opposite sides of the processor sockets. To support memory sparing, all DIMM
sockets within a DIMM group must be populated.
When enabled, memory sparing allocates and reserves ranks of memory from the installed DIMMs to act as spare memory in the event of a memory channel
failure. A memory channel uses paired DIMMs; for memory sparing to work, DIMMs must be paired as spares also.
Memory sparing allocates only the first rank of memory of a DIMM. For a single-rank DIMM, the entire capacity of the DIMM must be allocated for sparing along
with the adjacent single-rank DIMM to spare a memory channel. For dual-rank DIMMs, two DIMMs are also required for sparing, but as only the first rank of
each DIMM is allocated, only half of a dual-rank DIMM's capacity is allocated for sparing. The second ranks on both DIMMs are available memory.
Memory sparing calculates the appropriate DIMMs to spare by searching the DIMM sockets, starting with the higher-numbered socket pair (specifically, sockets
3 and 4 or sockets 7 and 8), for an amount of memory large enough to spare one of the available channels of memory. If the DIMMs in these sockets are
sufficient to spare a channel of the available memory, the first rank of each of those two DIMMs are spared. If the amount of memory is not large enough to
spare an available memory channel, the system spares the DIMM ranks in the lower-numbered sockets. Table 3-2 shows how memory sparing works in
various memory configurations.

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). 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.
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:
1. Verify that the Password Status option is set to Unlocked.
2. Highlight the System Password option and press <Enter>.
3. Type 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.
4. Press <Enter>.
5. To 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.
6. Either 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), 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:
1. Turn on or reboot your system by pressing <Ctrl><Alt><Del>.
2. Type your password and press <Enter>.
To disable the password security:
1. Turn on or reboot your system by pressing <Ctrl><Alt><Del>.
2. Type 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.
Deleting or Changing an Existing System Password
1. When prompted, press <Ctrl><Enter> to disable the existing system password.
If you are asked to enter your setup password, contact your network administrator.
2. Enter the System Setup program by pressing <F2> during POST.
3. Select the System Security screen field to verify that the Password Status option is set to Unlocked.
4. When prompted, type the system password.
5. Confirm 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
1. Enter the System Setup program and select the System Security option.
2. Highlight 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.
