Keyboard and Mouse Connectors
Video Connectors
USB Connectors
Integrated NIC Connectors
The I/O ports and connectors on your system are the gateways through which the system communicates with external devices such as a keyboard, mouse,
and monitor. Figure B-1 identifies back-panel I/O ports and connectors. Figure B-2 identifies front-panel I/O ports and connectors.
Figure B-1. Back-Panel I/O Ports and Connectors
Figure B-2. Front-Panel I/O Ports and Connectors
Serial Ports
The integrated serial ports use 9-pin D-subminiature connectors on the back panel. These ports support devices such as external modems, printers, plotters,
and mice that require serial data transmission (the transmission of data one bit at a time over one line).
Most software uses the term COM (for communications) plus a number to designate a serial port (for example, COM1 or COM2). The default designations of
your system's integrated serial ports are COM1 and COM2.
Serial Port Connector
If you reconfigure your hardware, you may need pin number and signal information for the serial port connector. Figure B-3 illustrates the pin numbers for the
serial port connector and Table B-1 defines the pin assignments and interface signals for the serial port connector.

Adding an Expansion Card Containing Serial or Parallel Ports
The system has an autoconfiguration capability for the serial ports. This feature lets you add an expansion card containing a serial port that has the same
designation as one of the integrated ports, without having to reconfigure the card. When the system detects the duplicate serial port on the expansion card, it
remaps (reassigns) the integrated port to the next available port designation.
Both the new and the remapped COM ports share the same IRQ setting, as follows:
COM1, COM3: IRQ4 (shared setting)
COM2, COM4: IRQ3 (shared setting)
These COM ports have the following I/O address settings:
COM1:
COM2:
COM3:
COM4:
3F8h
2F8h
3E8h
2E8h
For example, if you add an internal modem card with a port configured as COM1, the system then sees logical COM1 as the address on the modem card. It
automatically remaps the integrated serial port that was designated as COM1 to COM3, which shares the COM1 IRQ setting. (Note that when you have two
COM ports sharing an IRQ setting, you can use either port as necessary but you may not be able to use them both at the same time.) If you install one or
more expansion cards with serial ports designated as COM1 and COM3, the corresponding integrated serial port is disabled.
Before adding a card that remaps the COM ports, check the documentation that accompanied your software to make sure that the software can be mapped to
the new COM port designation.
To avoid autoconfiguration, you may be able to reset jumpers on the expansion card so that the card's port designation changes to the next available COM
number, leaving the designation for the integrated port as is. Alternatively, you can disable the integrated ports through the System Setup program. The
documentation for your expansion card should provide the card's default I/O address and allowable IRQ settings. It should also provide instructions for
readdressing the port and changing the IRQ setting, if necessary.
For general information on how your operating system handles serial and parallel ports, and for more detailed command procedures, see your operating
system documentation.
Keyboard and Mouse Connectors
The system uses a PS/2-style keyboard and supports a PS/2-compatible mouse. Cables from both devices attach to 6-pin, miniature DIN connectors on the
front and back panels of your system.
NOTE: To enable the front-panel PS-2 connector, a monitor must be connected to the front-panel video connector. When a monitor is connected to the
front panel, the back-panel keyboard, mouse, and video are all disabled.
NOTE: To connect a keyboard and mouse to the front of the system, either use a PS/2 Y adapter to connect both a keyboard and mouse to the PS/2
connector, or use a PS/2 keyboard and a USB mouse.
Mouse driver software can give the mouse priority with the microprocessor by issuing IRQ12 whenever a new mouse movement is detected. The driver
software also passes along the mouse data to the application program that is in control.
Keyboard Connector
If you reconfigure your hardware, you may need pin number and signal information for the keyboard connector. Figure B-4 illustrates the pin numbers for the
keyboard connector. Table B-2 and Table B-3 defines the pin assignments and interface signals for the keyboard connector.

Video Connectors
The system uses a 15-pin high-density D-subminiature connector on the front and back panels for attaching a VGA-compatible monitor to your system. The
video circuitry on the system board synchronizes the signals that drive the red, green, and blue electron guns in the monitor.
Guidelines
NOTE: When a monitor is connected to the front panel, the back-panel keyboard, mouse, and video are all disabled.
l
This system provides two video connectors, one on the back panel, and one on the front panel. If the monitor is connected to the front-panel video
connector, the back-panel video connector is disabled.
l
The keyboard and mouse must be connected to the same panel as the monitor. For example, if the monitor is connected to the front-panel video
connector, the keyboard and mouse must also be connected to the keyboard/mouse front-panel connector. This connector is a PS/2 connector and the
keyboard connection is the default. To use both the keyboard and mouse from the front-panel connector, you must use a Y-cable.
If you reconfigure your hardware, you may need pin number and signal information for the video connector. Figure B-6 illustrates the pin numbers for the video
connector, and Table B-5 defines the pin assignments and interface signals for the video connector.

USB Connectors
Your system contains a single USB connector on the front control panel, and two USB connectors on the rear panel for attaching USB-compliant devices. USB
devices are typically peripherals such as mice, keyboards, and system speakers.
NOTICE: Do not attach a USB device or a combination of USB devices that draw a maximum current over 500 mA per channel on +5 V. Attaching devices
that exceed this threshold may cause the USB ports to shut down. See the documentation that accompanied the USB devices for their maximum current
ratings.
If you reconfigure your hardware, you may need pin number and signal information for the USB connectors. Figure B-7 illustrates the USB connector and

Integrated NIC Connectors
Your system has two integrated 10/100/1000–Mbps NICs. The 10/100/1000-Mbps NICs provide faster communication between servers and workstations and
efficient utilization of host resources, freeing more of the system resources for other applications. Both NICs support 10 Base-T, 100 Base-TX, and 1000 Base-T
Ethernet standards.
Both NICs include a Wake On LAN feature that enables the system to be started by a special LAN signal from a systems management console. Wake On LAN
provides remote system setup, software downloading and installation, file updates, and asset tracking after hours and on weekends when LAN traffic is
typically at a minimum.
Network Cable Requirements
Your system's RJ45 NIC connectors are designed for attaching a UTP Ethernet cable equipped with standard RJ45-compatible plugs. Press one end of the UTP
cable into the NIC connector until the plug snaps securely into place. Connect the other end of the cable to an RJ45 jack wall plate or to an RJ45 port on a UTP
concentrator or hub, depending on your network configuration. Observe the following cabling restrictions for 10 Base-T, 100 Base-TX, and 1000 Base-T
networks.
NOTICE: To avoid line interference, voice, and data lines must be in separate sheaths.
l
Use Category 5 or greater wiring and connectors.
l
The maximum cable run length (from a system to a hub) is 328 ft (100 m).
l
You can find guidelines for operation of a network can be found in "Systems Considerations of Multi-Segment Networks" in the IEEE 802.3 standard.

Installing and Configuring SCSI Drivers
Dell™ PowerEdge™ 2650 Systems User's Guide The SCSISelect Utility
This section describes how to install and configure the SCSI device drivers included with your system. These device drivers are designed to work with the AIC
7899W U160 SCSI controller on the system board. Both channels are connected to the backplane. Neither channel is available for external connection.
If you are using an optional RAID controller, see your RAID controller documentation for information on installing your SCSI device drivers.
For instructions on installing hardware devices such as diskette drives, CD drives, and tape drives, see "Installing Drives" in the Installation and Troubleshooting
Guide. After the SCSI devices are installed, install and configure any SCSI device drivers to enable them to communicate with your operating system.
SCSI device drivers are provided for the following operating systems:
l
Microsoft® Windows® 2000 Server and Advanced Server
l
Windows NT® 4.0 Server, Server Enterprise Edition
l
Red Hat Linux 7.x
See "Using the Dell OpenManage Server Assistant CD" for instructions on creating a diskette of drivers for your operating system. For instructions on
configuring the SCSI device drivers, see the documentation that came with your operating system. You may also need to use the SCSISelect utility, discussed
in this section.
The SCSISelect Utility
The BIOS for your system's integrated SCSI controller includes the menu-driven SCSISelect configuration utility, which allows you to change SCSI controller
settings without opening the system. SCSISelect also contains SCSI disk utilities that let you perform a low-level format or verify the disk media of your SCSI
hard drives.
NOTE: The SCSISelect utility cannot be used to install and configure SCSI drivers for the optional ROMB card. For more information on installing and
configuring SCSI drivers with the optional ROMB card, see your RAID controller documentation.
Starting the SCSISelect Utility
You can start the SCSISelect utility by pressing <Ctrl><a> when the following prompt appears briefly during start-up:
Press <CTRL><A> for SCSISelect™ Utility! The first menu allows you to select channel A or channel B. The second menu contains Configure/View Host Adapter Settings and SCSI Disk Utilities
options.
Using SCSISelect Menus
SCSISelect uses menus to list options that you can select. To select an option, press the up- and down-arrow keys to move the cursor to the option; then
press <Enter>.
In some cases, selecting an option displays another menu. You can return to the previous menu at any time by pressing <Esc>. To restore the original
SCSISelect default values, press <F6>.
SCSISelect Default Settings
Default settings for the integrated SCSI controller are shown in Table C-1. These default settings are appropriate for most PCI systems. Run SCSISelect only if
you need to change any of the default settings.
NOTE: To change the configuration settings, you must run the SCSISelect utility.
For situations in which you might want or need to change the settings, see the description of each setting in the following subsections. To change any of the
default settings or to format or verify a disk, see "Using the SCSI Disk Utilities."

SCSI Bus Interface Definitions
The basic host adapter settings are the SCSISelect settings most likely to require modification:
l
Host Adapter SCSI ID — Sets the host adapter's SCSI ID. The default setting is SCSI ID 7, which allows the host adapter to support narrow SCSI
devices in addition to wide SCSI devices. Dell recommends that you leave the host adapter set to SCSI ID 7.
l
SCSI Parity Checking — Determines whether the host adapter verifies the accuracy of data transfer on the SCSI bus. The default setting is Enabled.
You should disable SCSI Parity Checking if any SCSI device connected to the host adapter does not support SCSI parity; otherwise, leave it enabled.
Most SCSI devices support SCSI parity. If you are unsure whether a device supports SCSI parity, consult the documentation for the device.
l
Host Adapter SCSI Termination — Sets termination on the host adapter. The default setting for the AIC-7899 host adapter is Enabled or Automatic.
Dell recommends that you leave this option set to the default.
Boot Device Options
The boot device options allow you to specify the device from which to boot your system:
l
Boot Channel — Specifies the boot channel (A or B) for the dual-channel Adaptec 7899 host adapter. The default is A First.
l
Boot SCSI ID — Specifies the SCSI ID of the boot device on the selected Boot Channel.
l
Boot LUN Number — Allows you to specify a particular logical unit number (LUN) from which to boot your boot device if your boot device has multiple
LUNs and BIOS Multiple LUN Support is enabled (see "SCSI Device Configuration Settings"). The default setting is LUN 0.
SCSI Device Configuration Settings
The SCSI device Configuration settings allow you to configure certain parameters for each device on the SCSI bus. To configure a specific device, you must
know the SCSI ID assigned to that device. If you are not sure of the SCSI ID, see "Using the SCSI Disk Utilities."
l
Sync Transfer Rate MB/sec — Sets the maximum synchronous data transfer rate that the host adapter supports.
The AIC-7899 host adapter supports rates up to 160 MB/sec. The default for the AIC-7899 host adapter is 160 MB/sec.
If the host adapter is set to not negotiate for synchronous data transfer, the maximum synchronous transfer rate is the maximum rate that the host
adapter accepts from the device during negotiation. (This setting is standard SCSI protocol.)
l
Initiate Wide Negotiation — Determines whether the host adapter attempts 16-bit data transfer instead of 8-bit data transfer. The default is Yes.
NOTE: Some 8-bit SCSI devices may have trouble handling wide negotiation, which may result in erratic behavior or a hang condition. For these
devices, set Initiate Wide Negotiation to No.
When this option is set to Yes, the host adapter attempts 16-bit data transfer. When this option is set to No, 8-bit data transfer is used unless the SCSI
device itself requests wide negotiation. The effective transfer rate is doubled when 16-bit data transfer is used because the data path for wide SCSI is
twice the size of normal 8-bit SCSI.
l
Enable Disconnection (sometimes called disconnect/reconnect) — Determines whether the host adapter allows the SCSI device to disconnect from the
SCSI bus. Enabling disconnection allows the host adapter to perform other operations on the SCSI bus while the SCSI device is temporarily
disconnected. The default setting is Yes.
Leave Enable Disconnection set to Yes if two or more SCSI devices are connected to the host adapter. This optimizes SCSI bus performance. If only
one SCSI device is connected to the host adapter, set Enable Disconnection to No to achieve slightly better performance.
l
Send Start Unit Command — Determines whether the start unit command is sent to the SCSI device during the boot routine. The default is Yes.
Setting this option to Yes reduces the load on your system's power supply by allowing the host adapter to start SCSI devices one at a time when you
boot your system. When this option is set to No, the devices are allowed to start at the same time. Most devices require you to set a jumper before they
can respond to this command.
NOTE: For many devices, if Send Start Unit Command is set to Yes, the boot routine time will vary depending on how long it takes each drive to
start.
l
Enable Write Back Cache — Signals the completion of a write request as soon as the data is in cache. Actual writing to the disk occurs at a later time.
The default setting is N/C or Yes.
l
BIOS Multiple LUN Support — Provides support for peripherals that contain multiple SCSI devices, such as autoloading tape drives and CD-ROM
changers.
NOTE: The setting for BIOS Multiple LUN Support must be No or Enabled (default) if a tape autoloader is connected.
l
Include in BIOS Scan — Enables you to set whether the system BIOS scans this device during system start-up. The default is Yes.
Advanced Configuration Settings
The advanced host adapter settings should not be changed unless absolutely necessary. Values are set by Dell, and changing them may cause conflicts with
the SCSI devices.
l
Reset SCSI Bus at IC Initialization — Enables the SCSI bus to be reset when the controller is initialized. The default is Enabled.
l
Display <Ctrl><a> Message During BIOS Initialization — Determines whether the Press <CTRL><A> for SCSISelect (TM) Utility! message appears
on your screen during system start-up. The default setting is Enabled. If this setting is disabled, you can still run the SCSISelect utility by pressing
<Ctrl><a> after the host adapter BIOS banner appears.
l
Extended BIOS Translation For DOS Drives > 1 GB — Determines whether extended translation is available for SCSI hard drives with capacities
greater than 1 GB. The default setting is Enabled.
NOTICE: Back up your hard drive before you change the translation scheme. All data is erased when you change from one translation scheme to
another.
The standard translation scheme for SCSI host adapters provides a maximum accessible capacity of 1 GB. To support hard drives larger than 1 GB, the
78xx series host adapters include an extended translation scheme that supports hard drives as large as 8 GB, with a maximum partition size of 2 GB
under the DOS operating system.
It is not necessary to enable the Extended BIOS Translation setting if you are using another operating system, such as Novell NetWare.
When you partition a hard drive larger than 1 GB, use the MS-DOS® fdisk utility as you normally would. Because the cylinder size increases to 8 MB
under extended translation, the partition size you choose must be a multiple of 8 MB. If you request a size that is not a multiple of 8 MB, fdisk rounds up
to the nearest whole multiple of 8 MB.
l
Silent/Verbose Mode — Displays the host adapter information during system start-up. The default is Verbose.
l
Host Adapter BIOS — Enables or disables the host adapter BIOS. The default setting is Enabled.
NOTE: Several SCSISelect options are not valid unless the host adapter BIOS is enabled.
If you are booting from a SCSI hard drive connected to the host adapter, the BIOS must be enabled. You should disable the host adapter BIOS if the
peripherals on the SCSI bus (for example, CD drives) are all controlled by device drivers and do not need the BIOS.
l
Domain Validation — Instructs the host adapter not to accept a negotiated speed until a validation test is successfully performed. After determining the
speed that a target device is capable of, the host adapter sends a Write Buffer command to the target device. The data transfer occurs at the full
speed initially. The initiator reads and tests the data and identifies any parity or cyclic redundancy check (CRC) errors. If the test fails, the initiator lowers its speed and repeats the test. In this manner, a compatible speed will be found and locked in before user data transfers begin. The default is
Enabled.
l
Support Removable Disks Under BIOS As Fixed Disks — Controls which removable-media drives are supported by the host adapter BIOS. The default
setting is Boot Only. The following choices are available.
NOTICE: If a removable-media SCSI device is controlled by the host adapter BIOS, do not remove the media while the drive is on or you may lose data.
If you want to be able to remove media while the drive is on, install your removable-media device driver and set this option to Disabled.
¡
Boot Only — Only the removable-media drive designated as the boot device is treated as a hard drive.
¡
All Disks — All removable-media drives supported by the BIOS are treated as hard drives.
¡
Disabled — No removable-media drives are treated as hard drives. In this situation, software drivers are needed because the drives are not
controlled by the BIOS.
l
BIOS Support For Bootable CD-ROM — Determines whether the host adapter BIOS provides support for booting from a CD drive. The default setting is
Enabled.
l
BIOS Support For Int 13 Extensions — Determines whether the host adapter BIOS supports disks with more than 1024 cylinders. The default setting is
Enabled.
Using the SCSI Disk Utilities
To access the SCSI disk utilities, select SCSI Disk Utilities from the menu that appears when you start SCSISelect. When the option is selected, SCSISelect
immediately scans the SCSI bus (to determine the devices installed) and displays a list of all SCSI IDs and the device assigned to each ID.
When you select a specific ID and device, a menu appears, displaying the Format Disk and Verify Disk Media options.
NOTICE: The Format Disk option destroys all data on the hard drive.
l
Format Disk — Runs a utility that allows you to perform a low-level format on a hard drive. Most SCSI disk drives are formatted at the factory and do
not need to be formatted again. The Adaptec Format Disk utility is compatible with the majority of SCSI disk drives.
l
Verify Disk Media — Runs a utility that allows you to scan the media of a hard drive for defects. If the utility finds bad blocks on the media, it prompts
you to reassign them; if you select Yes, those blocks are no longer used. You can press <Esc> at any time to exit the utility.
Exiting SCSISelect
To exit SCSISelect, press <Esc> until a message prompts you to exit. (If you changed any 78xx series host adapter settings, you are prompted to save the
changes before you exit.) At the prompt, select Yes to exit, and then press any key to reboot the system. Any changes that you made in SCSISelect take effect
after the system boots. (You can select No at the prompt if you are not ready to exit SCSISelect.)

Console redirection allows you to maintain a system from a remote location by re-directing keyboard input and text output through the serial port. Graphic
output is not redirected. Console redirection can be used under MS-DOS® for tasks such as setting up a common BIOS configuration or setting up a RAID
configuration. In a typical installation, the system is connected to a port concen-trator that allows you to connect several systems using a shared modem. After
you use a modem or other remote connection to log into the port concentrator, you can select which system you want to manage with console redirection. This
section describes the simplest connection possible: connecting to a system with a null modem cable.
Minimum Hardware and Connection Requirements
To use console redirection, you must have the following:
l
An available serial port (COM port) on a client system
This port must not conflict with any other ports on the system.
l
Available serial port (COM) on the server
For systems with two available serial ports, you can use either the COM 1 or COM 2 port.
l
A null modem cable to connect the server to the client system
Software Requirements
Your remote terminal emulation software should meet the following specifications:
l
ANSI or VT100/220 terminal emulation with a window size of 80 x 25 characters
l
9600, 19.2 K, 57.6 K, or 115.2 Kbps using serial (COM) ports
l
Recommended: the ability to create keyboard command macros
All versions of the Microsoft® Windows® operating systems come with Hyper-Terminal terminal emulation software. However, the version of HyperTerminal
included with most Windows operating systems does not provide the correct screen size, the arrow and function keys do not work, and there is no method of
creating macros. Dell recommends that you either upgrade your version of HyperTerminal to HyperTerminal Private Edition 6.1 or later or select new terminal
emulation software.
Configuring Console Redirection on the System
Console redirection is configured through the System Setup program (see "Using the System Setup Program" for instructions). The Console Redirection option
displays a screen that allows you to configure console redirection. The submenu allows you to turn the feature on or off, select the remote terminal type, and
enable or disable redirection after booting. The options available are listed in Table D-1.

If you select VT100/220 but not all the characters are visible on the screen, go back to the System Setup program and select ANSI as your terminal type.
ANSI can display the full set of ASCII characters.
Configuring Console Redirection on the Client System
NOTE: The examples in this document assume that you have upgraded to Hilgraeve's HyperTerminal Private Edition 6.1 or later. If you are using other
terminal emulation software, see the help file for that software.
Configuring the Ports
1.
Click the Start button, point to Programs—> Accessories—> Communications, and click HyperTerminal.
2.
Enter any name for the new connection and select any icon.
3.
Click OK.
4.
From the Connect to pull-down menu, select a COM port available on your client system and click OK.
If no COM port is available and you do not have a Dell system, you will need to contact technical support for your client system.
After you have selected an available COM port, the COM port properties window is displayed.
5.
Select Bits per second.
Console redirection supports 9600, 19.2 K, 57.6 K, or 115.2 K bps.
6.
Set Data bits to 8.
7.
Set Parity to None.
8.
Set Stop bits to 1.
9.
Set Flow control to Hardware.
10.
Click OK.
Configuring the Terminal Settings
After you configure the ports, configure the terminal settings by performing the following steps:
1.
In HyperTerminal, click File, click Properties, and select the Settings tab.
2.
Ensure that the Function, arrow, and ctrl keys act as field is set to Terminal Keys.
3.
Ensure that the Backspace key sends field is set to Ctrl+H.
4.
Change the Emulation setting from Auto detect to ANSI or VT100/220.
This setting should be the same as the setting you selected for the Console Redirection option on the server.
When you click Terminal Setup, you should see a setting for the number of rows and columns.
5.
Change the number of rows from 24 to 25 and leave the number of columns at 80. If you do not have these settings, this is an indication that you must
upgrade your terminal emulation software.
Rebooting the System
Console redirection is designed to yield control of the serial ports to the operating system. This configuration allows serial debugging and redirection of the
operating system to function correctly without interference from the system BIOS.
To use console redirection to shut down a system and troubleshoot it or to change SCSI BIOS configurations, perform the following steps:
1.
Reboot the system. See Table D-4, for a recommendation on how to do this.
2.
When the system begins to reboot, use console redirection to watch and interact with the system during the POST. While the system is booting, you
can do the following:
l
Enter the System Setup program.
l
Enter the SCSI setup menus.
l
Run utilities on the utility partition.
l
Update firmware and BIOS (flash the system).
NOTE: To use console redirection to run utilities on the utility partition, the utility partition must have been created using Dell OpenManage™ Server Assistant version 6.3.1 or later.
Configuring Special Keys
Console redirection uses ANSI or VT100/220 terminal emulation, which are limited to basic ASCII characters. There are no function keys, arrow keys, or control
keys in this character set. However, most BIOS software requires the use of function keys and control keys for ordinary functions. You can emulate a function
key or control key by using a special key sequence, called an escape sequence, to represent a specific key.
For console redirection, an escape sequence starts with an escape character. This character can be entered in a number of different ways, depending on the
requirements of your terminal emulation software. For example, 0x1b, ^[, and <Esc> all refer to the same escape character. Some terminal software uses
predefined macros to send the proper escape sequences. In HyperTerminal, you can define macros by selecting Key Macros from the View menu. Macros can
be assigned to almost any possible key for almost any key combination. Create a macro for each of your function keys. Table D-2 and Table D-3 list the
VT100/220 escape sequences that must be sent to represent a special key or command.
NOTE: When defining macros in HyperTerminal, you must press <Ins> before <Esc> to signify that you are sending an escape sequence rather than
escaping out of the dialog box. If you do not have these settings, this is an indication that you must upgrade your terminal emulation software.

Your system is a multipurpose, highly-available, rack-dense server with two Intel® Xeon™ microprocessors.
This section describes the major hardware and software features of your system and provides information about the system status indicators, and indicators
on the system's front and back panels. It also provides information about other documents you may need when setting up your system and how to obtain
technical assistance.
System Status Indicators
The system's bezel has an indictor that can represent system status when the bezel is installed (see Figure 1-1). The indicator signifies when the system is
operating properly, when the system needs attention, or when the system is being identified (see "System Identification Indicators"). The back-panel indicator
connector allows an indicator to be attached that will function the same as the bezel system status indicator. A caution code signifies a problem with
microprocessors, power supply, system or power-supply fans, system temperature, hard drives, system memory, expansion cards, or the integrated SCSI
controller. (See your Installation and Troubleshooting Guide for more information.) When the bezel is off, the LCD status display assumes all of the functions of
the system status indicator (see "Status LCD").
Table 1-1 and Table 1-2 list the system's status indicator codes.

Power Protection Devices
A number of devices are available to protect your system from the effects of power problems such as power surges, transients, and power failures. The
following subsections describe some of these devices.
Surge Protectors
Surge protectors are available in a variety of types and usually provide a level of protection commensurate with the cost of the device. Surge protectors
prevent overvoltage spikes, such as those that may occur during an electrical storm, from entering the system through the electrical outlet. Surge protectors
do not offer protection against brownouts, which occur when the voltage drops more than 20 percent below the normal AC line voltage level.
Line Conditioners
Line conditioners go beyond the overvoltage protection of surge protectors. Line conditioners keep a system's AC power source voltage at a fairly constant
level and provide protection from brownouts of short duration. Because of this added protection, line conditioners cost more than surge protectors—up to
several hundred dollars. However, these devices cannot protect against a complete loss of power.
Uninterruptible Power Supplies
UPS systems offer the most complete protection against variations in power because they use battery power to keep the system running when AC power is
unavailable or unusable. The battery is charged by the AC power while it is available so that once AC power is lost, the battery can provide power to the
system for a limited amount of time—from 15 minutes to an hour or so—depending on the UPS system.
UPS systems that provide only 5 minutes of battery power allow you to conduct shutdown of the system but are not intended to provide continued operation.
Use surge protectors with all UPS systems, and ensure that the UPS systems are UL safety approved.

Using the System Password Feature
NOTICE: The password features provide a basic level of security for the data on your system. If your data requires more security, it is your
responsibility to obtain and use additional forms of protection, such as data encryption programs.
Your system is shipped to you without the system password feature enabled. If system security is a concern, you should operate your system only with
system password protection.
You can assign a system password whenever you use the System Setup program. 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 just after the system starts.
To change an existing system password, you must know the password (see "Deleting or Changing an Existing System Password"). If you assign and later
forget a system password, a trained service technician must remove the system cover to change a jumper setting that disables the system password feature
(see "Disabling a Forgotten Password"). Note that this erases the setup password at the same time.
NOTICE: If you leave your 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, anyone can access the data stored on your hard drive.
Assigning a System Password
Before you can assign a system password, you must 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 Password Status option 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 on the system board, the setting shown is Disabled, and you cannot change or enter a new system password.
When no system password is 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, perform the following steps:
1.
Verify that the Password Status option is set to Unlocked.
2.
Highlight the System Password option and then 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 operation recognizes keys by their location on the keyboard without distinguishing between lowercase and uppercase
characters. For example, if you have an M in your password, the system recognizes either M or m as correct. Certain key combinations are not valid. If
you enter one of these combinations, the speaker emits a beep. To erase a character when entering your password, press the <Backspace> key 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 System Password option changes to Enabled. Your system password is now set. You can exit the System Setup program and begin using your
system.
NOTE: Password protection does not take effect until you restart the system by turning the system off and then on again.
Using Your System Password to Secure Your System
Whenever you turn on or reboot your system by pressing the <Ctrl><Alt><Del> key combination, the following prompt appears on the screen when the
Password Status option is set to Unlocked:
Type in the password and... -- press <ENTER> to leave password security enabled. -- press <CTRL><ENTER> to disable password security. Enter
password:
If the Password Status option is set to Locked, the following prompt appears:
Type the password and press <Enter>.
After you type the correct system password and press <Enter>, your system completes the startup sequence and you can use the keyboard or mouse to
operate your system as usual.
NOTE: If you have assigned a setup password (see "Using the Setup Password Feature"), the system accepts your setup password as an alternate
system password.
If a wrong or incomplete system password is entered, the following message appears:
** Incorrect password. **
Enter password:
If an incorrect or incomplete system password is entered again, the same message appears.
The third and subsequent times an incorrect or incomplete system password is entered, the system displays the following message:
** Incorrect password. **
Number of unsuccessful password attempts: 3
System halted! Must power down.
The number of unsuccessful attempts made to enter the correct system password can alert you to an unauthorized person attempting to use your system.
Even after your system is turned off and on, the previous message is displayed each time an incorrect or incomplete system 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, instead of pressing <Enter> to continue with the normal operation of
your system.
If you are asked to enter your setup password, you may need to contact your network administrator who has the setup password.
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 you want to assign a new password, continue
to step 6. If Not Enabled is not displayed for the System Password option, press the <Alt><b> key combination to restart the system, and then repeat
steps 2 through 5.
6.
To assign a new password, follow the procedure in "Assigning a System Password."
Using the Setup Password Feature
Your system is shipped to you without the setup password feature enabled. If system security is a concern, you should operate your system with the setup
password feature enabled.
You can assign a setup password whenever you use the System Setup program. After a setup password is assigned, only those who know the password
have full use of the System Setup program.
To change an existing setup password, you must know the setup password (see "Deleting or Changing an Existing Setup Password"). If you assign and later
forget a setup password, you cannot operate your system or change settings in the System Setup program until a trained service technician opens the system
chassis, changes the password jumper setting to disable the passwords, and erases the existing passwords. This procedure is described in the Installation
and Troubleshooting Guide.
Assigning a Setup Password
A setup password can be assigned (or changed) 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 emits a beep.
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.
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 the majority of the System Setup options. When you
start the System Setup program, the program prompts you to type the password.
If you do not enter the correct password in three tries, 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 via 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.
3.
If you want to assign a new setup password, perform the steps in "Assigning a Setup Password."
Disabling a Forgotten Password
If you forget your system or setup password, you cannot operate your system or change settings in the System Setup program until a trained service
technician opens the system chassis, changes the password jumper setting to disable the passwords, and erases the existing passwords. This procedure is
described in the Installation and Troubleshooting Guide.

charge indefinitely, your system continually refreshes each DRAM microprocessor in the system.
DVD
Abbreviation for digital versatile disk.
ECC
Abbreviation for error checking and correction.
EEPROM
Acronym for electrically erasable programmable read-only memory.
EISA
Acronym for Extended Industry-Standard Architecture, a 32-bit expansion-bus design. The expansion-card connectors in an EISA system are also compatible
with 8- or 16-bit ISA expansion cards.
To avoid a configuration conflict when installing an EISA expansion card, you must use the EISA Configuration Utility. This utility allows you to specify which
expansion slot contains the card and obtains information about the card's required system resources from a corresponding EISA configuration file.
EMC
Abbreviation for Electromagnetic Compatibility.
EMI
Abbreviation for electromagnetic interference.
ERA
Abbreviation for embedded remote access. ERA allows you to perform remote, or "out-of-band," server management on your network server using a DRAC III.
