I/O Ports and Connectors
Dell™ PowerEdge™ 500SC Systems User's Guide I/O Ports and Connectors
Serial and Parallel Connectors

Integrated Network Interface Controller Connector
I/O Ports and Connectors
The I/O ports and connectors on the back panel of the system are the gateways through which the system communicates with external devices, such as a
keyboard, mouse, printer, and monitor. Figure B-1 identifies the I/O ports and connectors for your system.
Figure B-1. I/O Ports and Connectors
Serial and Parallel Connectors
The integrated serial connector uses a 9-pin D-subminiature connector on the back panel. This port supports 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 connector (for example, COM1). The default designations of your
system's integrated serial connector is COM1. The integrated parallel connector uses a 25-pin D-subminiature connector on the system's back panel. This I/O port sends data in parallel format (where eight
data bits, or one byte, are sent simultaneously over eight separate lines in a single cable). The parallel connector is used primarily for printers.
Most software uses the term LPT (for line printer) plus a number to designate a parallel connector (for example, LPT1). The default designation of the system's
integrated parallel connector is LPT1.
Port designations are used, for example, in software installation procedures that include a step in which you identify the port to which a printer is attached,
thus telling the software where to send its output. (An incorrect designation prevents the printer from printing or causes scrambled print.)
Adding an Expansion Card Containing Serial or Parallel Connectors
The system has an autoconfiguration capability for the serial connectors. This feature lets you add an expansion card containing a serial connector that has
the same designation as one of the integrated ports, without having to reconfigure the card. When the system detects the duplicate serial connector 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 interrupt request (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 connector 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 connectors designated as COM1 and COM3, the corresponding integrated serial connector 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.
If you add an expansion card containing, for example a parallel connector configured as LPT1 (IRQ7, I/O address 378h), you must go into the System Setup program to remap the integrated parallel connector.
For general information on how your operating system handles serial and parallel connectors, and for more detailed command procedures, see your operating
system documentation.

Power Protection Devices
A number of devices are available that protect against 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 voltage spikes, such as those caused during an electrical storm, from entering a system through the electrical outlet. Surge protectors, however, 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, therefore, can handle brownouts. 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
lost. The battery is charged by the AC power while it is available, so 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 range in price from a few hundred dollars to several thousand dollars, with the more expensive units allowing you to run larger systems for a
longer period of time when AC power is lost. UPS systems that provide only 5 minutes of battery power let you conduct an orderly shutdown of the system,
but are not intended to provide continued operation. Surge protectors should be used with all UPS systems, and the UPS system should be UL safetyapproved.

Using the System Password Feature
NOTICE: The password features provide a basic level of security for the data on your system. However, they are not foolproof. 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 boots.
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, you need to be able to remove the system cover to change a jumper setting that disables the system password feature (see
"Disabling a Forgotten Password"). Note that you erase 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. When the system password feature is disabled by a
jumper setting on the system board, the setting shown is Disabled by Jumper. You cannot change or enter a new system password if either of these settings
is displayed.
When no system password is assigned and the password jumper on the system board is in the enabled position (its default), the setting shown for the
System Password option is Not Enabled. Only when this option is set to Not Enabled can you assign a system password, using the following procedure:
1.
Verify that the Password Status option is set to Unlocked.
2.
Highlight the System Password option and then press the left- or right-arrow key.
3.
Type your new system password.
You can use up to seven characters in your password.
As you press each character key (or the spacebar key 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 <Tab> or <Shift><Tab> to move to another field, or press <Esc> at
any time prior to completing step 5.
4.
Press <Enter>.
If the new system password is less than seven characters, the whole field fills with placeholders. Then the option heading changes to Verify Password,
followed by another empty seven-character field in square brackets.
5.
To confirm your password, type it a second time and press <Enter>.
The password setting changes to Enabled. Your system password is now set; you can exit the System Setup program and begin using your system.
Note, however, that password protection does not take effect until you reboot 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 boots 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 System Password and Setup Password to further protect your system from
unauthorized changes.
Deleting or Changing an Existing System Password
1.
Enter the System Setup program by pressing <F2>.
2.
Select the System Security screen field to verify that the Password Status option is set to Unlocked.
3.
Reboot your system to force it to prompt you for a system password.
4.
When prompted, type the system password.
5.
Press <Ctrl><Enter> to disable the existing system password, instead of pressing <Enter> to continue with the normal operation of your system.
6.
Confirm that Not Enabled is displayed for the System Password option of the System Setup program.
If Not Enabled appears 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 reboot the system, and then repeat
steps 4 through 6.
7.
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 setup
password protection.
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 Appendix B of 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 left- or right-arrow 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 (rebooting 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 exceptions:
l
You can still modify the Date, Time, Keyboard Num Lock, and Speaker options.
l
If System Password is not 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 Setup Password to protect the system password from unauthorized changes.
Deleting or Changing an Existing Setup Password
To delete or change an existing setup password, perform the following steps:
1.
2.
Enter the System Setup program and select the System Security screen option.
Highlight the Setup Password option and press the left- or right-arrow key to delete 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 Appendix A of the Installation and Troubleshooting Guide.

switches are always toggle switches, with an ON position and an OFF position.
directory
Directories help keep related files organized on a disk in a hierarchical, "inverted tree" structure. Each disk has a "root" directory; for example, a C:\> prompt
normally indicates that you are at the root directory of hard-disk drive C. Additional directories that branch off of the root directory are called subdirectories.
Subdirectories may contain additional directories branching off of them.
DMA
Abbreviation for direct memory access. A DMA channel allows certain types of data transfer between RAM and a device to bypass the microprocessor.
DMI
Abbreviation for Desktop Management Interface. DMI enables the management of your system's software and hardware. DMI collects information about the
system's components, such as the operating system, memory, peripherals, expansion cards, and asset tag. Information about the system's components is
displayed as a MIF file or through the Dell Inspector program.
DPMS
Abbreviation for Display Power Management Signaling. A standard developed by the Video Electronics Standards Association (VESA®) that defines the
hardware signals sent by a video controller to activate power management states in a monitor. A monitor is said to be DPMS-compliant when it is designed to
enter a power management state after receiving the appropriate signal from a system's video controller.
DRAC
Acronym for Dell OpenManage Remote Assistant Card.
DRAM
Abbreviation for dynamic random-access memory. A system's RAM is usually made up entirely of DRAM chips. Because DRAM chips cannot store an electrical
charge indefinitely, your system continually refreshes each DRAM microprocessor in the system.
drive-type number
Your system can recognize a number of specific hard-disk drives. Each is assigned a drive-type number that is stored in NVRAM. The hard-disk drive(s) specified
in your system's System Setup program must match the actual drive(s) installed in the system. The System Setup program also allows you to specify physical
parameters (logical cylinders, logical heads, cylinder number, and logical sectors per pack) for drives not included in the table of drive types stored in NVRAM.
