Power Management
Your computer can be set to use less power when you are not working. You control the power usage through the operating system installed on your computer
and certain option settings in system setup. These periods of reduced power are called "sleep modes."
lStandby. In this sleep mode, power is reduced or turned off for most components, including the cooling fans. However, system memory remains active.
lHibernate. This sleep mode reduces power consumption to a minimum by writing all data in system memory to a hard drive and then removing system
power. Waking up from this mode restarts the computer, and the memory contents are restored. Operation then resumes where the computer left off
when it entered the hibernation mode.
lShutdown. This sleep mode removes all power from the computer except a small auxiliary amount. As long as the computer remains connected to an
electrical outlet, it can be automatically or remotely started. For example, the Auto Power On option in system setup allows the computer to
automatically start at a specified time. Also, your network administrator can remotely start your computer using a power management event such as
Remote Wake Up.
The following table lists the sleep modes and the methods you can use to wake the computer from each mode.

DDR2 Memory Overview
Addressing Memory With 4-GB Configurations
Removing Memory
Replacing/Adding Additional Memory
For information on the type of memory supported by your computer, see the "Memory" section of the specifications for your computer:
lMini Tower Computer Specifications
lDesktop Computer Specifications
DDR2 Memory Overview
Dual-channel DDR2 memory modules should be installed in pairs of matched memory size. If the DDR2 memory modules are not installed with the same amount
of memory in each channel, the computer will continue to operate, but with a slight reduction in performance. See the label in the upper-right corner of the
module to determine the module's capacity.
The recommended memory configurations are:
lA pair of matched memory modules installed in connectors DIMM1 and DIMM2
or
lA memory module installed in connector DIMM1
Be sure to install a single memory module in DIMM1, the connector closer to the processor, before you install a module in the other connector.
Addressing Memory With 4-GB Configurations
This computer supports a maximum of 4 GB of memory when you use two 2-GB DIMMs. Current operating systems, such as Microsoft®Windows®XP, can only
use a maximum of 4 GB of address space; however, the amount of memory available to the operating system is less than 4 GB. Certain components within the
computer require address space in the 4-GB range. Any address space reserved for these components cannot be used by computer memory.
If you use a 64-bit operating system, the entire memory range is available to the operating system.
The following components require memory address space:
lSystem ROM
lAPIC(s)
lIntegrated PCI devices, such as network connectors and SCSI controllers
lPCI cards
lGraphics card
lPCI Express cards (if applicable)
At start-up, the BIOS identifies the components that require address space. The BIOS dynamically calculates the amount of reserved address space required.
The BIOS then subtracts the reserved address space from 4 GB to determine the amount of usable space.
lIf the total installed computer memory is less than the usable space, all installed computer memory is available for use only by the operating system.
lIf the total installed computer memory is equal to or greater than the usable address space, a small portion of installed memory is available for use by
the operating system.
NOTE: Always install DDR2 memory modules in the order indicated on the system board.
NOTICE: Do not install ECC memory modules. Doing so may cause the system not to boot or affect performance.
Removing Memory
1. Follow the procedures in "Before You Begin."
2. Carefully press out the securing clip at each end of the memory module connector.
3. Remove the memory module.
Replacing/Adding Additional Memory
1. Follow the procedures in "Before You Begin."
2. Press out the securing clip at each end of the memory module connector.

The amount of system memory has changed.
Strike the F1 key to continue, F2 to run the setup utility
7. Press <F2> to enter system setup and check the value for System Memory.
The computer should have changed the value of System Memory to reflect the newly installed memory. Verify the new total. If it is correct, skip to
step9.
8. If the memory total is incorrect, turn off and disconnect your computer and devices from their electrical outlets. Open the computer cover and check the
installed memory modules to ensure that they are seated properly in their sockets. Then repeat steps 5, 6, and 7.
9. When the System Memory total is correct, press <Esc> to exit system setup.

Drives
Drives
Your computer supports:
lTwo serial ATA hard drives
lTwo floppy or optional Zip drives
lTwo CD or DVD drives
General Installation Guidelines
Connect CD/DVD drives to the connector labeled "IDE" on the system board. Serial ATA hard drives should be connected to the connectors labeled "SATA0" or
"SATA2" on the system board.
IDE Drive Addressing
When you connect two IDE devices to a single IDE interface cable and configure them for the cable select setting, the device attached to the last connector on
the interface cable is the master or boot device (drive 0), and the device attached to the middle connector on the interface cable is the slave device (drive 1).
See the drive documentation in your upgrade kit for information on configuring devices for the cable select setting.
Connecting Drive Cables
When you install a drive, you connect two cables—a DC power cable and a data cable—to the back of the drive and to the system board.
Drive Interface Connectors
NOTE: Due to the limited number of drive bays and IDE controllers on this computer, you will not be able to connect all supported devices at once.
1
CD/DVD drive
2
floppy drive
3

IDE Drive Connector
Serial ATA
Connector
Most interface connectors are keyed for correct insertion; that is, a notch or a missing pin on one connector matches a tab or a filled-in hole on the other
connector. Keyed connectors ensure that the pin-1 wire in the cable (indicated by the colored stripe along one edge of the IDE cable—serial ATA cables do not
use a colored stripe) goes to the pin-1 end of the connector. The pin-1 end of a connector on a board or a card is usually indicated by a silk-screened "1"
printed directly on the board or card.
Power Cable Connectors
Connecting and Disconnecting Drive Cables
When removing an IDE drive data cable, grasp the colored pull-tab and pull until the connector detaches.
When connecting and disconnecting a serial ATA data cable, hold the cable by the black connector at each end.
Like IDE connectors, the serial ATA interface connectors are keyed for correct insertion; that is, a notch or a missing pin on one connector matches a tab or a
filled-in hole on the other connector.

FCC Notices (U.S. Only)
Dell™OptiPlex™210LUser'sGuide
Electromagnetic Interference (EMI) is any signal or emission, radiated in free space or conducted along power or signal leads, that endangers the functioning
of a radio navigation or other safety service or seriously degrades, obstructs, or repeatedly interrupts a licensed radio communications service. Radio
communications services include but are not limited to AM/FM commercial broadcast, television, cellular services, radar, air-traffic control, pager, and Personal
Communication Services (PCS). These licensed services, along with unintentional radiators such as digital devices, including computer systems, contribute to
the electromagnetic environment.
Electromagnetic Compatibility (EMC) is the ability of items of electronic equipment to function properly together in the electronic environment. While this
computer system has been designed and determined to be compliant with regulatory agency limits for EMI, there is no guarantee that interference will not
occur in a particular installation. If this equipment does cause interference with radio communications services, which can be determined by turning the
equipment off and on, you are encouraged to try to correct the interference by one or more of the following measures:
lReorient the receiving antenna.
lRelocate the computer with respect to the receiver.
lMove the computer away from the receiver.
lPlug the computer into a different outlet so that the computer and the receiver are on different branch circuits.
If necessary, consult a Dell Technical Support representative or an experienced radio/television technician for additional suggestions.
For additional regulatory information, see the Product Information Guide that came with your computer.
Dell™computersystemsaredesigned,tested,andclassifiedfortheirintendedelectromagneticenvironment.Theseelectromagneticenvironment
classifications generally refer to the following harmonized definitions:
lClass A is typically for business or industrial environments.
lClass B is typically for residential environments.
Information Technology Equipment (ITE), including peripherals, expansion cards, printers, input/output (I/O) devices, monitors, and so on, that are integrated
into or connected to the system should match the electromagnetic environment classification of the computer system.
A Notice About Shielded Signal Cables: Use only shielded cables for connecting peripherals to any Dell device to reduce the possibility of interference
with radio communications services. Using shielded cables ensures that you maintain the appropriate EMC classification for the intended environment.
For parallel printers, a cable is available from Dell. If you prefer, you can order a cable from Dell on the World Wide Web at
accessories.us.dell.com/sna/category.asp?category_id=4117.
Most Dell computer systems are classified for Class B environments. However, the inclusion of certain options can change the rating of some configurations to
Class A. To determine the electromagnetic classification for your system or device, see the following sections specific for each regulatory agency. Each section
provides country-specific EMC/EMI or product safety information.
FCC Notices (U.S. Only)
Most Dell computer systems are classified by the Federal Communications Commission (FCC) as Class B digital devices. To determine which classification
applies to your computer system, examine all FCC registration labels located on the bottom, side, or back panel of your computer, on card-mounting brackets,
and on the cards themselves. If any one of the labels carries a Class A rating, your entire system is considered to be a Class A digital device. If all labels carry
an FCC Class B rating as distinguished by either an FCC ID number or the FCC logo, ( ), your system is considered to be a Class B digital device.
Once you have determined your system's FCC classification, read the appropriate FCC notice. Note that FCC regulations provide that changes or modifications
not expressly approved by Dell could void your authority to operate this equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
lThis device may not cause harmful interference.
lThis device must accept any interference received, including interference that may cause undesired operation.
Class A
This equipment has been tested and found to comply with the limits for a Class A digital device pursuant to Part 15 of the FCC Rules. These limits are designed
to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses,
and can radiate radio frequency energy and, if not installed and used in accordance with the manufacturer's instruction manual, may cause harmful
interference with radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case you will be
required to correct the interference at your own expense.
Class B
This equipment has been tested and found to comply with the limits for a Class B digital device pursuant to Part 15 of the FCC Rules. These limits are designed
to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency
energy and, if not installed and used in accordance with the manufacturer's instruction manual, may cause interference with radio communications. However,
there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and on, you are encouraged to try to correct the interference by one or more of the following
measures:
lReorient or relocate the receiving antenna.
lIncrease the separation between the equipment and the receiver.
lConnect the equipment into an outlet on a circuit different from that to which the receiver is connected.
lConsult the dealer or an experienced radio/television technician for help.

Drivers
What Is a Driver?
A driver is a program that controls a device such as a printer, mouse, or keyboard. All devices require a driver program.
A driver acts like a translator between the device and any other programs that use the device. Each device has its own set of specialized commands that only
its driver recognizes.
Dell ships your computer to you with required drivers already installed—no further installation or configuration is needed.
Many drivers, such as the keyboard driver, come with your Microsoft Windows operating system. You may need to install drivers if you:
lUpgrade your operating system.
lReinstall your operating system.
lConnect or install a new device.
Identifying Drivers
If you experience a problem with any device, identify whether the driver is the source of your problem and, if necessary, update the driver.

Drives
Your computer supports:
lOne serial ATA hard drive
lOne optional ATA hard drive
lOne optional floppy drive
lOne optional CD or DVD drive
General Installation Guidelines
Connect CD/DVD drives to the connector labeled "IDE" on the system board. Serial ATA hard drives should be connected to the connectors labeled "SATA0" or
"SATA2" on the system board.
Connecting Drive Cables
When you install a drive, you connect two cables—a DC power cable and a data cable—to the back of the drive and to the system board.
Drive Interface Connectors

IDE Drive Connector
Serial ATA Connector
1
colored stripe on IDE cable
2
interface cable connector
3
interface connector
Most interface connectors are keyed for correct insertion; that is, a notch or a missing pin on one connector matches a tab or a filled-in hole on the other
connector. Keyed connectors ensure that the pin-1 wire in the cable (indicated by the colored stripe along one edge of the IDE cable—serial ATA cables do not
use a colored stripe) goes to the pin-1 end of the connector. The pin-1 end of a connector on a board or a card is usually indicated by a silk-screened "1"
printed directly on the board or card.
Power Cable Connectors
Connecting and Disconnecting Drive Cables
When removing an IDE drive data cable, grasp the colored pull-tab and pull until the connector detaches.
When connecting and disconnecting a serial ATA data cable, hold the cable by the black connector at each end.
Like IDE connectors, the serial ATA interface connectors are keyed for correct insertion; that is, a notch or a missing pin on one connector matches a tab or a
filled-in hole on the other connector.
CD/DVD Drive
Removing a CD/DVD Drive
1. Follow the procedures in "Before You Begin."
2. Pull up on the drive release latch and slide the drive towards the back of the computer. Then, lift up to remove the drive from the computer.
