About RAID Configurations This section provides an overview of the RAID configuration you may have selected when you purchased your computer. There are several RAID configurations available in the computer industry for different types of uses. Your Dell Precicion computer supports RAID level 0, RAID level 1, RAID level 5, or RAID level 10, also known as RAID level 1+0.
RAID Level 0 NOTICE: Because a RAID level 0 configuration provides no data redundancy, a failure of one drive results in the loss of all data. To protect your data when using a RAID level 0 configuration, perform regular backups. RAID level 0 uses a storage technique known as data striping to provide a high data access rate. Data striping is a method of writing consecutive segments, or stripes, of data sequentially across the physical drive(s) to create a large virtual drive.
serial ATA RAID configured for RAID level 1 segment 1 segment 1 duplicated segment 2 segment 2 duplicated segment 3 segment 3 duplicated segment 4 segment 4 duplicated segment 5 segment 5 duplicated segment 6 segment 6 duplicated hard drive 1 hard drive 2 If a drive failure occurs, subsequent read and write operations are directed to the surviving drive. A replacement drive can then be rebuilt using the data from the surviving drive.
serial ATA RAID configured for RAID level 5 segment 1 segment 1 striped across at least 3 drives segment 2 segment 2 striped across at least 3 drives segment 3 segment 3 striped across at least 3 drives segment 4 segment 4 striped across at least 3 drives segment 5 segment 5 striped across at least 3 drives segment 6 segment 6 striped across at least 3 drives hard drive 1 hard drives 2, 3 (and optionally, 4) If a drive failure occurs, subsequent read and write operations are directed to the s
serial ATA RAID configured for RAID level 10 segment 1 segment 1 striped across 4 drives segment 2 segment 2 striped across 4 drives segment 3 segment 3 striped across 4 drives segment 4 segment 4 striped across 4 drives segment 5 segment 5 striped across 4 drives segment 6 segment 6 striped across 4 drives hard drive 1 hard drives 2, 3, and 4 If a drive failure occurs, subsequent read and write operations are directed to the surviving drives.

Setting Up Your Computer
Securing Your Computer Chassis Intrusion Detection NOTE: When the administrator password is enabled, you must know the administrator password before you can reset the Chassis Intrusion setting. The Chassis Intrusion Detection feature detects when the computer chassis is or has been opened and alerts the user. The following Chassis Intrusion settings are available in System Setup: • Off — The Chassis Intrusion dectection feature is disabled. If the computer cover is opened, no action is taken.
Smart Cards and Fingerprint Readers NOTE: The smart card feature may not be available on your computer. Smart cards are portable credit-card shaped devices with internal integrated circuits. Using smart cards can improve system security by combining something a user has (the smart card) with something only the user should know (a PIN) to provide more secure user-authentication than passwords alone. A fingerprint reader is a strip sensor located on a peripheral device for your computer.
Use the User Accounts option in the Control Panel in the Microsoft Windows operating system to create user accounts or to change passwords. Once you create a user password, you must enter it each time you turn on or unlock your computer. If a valid password is not entered within two minutes, the computer returns to its previous operating state. For more information, see your Windows documentation. About Passwords NOTICE: Passwords provide a high level of security for data in your computer or hard drive.
Using a Primary (System) Password The primary password protects your computer from unauthorized access. If a primary password is set, you must enter the password when your computer starts. If a valid password is not entered within two minutess, the computer returns to its previous operating state. NOTICE: If you disable the administrator password, the primary password is also disabled. To add or change passwords, access User Accounts from the Control Panel.
If you forget the primary password and do not have an administrator password assigned, or if you have both a primary and an administrator password assigned, but forget them both, contact your system administrator or contact Dell (see "Contacting Dell" on page 269). Using a Hard Drive Password The hard drive password helps protect the data on your hard drive from unauthorized access.
Trusted Platform Module (TPM) NOTE: The TPM feature supports encryption only if the operating system supports TPM. For more information, see the TPM software documentation and the help files that came with the software. TPM is a hardware-based security feature that can be used to create and manage computer-generated encryption keys. When combined with security software, TPM enhances existing network and computer security by enabling features such as file protection capabilities and protected e-mail.
8 Press . 9 Press the left- and right-arrow keys to highlight Save/Exit, and then press to exit System Setup and restart your computer. NOTE: If prompted to IGNORE or MODIFY the changes to the TPM setting, select MODIFY, and then press . 10 Use the Embassy Security Center to manage the TPM security feature.
If Your Computer Is Lost or Stolen • Call a law enforcement agency to report the lost or stolen computer. Include the Service Tag in your description of the computer. Ask that a case number be assigned and write down the number, along with the name, address, and phone number of the law enforcement agency. If possible, obtain the name of the investigating officer. NOTE: If you know where the computer was lost or stolen, call a law enforcement agency in that area.
