Replacing the Bezel CAUTION: When reinstalling the front bezel, carefully align the bezel to avoid damaging the connector on the back which operates the indicator lights on the front of the bezel. 1. Align the four notches and the connector on the back of the bezel with the four posts and connector on the front of the system. 2. Gently press the bezel onto the front of the computer until it snaps into place. Front-Panel Features Figure 1-3 shows the major features at the front of the computer.
Figure 1-4. Bezel Indicators Control-Panel Indicators The indicators on the computer's control panel described in Table 1-1 are shown in Figure 1-5: Table 1-1.
Back-Panel Features Figure 1-6 shows the back-panel features on the computer. Figure 1-6. Back-Panel Features When connecting external devices to your system, follow these guidelines: l Always attach external devices while your system is turned off and the AC power cords are unplugged.
system unless the documentation for the device specifies otherwise. (If the system does not seem to recognize the device, try turning on the system before turning on the device.) l Check the documentation that accompanied the device for specific installation and configuration instructions. For example, most devices must be connected to a particular connector to operate properly. Also, external devices usually require you to install device drivers before they will work.
Power Protection Devices A number of devices are available that protect against potential 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.

They provide access to various utilities which you may use to configure your system.
If your system is already on, reboot it. 2. Wait until the system tests are completed. The EFI Boot Manager screen appears. 3. From the EFI Boot Manager main menu, select Utilities. 4. From the Utilities Options menu, select Dell Utilities.
Back to Contents Page Using the System Setup Program Dell™ PowerEdge™ 7150 Systems User's Guide Entering the System Setup Program System Setup Screens Using the Password Features Disabling a Forgotten Password You can use the system setup program as follows: l To change the system configuration information after you add, change, or remove hardware in your system l To set or change user-selectable options—for example, the time or date on your system l To configure integrated devices in your system Af
System Setup Screens The system setup screens display the current setup and configuration information for your system. You can select the following five primary screens: l Main — displays the BIOS version, microprocessor type, and default system setup screen language. You can also set the system time and date and processor retest option from this screen.
NOTE: See the section "Using the Password Features" for instructions on assigning a password and using or changing an existing password. See the section, "Disabling a Forgotten Password" for instructions on disabling a forgotten password. The Security Screen also allows you to enable and configure the Secure Mode option. When the system is in Secure Mode, most input and output devices are disabled until you enter the user password.
Using the Supervisor Password Feature When the supervisor password is enabled, the system prompts you for the supervisor password whenever you enter the system setup program. If system configuration security is a concern, you should operate your system with supervisor password protection. Once the supervisor password is assigned, only those who know the password have full use of the system setup program, including the Security screen.

Video resolution—640 x 480, for example—is expressed as the number of pixels across by the number of pixels up and down. POST Acronym for power-on self-test. Before the operating system loads when you turn on your system, the POST tests various system components such as RAM, the disk drives, and the keyboard.
A read-only file is one that you are prohibited from editing or deleting. A file can have read-only status if: Its read-only attribute is enabled. It resides on a physically write-protected diskette. It is located on a network in a directory to which the system administrator has assigned read-only rights to you. refresh rate The frequency, measured in Hz, at which the screen's horizontal lines are recharged. A monitor's refresh rate is also referred to as its vertical frequency.
As the main circuit board, the system board usually contains most of your system's integral components, such as the following: l Microprocessor l RAM l Expansion-card connectors l Controllers for standard peripheral devices such as the keyboard l Various ROM chips Frequently used synonyms for system board are motherboard and logic board. system diskette System diskette is a synonym for bootable diskette. system memory System memory is a synonym for RAM.
colors that a program can display depends on the capabilities of the monitor, the video driver, and the amount of memory installed for the video adapter.
