Accessing System Features During Startup
Front-Panel Features and Indicators
Back-Panel Features and Indicators
This section describes the physical, firmware, and software interface features that provide and ensure the essential functioning of your system. The physical connectors on your system's front and back panels provide convenient connectivity and system expansion capability. The system firmware, applications, and operating systems monitor the system and component status and alert you when a problem arises. System conditions can be reported by any of the following:
This section describes each type of message, lists the possible causes, and provides steps to resolve any problems indicated by a message. The system indicators and features are illustrated in this section.
|
CAUTION: The Product Information Guide provides important safety and regulatory information. Warranty information may be included within this document or as a separate document. |
|
NOTE: Always check for updates on support.dell.com and read the updates first because they often supersede information in other documents. |
Table 1-1 describes keystrokes that may be entered during startup to access system features. If your operating system begins to load before you enter the keystroke, allow the system to finish booting, and then restart your system and try again.
Table 1-1. Keystrokes for Accessing System Features
|
Keystroke |
Description |
|---|---|
<F2> | Enters the System Setup program. See Using the System Setup Program. |
<F10> | Enters the Utility Partition main menu to access the System Diagnostics program. See Running the System Diagnostics. |
<F11> | Enters the boot mode selection screen, allowing you to choose a boot device. |
<F12> | Enters PXE boot. |
<Ctrl+E> | Enters the Baseboard Management Controller (BMC) Management Utility, which allows access to the system event log (SEL) and configuration of the remote access controller (RAC) card. See the BMC User's Guide for more information on setup and use of BMC. |
<Ctrl+R> | Enters the PERC boot utility. See your PERC adapter User's Guide for more information. |
<Ctrl+C> | If a SAS controller is installed, this keystroke enters the SAS Configuration Utility. See your SAS adapter User's Guide for more information. |
<Ctrl+S> | Option is displayed if you have PXE support enabled through the System Setup Program (see Integrated Devices Screen), or iSCSI boot enabled. This keystroke allows you to configure NIC settings for PXE boot. For more information, see the documentation for the integrated NIC. |

Table 1-3 lists the drive indicator patterns for hard drives connected to a RAID-enabled controller card such as a PERC6i card. Different patterns are displayed as drive events occur in the system. For example, if a hard drive fails, the "drive failed" pattern appears. After the drive is selected for removal, the "drive being prepared for removal" pattern appears, followed by the "drive ready for insertion or removal" pattern. After the replacement drive is installed, the "drive being prepared for operation" pattern appears, followed by the "drive online" pattern.

Table 1-6. NIC Indicator Codes
The system's control panel LCD provides status messages to signify when the system is operating correctly or when the system needs attention.
The LCD lights blue to indicate a normal operating condition, and lights amber to indicate an error condition. The LCD scrolls a message that includes a status code followed by descriptive text. Table 1-7 lists the LCD status messages that can occur and the probable cause for each message. The LCD messages refer to events recorded in the System Event Log (SEL). For information on the SEL and configuring system management settings, see the systems management software documentation.

CAUTION: Only trained service technicians are authorized to remove the system cover and access any of the components inside the system. See your Product Information Guide for complete information about safety precautions, working inside the computer, and protecting against electrostatic discharge. |
|
NOTE: If your system fails to boot, press the System ID button for at least five seconds until an error code appears on the LCD. Record the code, then see Getting Help. |

The code and text on the LCD can often specify a very precise fault condition that is easily corrected. For example, if the code E0708 PROC_1_Presence appears, you know that a microprocessor is not installed in socket 1.
In contrast, you might be able to determine the problem if multiple related errors occur. For example, if you receive a series of messages indicating multiple voltage faults, you might determine that the problem is a failing power supply.
For faults associated with sensors, such as temperature, voltage, fans, and so on, the LCD message is automatically removed when that sensor returns to a normal state. For example, if temperature for a component goes out of range, the LCD displays the fault; when the temperature returns to the acceptable range, the message is removed from the LCD. For other faults, you must take action to remove the message from the display:
Any of these actions will remove fault messages, and return the status indicators and LCD colors to the normal state. Messages will reappear under the following conditions:
System messages appear on the screen to notify you of a possible problem with the system. Table 1-8 lists the system messages that can occur and the probable cause and corrective action for each message.
|
NOTE: If you receive a system message that is not listed in Table 1-8, check the documentation for the application that is running when the message appears or the operating system's documentation for an explanation of the message and recommended action. |
|
CAUTION: Only trained service technicians are authorized to remove the system cover and access any of the components inside the system. See your Product Information Guide for complete information about safety precautions, working inside the computer, and protecting against electrostatic discharge. |

A warning message alerts you to a possible problem and prompts you to respond before the system continues a task. For example, before you format a diskette, a message will warn you that you may lose all data on the diskette. Warning messages usually interrupt the task and require you to respond by typing y (yes) or n (no).
|
NOTE: Warning messages are generated by either the application or the operating system. For more information, see the documentation that accompanied the operating system or application. |
The system diagnostic utilities produce messages from diagnostic tests run on your system. See Running the System Diagnostics for more information about system diagnostics.
Systems management software generates alert messages for your system. Alert messages include information, status, warning, and failure messages for drive, temperature, fan, and power conditions. For more information, see the systems management software documentation.
