10 Introduction

Indicators, Messages, and Codes

The system, applications, and operating systems can identify problems and alert you to them. Any of the following can indicate when the system is not operating properly:

• System indicators

• System messages

• Beep codes

• Warning messages

• Diagnostics messages

• Alert messages

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.

Front-Panel Indicators and Features

Figure 2-1 shows the front-panel indicators for the system status and hard drive activity. Table 2-1 details the conditions associated with each indicator code.

drives are in use.

12 Indicators, Messages, and Codes

Table 2-1. Front-Panel Indicator Codes (continued)

LED Indicator Description

Hard-drive status indicator The green hard-drive status indicator lights up when the drive

is ready and is functioning normally. The status indicator is off when the drive is absent and is not configured as part of a RAID or non-RAID volume or cannot be detected by the operating system or RAID controller.

The green status indicator blinks when a volume of which the drive is a member is rebuilding.

The amber status indicator blinks when a fault occurs with the drive.

NIC1 and NIC2 link indicators The indicators for the two integrated network adapters light

green if the network adapters are connected to the network.

The indicators flash green when data is being transmitted.

Power indicator The green indicator flashes if AC power is available to the

system, but the system is not powered on.

The green indicator is on when the system is powered on.

If the system is not connected to AC power, the green indicator is off.

• The power button provides the ability to soft switch the power cycling to the system.

• The two system identification buttons on the front and back panels can be used to locate a particular system within a rack. When one of these buttons is pushed or the system management software is used to identify the system, the blue system status indicators on the front and back of the system blink. (To stop the indicator from blinking press one of the identification buttons a second time, or use the systems management software.)

The front panel also incorporates a USB connector that is accessible when the bezel is removed. See Figure 2-4.

Back-Panel Indicators and Features

Figure 2-2 shows the back-panel indicators and features and Figure 2-3 shows the indicators for the integrated network adapters. Table 2-2 details the conditions associated with each back-panel indicator code.

System Beep Codes

If an error that cannot be reported on the screen occurs during POST, the system may emit a series of beeps that identifies the problem.

NOTE: If the system boots without a keyboard, mouse, or monitor attached, the system does not issue

beep codes related to those peripherals.

If a beep code is emitted, write down the series of beeps and then look it up in Table 2-4. If you are unable to resolve the problem by looking up the meaning of the beep code, use system diagnostics to identify the possible cause. If you are still unable to resolve the problem, see "Getting Help."

Warning Messages

A warning message alerts you to a possible problem and prompts you to respond before the system

www.dell.com | support.dell.com

continues a task. For example, before you format a hard drive, a message warns that you may lose all data on the drive. Warning messages usually interrupt the task and require you to respond by typing

(yes) or n (no).

NOTE: Warning messages are generated by either the application or the operating system. For more

information, see "Finding Software Solutions" and the documentation that accompanied the operating system or application.

Diagnostics Messages

When you run system diagnostics, an error message may result. Diagnostic error messages are not covered in this section. Record the message on a copy of the Diagnostics Checklist in "Getting Help," and then follow the instructions in that section for obtaining technical assistance.

Alert Messages

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 on your NAS system’s

CD.

Finding Software Solutions

Software problems can be caused by:

• Improper installation or configuration of an application

• Application conflicts

• Input errors

• Interrupt assignment conflicts

Ensure that you are installing the software application according to the software manufacturer’s recommended procedures. If a problem occurs after you install the software, you might need to troubleshoot your software application and your system.

See the documentation that accompanied the software or contact the software manufacturer for detailed troubleshooting information.

NOTE: If all of the system diagnostic tests complete successfully, then the problem is most likely caused

by the software and not the hardware.

Before You Begin

• Scan the software media with antivirus software.

• Read the software documentation before you run the installation utility.

• Be prepared to respond to prompts from the installation utility.

The installation utility may require you to enter information about your system, such as how the operating system is configured, and the type of peripherals that are connected to the system. Have this information available before running the installation utility.

Troubleshooting Errors and Conflicts

While configuring and running software, problems might occur that are caused by input errors, application conflicts, and/or IRQ assignment conflicts. The problems are sometimes indicated by error messages.

Finding Software Solutions 27

Error messages are generated by system hardware or software. "Indicators, Messages, and Codes" provides information about error messages that are hardware-based. If you receive an error message that is not listed, see your operating system or software program documentation for troubleshooting information.

Input Errors

Pressing a specific key or set of keys at the wrong time may produce unexpected results. See the documentation that came with the software application to ensure that the values or characters you are entering are valid.

Ensure that your operating system is configured properly to run the application. Remember that whenever you change the parameters of the operating system, the changes can conflict with an

www.dell.com | support.dell.com

application’s operating requirements. After you configure the operating system, you may need to reinstall or reconfigure a software application so that it can run properly in its new environment.

Application Conflicts

Some applications can leave unnecessary files or data behind after they are deleted from your system. Device drivers can also create application errors. If application errors occur, see your application device driver or operating system documentation for troubleshooting information.

IRQ Assignment Conflicts

Most PCI devices can share an IRQ with another device, but they cannot use an IRQ simultaneously. To avoid this type of conflict, see the documentation for each PCI device for specific IRQ requirements.
