Overview

This section describes beep codes and system error messages that can occur during system start-up or, in the case of some failures, during normal system operation. The tables in this section list faults that can cause a beep code or system error message to occur and the probable causes of the fault in each case. This section also suggests actions you can take to resolve problems indicated by a message.

If a faulty system does not emit beep codes or display system error messages to indicate a failure, you should run the appropriate tests in the Dell Diagnostics to help isolate the source of the problem. See "Running the Dell Diagnostics" in the Dell PowerEdge 2400 Systems Installation and Troubleshooting Guide.

Several different types of messages can indicate when the system is not functioning properly:

System messages
System beep codes
Warning messages
Diagnostics messages
Alert messages
SCSI hard-disk drive indicator codes

System Messages

System messages alert you to a possible operating system problem or to a conflict between the software and hardware. Table 1 lists the system error messages that can occur and the probable cause for each message.

If the table does not lead to the source of the problem, run the appropriate tests in the Dell Diagnostics (see the Installation and Troubleshooting Guide) to assist in troubleshooting the problem.

NOTE: If you receive a system message that is not listed in Table 1, check the documentation for the application program that is running when the message appears and/or the operating system documentation for an explanation of the message and recommended action.

System Beep Codes

When an error that cannot be reported on the monitor occurs during a boot routine, the computer may emit a series of beeps that identify the problem. The beep code is a pattern of sounds; for example, one beep followed by a second beep and then a burst of three beeps (code 1-1-3) means that the computer was unable to read the data in nonvolatile random-access memory (NVRAM). This information is valuable to the Dell technical support representative if you need to call for technical assistance.

When a beep code is emitted, record it on a copy of the Diagnostics Checklist, and then look it up in Table 2. If you are unable to resolve the problem by looking up the meaning of the beep code, use the Dell Diagnostics to identify a more serious cause. See "Running the Dell Diagnostics" in the Dell PowerEdge 2400 Systems Installation and Troubleshooting Guide.

Warning Messages

A warning message alerts you to a possible problem and asks you to take corrective action before the system continues a task. For example, before you format a diskette, a message may warn you that you may lose all data on the diskette, as a way to protect against inadvertently erasing or writing over the data. These warning messages usually interrupt the procedure and require you to respond by typing y (yes) or n (no).

NOTE: Warning messages are generated by either the application program or the operating system. See your Installation and Troubleshooting Guide and the documentation that accompanied the operating system and application program for more information on warning messages.

Diagnostics Messages

When you run a test group or subtest in the Dell Diagnostics, an error message may result. These particular error messages are not covered in this section. Record the message on a copy of the Diagnostics Checklist, and then follow the instructions in that section for obtaining technical assistance.

Alert Log Messages From the Dell OpenManage™ HIP Application

The Dell Hardware Instrumentation Package (HIP) server management application program generates alert messages that appear in the Simple Network Management Protocol (SNMP) trap log file. To see the trap log, select any enterprise under the SNMP trap log icon. (More information about the Alert Log window and options is provided in the Dell HIP online help and the HP OpenView Network Node Manager (NNM) Special Edition (SE) with Dell OpenManage HIP User's Guide.)

Alert log messages consist of information, status, warning, and failure messages for drive, temperature, fan, and power conditions. They can assist you with identifying a problem and may provide you with information to help you resolve the problem. Table 3 lists some of the alert log messages from the Dell HIP application.

Table 3. Dell HIP Application Alert Log Messages

Message	Cause	Corrective Action
Automatic management notification has occurred	The server stopped functioning and called the notification number specified in the DC Console Actions tab.

SCSI Hard-Disk Drive Indicator Codes

If a redundant arrays of independent disks (RAID) controller such as the optional PowerEdge RAID Controller (PERC) 2/Si controller is installed in the system, three light-emitting diode (LED) indicators on each of the hard-disk drive carriers provide information on the status of the SCSI hard-disk drives (see Figure 1). The SCSI backplane firmware controls the drive online and drive failure indicators.

Figure 1. Hard-Disk Drive Indicators

1	Drive online indicator
2	Drive activity indicator
3	Drive failure indicator

Table 4 lists the drive indicator patterns established by the SCSI backplane firmware. Different patterns are displayed as drive events occur in the system. For example, in the event of a hard-disk drive failure, 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.

NOTE: If you do not have a RAID controller installed, you will see only the "drive online" and "drive bay empty" indicator patterns.

Table 4. SCSI Hard-Disk Drive Indicator Patterns

Condition	Indicator Code
Identify drive	All three drive status indicators blink simultaneously.
Drive being prepared for removal	The three drive status indicators flash sequentially.
Drive ready for insertion or removal	All three drive status indicators are off.
Drive being prepared for operation	The drive online indicator is on. The drive activity light may flash briefly.
Drive bay empty	All three drive status indicators are off.
Drive predicted failure	The drive online indicator is on. The drive failure indicator blinks on briefly each second.
Drive failed	The drive online indicator turns off. The drive failure indicator blinks off briefly each second.
Drive rebuilding	The drive online indicator blinks rapidly.
Drive online	The drive online indicator is on.
