System Beep Codes Dell™ PowerEdge™ 2400 Systems

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.

Table 2. System Beep Codes 
Code Cause Corrective Action
1-1-3 CMOS write/read failure Replace the system board.
1-1-4 BIOS checksum failure Reflash the BIOS firmware. If the problem persists, replace the system board.
1-2-1
1-2-2

1-2-3

Programmable interval-timer failureDMA initialization failure

DMA page register write/read failure

Replace the system board.
1-3-1 Main-memory refresh verification failure Remove and reseat the DIMMs. If the problem persists, replace one or more DIMMs. If the problem still persists, replace the system board.
1-3-2 No memory installed Remove and reseat the DIMMs. If the problem persists, replace the DIMMs. If the problem still persists, replace the system board.

Replace the system board.
3-2-4 Keyboard-controller test failure Check the keyboard cable and connector for proper connection. If the problem persists, run the keyboard test in the Dell Diagnostics to determine whether the keyboard or keyboard controller is faulty. If the keyboard controller is faulty, replace the system board.
3-3-1 CMOS failure Run the system board test in the Dell Diagnostics to isolate the problem. 
3-3-2 System configuration check failure Replace the system board.
3-3-3 Keyboard controller not detected Replace the system board.

Run the video tests in the Dell Diagnostics. 
4-2-14-2-2 No timer tickShutdown failure Replace the system board.
4-2-3 Gate A20 failure Replace the system board.
4-2-4 Unexpected interrupt in protected mode Ensure that all expansion cards are properly seated, and then reboot the system.
4-3-1 Improperly seated or faulty DIMMs Remove and reseat the DIMMs. If the problem persists, replace the DIMMs. If the problem still persists, replace the system board.
4-3-3 Defective system board Replace the system board.
4-3-4 Time-of-day clock stopped Replace the battery. If the problem persists, replace the system board.
4-4-1 Super I/O chip failure (defective system board) Replace the system board.
4-4-2 Parallel-port test failure (defective system board) Replace the system board.
4-4-3 Math coprocessor failure (defective microprocessor) Remove and reseat the specified microprocessor. If the problem still persists, replace the microprocessor.
4-4-4 Cache test failure (defective microprocessor) Remove and reseat the specified microprocessor. If the problem still persists, replace the microprocessor.

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
