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 SystemsInstallation and Troubleshooting Guide. Several different types dimm 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.

Memory of the same size/speed should go in slots that match in color. The colors represent the memory channels, and usually you would want to put matching RAM into matching DIMM slots. 0 LVL 91 Overall: Level 91 Components 39 Desktops_PCs 27 PCs 26 Message Active today Accepted Solution by:nobus2014-06-14 >> I recently purchased 2 sticks of 8GB << are you sure they are compatible ? the manual says :

Power Supply Features System Messages System Beep Codes Warning Messages Diagnostics Messages Alert Log Messages From the Dell OpenManage Server Agent Applications, operating systems, and the system itself are capable of identifying problems and alerting you to them. When a problem occurs, a message may appear on the monitor screen or a beep code may sound. 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 The system indicators and the front and back panel features are illustrated in Figures 2-1 through 2-5. This section also describes each type of message and lists the possible causes and actions you can take to resolve any problems indicated by a message. To determine what type of message you have received, read the following sections. Bezel Indicators When the bezel is in place on the system, it has two indicators (see Figure2-1). The hard-disk drive activity indicator and the ESM indicator. The ESM indicator flashes amber when the system needs attention. The ESM indicator indicates a power problem, a fan/temperature problem, a hard drive problem, or that the PCI expansion cards need attention. Figure 2-1. Bezel Indicators Front-Panel Indicators and Features Two indicators are located on the front-panel: the hard-disk drive indicator and the ESM indicator. The ESM indicator flashes amber when the system needs attention. The amber ESM indicator indicates a power problem, a system fan or power supply fan problem, temperature problem, a hard-disk drive problem, or that the PCI expansion cards need attention. The power supplies and hard-disk drives also have indicators which can be seen when the bezel is removed. The CD-ROM and diskette drives have green activity indicators. Figure 2-2.
