Indicators, Messages, and Codes
Dell™PowerEdge™2500SystemsInstallationandTroubleshootingGuide
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:
l System messages
l System beep codes
l Warning messages
l Diagnostics messages
l Alert messages
l 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.

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.
