Indicators, Messages, and Codes
Dell™ PowerEdge™ 2500 Systems Installation and Troubleshooting Guide
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
). 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.
