Alert Messages
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 or front-panel status LCD, or a beep code may sound.
A variety of messages and codes can indicate when the system is not functioning properly:
l System-status indicators
l System identification identifiers
l Front-panel indicators and features
l Back-panel indicators and features
l Power indicator codes
l SCSI hard-drive indicator codes
l NIC indicator codes
l Cooling fan indicator codes
l LCD status messages
l System messages
l System beep codes
l Warning messages
l Diagnostics messages
l Alert messages
The system indicators and features are illustrated in Figure2-1 through Figure2-6. 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
subsections.
System-Status Indicators
The system's bezel has an indictor that can represent system status when the bezel is installed (see Figure2-1). The indicator signifies when the system is
operating properly or when the system needs attention. The back-panel indicator functions the same as the bezel indicator. The back-panel indicator
connector allows an indicator to be attached that will also function the same as the bezel indicator (see Figure2-3).
A caution code signifies a problem with microprocessors, power supply, system or power-supply fans, system temperature, hard drives, system memory,
expansion cards, or integrated SCSI controller.
Table2-1 lists the system's status indicator codes.
