Codes and Error Messages
Dell™ PowerEdge™ 500SC Systems Service Manual
Overview
This section describes beep codes and system error messages that can occur during system start-up or, in the case of some failures, during normal system
operation. The tables in this section list faults that can cause a beep code or system error message to occur and the probable causes of the fault in each case.
This section also suggests actions you can take to resolve problems indicated by a 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 system
diagnostics to help isolate the source of the problem. See "
Running the System Diagnostics
."
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 log messages
l
Front-panel indicators
System Messages
System messages alert you to a possible operating system problem or to a conflict between the software and hardware.
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 system diagnostics (see the Installation and Troubleshooting Guide) to
assist in troubleshooting the problem.
