Troubleshooting is based on observation of server status indications and error messages, and by
checking system event logs. You can observe the LED indicators on the front and rear of the
server. Error messages are displayed on local and remote consoles. System history (console,
event, and history logs) is available through the iLO MP, and is accessed through the console.
Offline troubleshooting programs are available on the resource CD that is shipped with the
