System Beep Codes



If an error that cannot be reported on the screen occurs during POST, the system may emit a series of beeps that identifies the problem.



If a beep code is emitted, write down the series of beeps and then look it up in Table2-4. If you are unable to resolve the problem by looking up the meaning

of the beep code, use system diagnostics to identify the possible cause. If you are still unable to resolve the problem, see "Getting Help."



Table 2-4.ServerModuleBeepCodes

NOTE: If the system boots without a keyboard, mouse, or monitor attached, the system does not issue beep codes related to those peripherals.
