Dell PowerEdge 6850 - Manual (Page 31)

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 -9 . 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. See " Running the System Diagnostics " for more information. If you are still unable to
resolve the problem, see " Getting Help ."
