Dell PowerEdge 2850 - Manual (Page 22)

If a beep code is emitted, write down the series of beeps and then look it up in Table 2 -10 . 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 2-10. System Beep Codes
CAUTION: Only trained service technicians are authorized to remove the system cover and access any of the components inside the system. See
your Product Information Guide for complete information about safety precautions, working inside the computer, and protecting against
electrostatic discharge.
