Dell PowerEdge 650 - Manual (Page 26)

System Beep Codes
When an error that cannot be reported on the monitor occurs during a boot routine, the system may emit a series of beeps that identify the problem.
When a beep code is emitted, record it on a copy of the Diagnostics Checklist in " Getting Help ," 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 a more serious cause. If you are still unable to resolve the
problem, see "
Getting Help ."

Faulty diskette, diskette/CD-drive
assembly, hard drive, or hard-drive
subsystem.
Replace the diskette. Replace the diskette/CD-drive subsystem. See " Removing the CD
and Diskette Drives " in "Installing Drives." If the problem persists, replace the faulty hard
drive. See " Hard Drives " in "Installing Drives."
NOTE: If the system boots without a keyboard, mouse, or monitor attached, the system will not issue beep codes related to those peripherals.
