Installation and Troubleshooting Guide

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."

Replace the diskette. Ensure that the diskette drive, optical drive, and
hard- drive cables are properly connected. See "Troubleshooting a
Diskette Drive," "Troubleshooting an Optical Drive," or "Troubleshooting
SCSI Hard Drives" in "Troubleshooting Your System" for the appropriate
drive(s) installed in your system.
NOTE: If the system boots without a keyboard, mouse, or monitor attached, the system does not issue beep codes related to those peripherals.
CAUTION: Many repairs may only be done by a certified service technician. You should only perform troubleshooting and simple repairs as
authorized in your product documentation, or as directed by the online or telephone service and support team. Damage due to servicing that is not
authorized by Dell is not covered by your warranty. Read and follow the safety instructions that came with the product.
