NOTE
If you are getting random errors in your data files, they may be getting
corrupted by voltage spikes on your power line. If you are experiencing any
of the above symptoms that might indicate voltage spikes on the power line,
you may want to install a surge suppressor between the power outlet and the
server power cord.
If the problem recurs after you have checked and corrected all the above items, refer to "More
Troubleshooting Procedures" on page 264.
If you receive any error messages, refer to "Error Codes and Messages" on page 269 for an

More Troubleshooting Procedures
This section provides a more detailed approach to identifying a problem and locating its source.
Preparing the Server for Diagnostic Testing
CAUTION
Before disconnecting any peripheral cables from the server, turn off the
server and any external peripheral devices. Failure to do so can cause
permanent damage to the server and/or the peripheral devices.
1. Turn off the server and all external peripheral devices. Disconnect all devices from the server,
except the keyboard and video monitor.
2. Make sure the server power cord is plugged into a properly grounded AC outlet. (Chapter 2)
3. Make sure your video monitor and keyboard are correctly connected to the server. Turn on the
monitor. Set its brightness and contrast controls to at least two-thirds of their maximum
ranges (refer to the documentation supplied with your monitor).
4. If the operating system normally loads from the hard disk drive, make sure there is no diskette
in drive A. If the OS normally loads from a diskette, place the diskette containing the OS files
in drive A.
5. Turn on the server. If the power LED does not light, refer to "Power Light Does Not Light" on
page 266.
