Notes:
If you hear more than one beep, or no beep, check to

operating system as described in your
operating-system documentation. Also, see
Chapter 2, “Installing Your Software” on page 27. If
an error message appears, or if your screen is blank,
see Chapter 5, “Solving Problems” on page 213.
If your server stops running during testing or normal
operation, call for service. Describe the problem to
the service technician.
