8.2 Audio Diagnostics
If the workstation beeps continuously, the keyboard has a bad connection or there is
a stuck key on the keyboard. To resolve the problem:
■ Inspect for a stuck key on the keyboard and release the stuck key.
■ Disconnect and reconnect the keyboard.
■ Replace the keyboard.
8.3 Display Diagnostics
Error messages displayed on the monitor are generated from the Solaris OS or the
OpenBoot PROM. See the following sections:
■ See “Predictive Self-Healing Overview” on page 9-1.
■ See “OpenBoot PROM Messages” on page 12-11.
If you experience any other monitor problems, see the documentation for the
