When a continuous tone sounds, there are multiple alarm patterns sounding at the
same time (see example number 1 illustrated below).
Figure 20:
Alarm sound patterns
Other alarm patterns include three short buzzes followed by a longer silence, then
repeated (example number 2 above). This can indicate a serious problem that
requires immediate action such as high enclosure temperature or the system fan is
not installed. If you hear this, check the System Status and Fan LEDs. If these are
normal, it might indicate a physical drive problem, or a power supply problem. Check
the event log for more information.
Pattern number 3 above might indicate an LD offline. Pattern number 4 might be an
LD critical or bad sector on a physical disk.
