*The buzzer sound indicates that a condition requiring immediate attention has
occurred.
The buzzer alarm is triggered by the following conditions:
1. Hard drive failure
2. Fan failure
3. System temperature over 45º Celsius.
Early versions of Supermicro SAS2 backplanes come equipped with a buzzer. New
versions of these backplanes no longer support a buzzer. We recommend using
the LSI MegaRAID Storage Manager or a similar management application to trigger
an email alert instead.
