Enclosure Alarms - Dell PowerVault MD1120 Hardware Owner's Manual

Enclosure Alarms

An audible alarm is activated if any of the fault conditions listed in Table 1-6
occur. If a critical event occurs, the alarm sounds continuously. If a noncritical
event occurs, the alarm sounds every 10 seconds.
NOTE:
The audible alarm is disabled by default. To enable the alarm, you must
change the default setting in server administrator. For more information, see server
administrator storage management service documentation.
Table 1-6. Critical and Noncritical Events
Critical Events
Two or more fan blowers have failed or
a power supply/cooling fan module is
not installed.
One or more temperature sensors are
in critical range.
NOTE:
It is rare for both EMMs to fail simultaneously. However, if this occurs, the
enclosure cannot issue critical or noncritical event alarms for any enclosure
component.
