System Monitoring Features
There are a number of monitoring approaches that provide the operating status of
individual components.
1.4.1
Monitoring
The system can monitor the following:
PSU
Cooling module
Cooling Module Speed Adjustment:
If temperature reading(s) exceed the temperature threshold, the
firmware automatically raises the rotation speed of all cooling fans.
Enclosure thermal sensor
Hard drive
1.4.2
I
2
C bus
The presence detection circuitry and temperature sensors are interfaced through a
non-user-serviceable I
2
C bus. When JBODs are attached to the NAS system, JBOD
component statuses are reported through the in-band methodology over the
expansion links that is managed by a proprietary enclosure service.
1.4.3
Audible Alarms
The system comes with audible alarms that are triggered when certain active
components fail or when certain controller or system thresholds are exceeded.
Whenever you hear an audible alarm, it is imperative that you determine the cause
and rectify the problem immediately.
Event notification messages indicate the completion or status of array configuration
tasks and are always accompanied by two or three successive and prolonged beeps.
When sounded, please use the mute button on the
front status panel
to turn it off.
WARNING
Failing to respond when an audible alarm is heard can lead to permanent damage to
the system. When an audible alarm is heard, rectify the problem as soon as possible.
