Monitoring the DuraStor Storage Subsystem
If the Fault LED and a Controller Status LED light up
simultaneously, there is a fault condition on that controller.
Audible Alarm
An audible alarm sounds when the Fault LED lights up, or when
the RAID appliance’s temperature or voltage enters warning or
shutdown range.
You can silence the alarm by touching any button on the OCP.
The temperature and voltage thresholds for each alarm are shown
in
Table 4-2

Check the ambient temperature
and lower it if needed.
(Ambient temperature should
be less than 45 °C.)
Onboard temperature:
■
Warning—0 °C to 5 °C and
45 °C to 50 °C
■
Shutdown—0 °C and 50 °C,
<0 °C, >50 °C

temperature.
VCC Voltage:
■
Warning—5 V -3.5% and +6.5%
■
Shutdown—5 V -6.5% and
+10%
Check your system monitor to
