2. Elevated temperature: if the temperature breaches the upper
threshold set for any of the interior temperature sensors, the
cooling fans automatically raise their rotation speed.
3. During the subsystem initialization stage, the cooling fans
operate at the high speed and return to low speed once the
initialization process is completed and no erroneous
condition is detected.
1.4 Enclosure
Monitoring
The enclosure comes with a number of different monitoring methods
that provide you with continual updates on the status of the system
and the individual components. The following monitoring features are
included in the subsystem.
1.4.1 I
2
C bus
The following subsystem elements are interfaced to the RAID
controller over a non-user-serviceable I
2
C bus:
PSUs
Cooling
modules
Temperature sensors (that reside on the controller board and
backplane board)
The operating statuses of the above modules are then reported via
the In-band method through the SAS link with a RAID subsystem.
1.4.2
Proprietary In-band Enclosure Service
The component statuses of the expansion enclosures are constantly
polled over the RAID-to-JBOD SAS links. You can see expansion
enclosure status via firmware configuration utility or Infortrend’s
management software.
1.4.3 LED
Indicators
The following components come with LEDs to indicate the status of
individual components. Please refer to
