Subsystem Monitoring; I 2 C Bus; Led Indicators - Infortrend EonStor S12F-R1432 Installation And Hardware Reference Manual

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 that the subsystem
has not discovered any erroneous conditions.

Subsystem Monitoring

The S12F subsystem comes with a number of different monitoring
approaches that provide you with continual updates on the status of
the subsystem and individual components.

1.4.1 I C bus
The presence detection circuitry and temperature sensors are
interfaced through a non-user-serviceable I
monitor the presence of PSU modules, cooling modules, and the
internal temperature of the subsystem. If any problem is detected, it
will be reported in various ways, such as through the embedded
firmware utility or SANWatch Enclosure View. When JBODs are
attached, JBOD component statuses are reported through the in-
band methodology over the expansion links that is managed by a
proprietary enclosure service.
