EonStor F16F-R/S4031 Installation and Hardware Reference Manual
The graphics used in the following sections are only showing the F16F-
R4031 6-channel subsystem. You may follow the same maintenance
procedures to work on an F16F-S4031 subsystem.

General Notes on Component Replacement

Almost all of the major components on the F16F-R/S4031,
including the redundant controller modules in F16F-R4031,
PSUs, cooling modules, I/O modules, and disk drives are hot-
swappable and can be replaced online.
Qualified engineers who are familiar with the F16F subsystems
and RAID storage technologies should be the only ones who
make component replacements. If you are not familiar with the
F16F series or with RAID subsystem maintenance in general, it
is strongly advised that you refer system maintenance to a
suitably qualified engineer.
Normalized airflow depends upon the presence of all subsystem
components. A subsystem component, even if it has failed,
should not be removed from the subsystem until a replacement is
readily at hand and can be quickly installed. Removing
subsystem components without a replacement can cause the
system to quickly overheat.
When replacing a hot-swappable component, caution should be
taken to ensure that the components are handled in an
appropriate manner. Rough or improper handling of components
can lead to irreparable damage.
If the single controller module in F16F-S4031 fails, it is necessary
to power down the subsystem and replace the controller. If a
controller in a dual-controller F16F-R4031 fails, the controller can
be replaced online.
When removing a component from the subsystem, ensure that
the all previously stipulated precautions (see Section 2.3) are
strictly followed and adhered to.
