EonStor S12S-R/G1032 Installation and Hardware Reference Manual

General Notes on Component Replacement
Almost all of the major components on the S12S series, cooling
modules, PSUs, and drive trays, are hot-swappable and can be
replaced online.
Qualified engineers who are familiar with RAID storage hardware
should be the only ones who make component replacements. If
you are not familiar with the EonStor series or with RAID
subsystem maintenance in general, it is strongly advised that you
refer subsystem maintenance to a 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 lead to
permanent damage.
When replacing any 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.
When removing a component from the subsystem, ensure that all
previously stipulated precautions (see
Section 2.3
) are strictly
adhered to.
WARNING!
When inserting a removable module, take heed that
DO NOT USE
EXCESSIVE FORCE
! Forcing or slamming a module can damage the
connector pins either on the module itself or on the backplane. Gently
push the module until it reaches the end of module slot. Feel the
contact resistance and use slightly more force to ensure the module
connectors are properly mated. If the module comes with ejection
levers or retention screws, use them to secure the module.
