EonStor A16E-G2130-4 Installation and Hardware Reference Manual
Qualified engineers who are familiar with the A16E-G2130-4 subsystem should be
the only ones who make component replacements. If you are not familiar with the
subsystem and/or with RAID subsystem maintenance in general, it is strongly
advised that you refer subsystem maintenance to a suitably qualified maintenance
engineer.
Normalized airflow is directly dependent on the presence of all subsystem
components. Even if a subsystem component fails, it should not be removed from the
subsystem until a replacement is readily at hand and can be quickly installed.
Removing a subsystem component without replacing it can lead to permanent
subsystem 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 RAID controller module from the subsystem, ensure that your
applications running on servers have been properly closed, users notified of the down
time, all cached writes conducted, et. Ensure that power has been turned off and that
all precautionary measures, without exception, are adhered to. The controller board is
very sensitive and can be easily damaged.
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 correctly mated. If the module comes with rejection levers or
retention screws, use them to secure the module.
