Galaxy A16F-R2422 Installation and Hardware Reference Manual
5.1.2 General Notes on Component Replacement
•
With the exception of the RAID controller module, all of the
components on the A16F-R2422, including the PSU modules, cooling
modules, and drive trays, are hot-swappable and can be changed while
the subsystem is still in operation.
•
Qualified engineers who are familiar with the A16F-R2422 should be
the only ones who make component replacements. If you are not
familiar with the A16F-R2422 or with RAID subsystem maintenance in
general, it is strongly advised that you refer A16F-R2422 maintenance
to a suitably qualified maintenance 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 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 controller module from the subsystem, ensure that
the power has been turned off and that all precautionary measures,
without exception, are adhered to. The controller board is very sensitive
component and can be easily damaged.
When inserting a removable module, take heed that DO NOT USE
EXCESSIVE FORCE! Forcing or slamming a module can damage the
pins on the module connectors 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
extraction levers or retention screws, use them to secure the module.
