Galaxy A16F-R2431 Installation and Hardware Reference Manual

Overview
5.1.2 General Notes on Component Replacement
Almost all of the major components on the A16F series, including the
RAID controllers in the controller pair of A16F-R2431, 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 Galaxy series or with RAID subsystem
maintenance in general, it is strongly advised that you refer subsystem
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 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.
If a controller module in the dual-controller configuration, A16F-
R2431, fails, the controller can be replaced online.
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 rejection levers or retention screws, use them
to secure the module.
