5.1.2 General Notes on Component Replacement
A RAID controller is replaced when powered down. Other component
modules, including the PSU modules (along with the cooling modules
within) and drive trays, are hot-swappable and can be replaced while the
system is operating.
Qualified engineers who are familiar with the system should be the only
ones who make component replacements. If you are not familiar with the
system and/or with RAID system maintenance in general, it is strongly
advised that you refer system maintenance to a suitably qualified
engineer.
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 from a single-controller system, ensure
that your applications have been properly closed, users notified of the
downtime, all cached writes conducted, etc. Ensure that all precautionary
measures, without exception, are adhered to.
WARNING!
When inserting a removable module,
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 ejection levers or retention screws, use them to secure the
module.
