Falcon 24 Bay SCSI-SATA Installation and Hardware Reference Manual
5.1.2 General Notes on Component Replacement
With the exception of the RAID controller module on the Falcon model, all of
the components on the subsystem, 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 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 upon 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 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 and can be easily damaged.
WARNING!
When inserting a removable module, DONOT USE EXCESSIVE FORCE! Forcing
or slamming a module can damage the connector pins on the module or the backplane.
Gently push the module in until it reaches the end of module slot. Once you feel the
contact resistance, use slightly more pressure to ensure the module connectors are
correctly mated. Use the extraction levers or retention screws to secure the module.
