IMPORTANT:
(1.) When the subsystem is online and a Power Supply fails,
and the replacement Power Supply module is not yet
available, don’t remove or disconnect the failed Power
Supply module. This is to maintain proper airflow within the
enclosure, since the fans will still be working.
(2.) When the subsystem (redundant controller mode) is
online and a component, such as RAID Controller module or
Expander module, fails and the replacement is not yet
available, in order to maintain proper airflow within the
enclosure, the failed module can be disconnected just about
an inch but not entirely removed from the slot. Another
option is to use a cover plate to temporarily cover the slot of
the removed module. This is needed to maintain proper
airflow within the enclosure.
(3.) When replacing a failed component online, it is not
recommended to remove the failed component for a long
period of time; proper air flow within the enclosure might
fail causing high controller / disk drive temperature.
