Dealing with hardware faults
Ensure that you have obtained a replacement module of the same type before
removing any faulty module.
v If the subsystem power is turned on and you remove any module, replace it
immediately. If the subsystem is used with modules or module blanks missing
for more than a few minutes, the enclosure can overheat, causing power failure
and data loss. Such use will invalidate the warranty.
v Replace a faulty drive with a drive of the same type and equal or greater
capacity.
v Refer to your vendor-supplied documentation when using storage software for
handling drive-related hardware faults.
v All drive bays must be installed with a drive carrier module in order to
maintain a balanced airflow.
v All the supplied plug-in power supply units, electronics modules and blank
modules must be in place for the air to flow correctly around the cabinet.
CAUTION:
Observe all conventional ESD precautions when handling modules and
components. Avoid contact with backplane components and module connectors,
etc.
Note: The top cover of the enclosure covers a service area which should be
accessed only by qualified service personnel. When the cover is replaced it
must be secured by turning the lock mechanism to the locked position.
Continuous operation during replacement
Depending on how the enclosure system is set up, if a disk unit fails, it can
normally be replaced without interrupting the use of the system.
