Falcon II SCSI-SATA Installation and Hardware Reference Manual
• Qualified engineers who are familiar with the FALCON II should be
the only ones who make component replacements. If you are not
familiar with the FALCON II or with RAID subsystem maintenance in
general, it is strongly advised that you refer FALCON II
maintenance to a suitably qualified maintenance 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 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 and the I/O
board on which it is mounted are very sensitive components and can be
easily damaged.
5.2 Replacing Controller Module Components
The controller module in the FALCON II consists of the following
replaceable components:
• DDR RAM DIMM module
• Controller module
If any of these components fail, it need to be replaced. To replace any of
these components, the system power must first be turned off, and the
controller module must be removed from the FALCON II.
5.2.1 Controller Module Maintenance Overview
• The controller module contains a DDR RAM DIMM module. When
replacing the controller module, the DIMM module must be removed
from the old controller module and reinstalled onto the new controller
module.
• When replacing the controller module, always remember that the
controller board is one of the most sensitive components in the
FALCON II. All previously stipulated safety precautions (see Section
2.3) must be strictly adhered to. Failure to adhere to these precautions
can result in permanent damage to the controller board, resulting in
lengthy delays for the end user.
