6.1.1 | About Subsystem Maintenance |
| Constant monitoring and maintenance of your RAID subsystem minimizes subsystem down- |
| time and preserves the working integrity of the system for a longer period of time. If any of the |
| subsystem components fail, they must be replaced as soon as possible. |
CAUTION!
Do not remove a failed component from the subsystem until you have a replacement on hand. If you remove a failed component without replacing it, the internal airflow will be disrupted and the system will overheat, causing damage to the subsystem.
All of the following components can be replaced in case of failure:
1.Controller modules – Section 6.2 Replacing Controller Module Components
2.Memory module – Section 6.3 DIMM Module Replacement
3.BBU – Section 6.4 Replacing a Faulty BBU Module
4.PSU modules – Section 6.5 Replacing a Faulty PSU Module
5.Cooling modules – Section 6.6 Cooling Module Maintenance
6.Hard drives – Section 6.7 Replacing a Failed Hard Drive

With the exception of the RAID controller module, all of the components on the RAID sub- system, including the PSU modules, cooling modules, and drive trays, are
Qualified technicians who are familiar with the RAID subsystem should be the only ones who make component replacements. If you are not familiar with the RAID subsystem or with RAID subsystem maintenance in general, it is strongly advised that you refer RAID subsystem maintenance to a suitably qualified maintenance technician.
Normalized airflow depends upon the presence of all subsystem components. A subsys- tem 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 compo- nents without a replacement can lead to permanent subsystem damage.
When replacing any
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.
