Chapter 5: Subsystem Maintenance
5.1.2General Notes on Component Replacement
All of the components on the subsystem, including the RAID controllers, PSU modules, cooling modules, and drive trays, are
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
WARNING!
When inserting a removable module, DO NOT USE EXCESSIVE FORCE! Forcing or slamming a module into the chassis 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 properly mated. Use the extraction levers or retention screws to secure the module.
