Subsystem Maintenance and Upgrading
5.1 Overview
5.1.1Maintenance
Constant monitoring and maintenance of your SS16i subsystem will minimize subsystem downtime and preserve 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.
WARNING!
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 module – Section 0
2.Memory module – Section 0
3.BBU module - Section 0
4.PSU modules – Section 5.5
5.Cooling fan modules (bundled with PSU modules, not separately available) – Section 0
6.Hard drives – Section 5.7
5.1.2General Notes on Component Replacement
With the exception of the RAID controller module, all of the components on the SS16i subsystem, including the PSU modules (along with the cooling modules within), and drive trays, are
Qualified engineers who are familiar with the SS16i 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 on 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.
