5.2. Overview
5.2.1 About Subsystem Maintenance
Constant monitoring and maintenance of your ES U16U subsystem will minimize the
chance of system downtime and preserve the working integrity of the system for a longer
period of time. If any of the subsystem plug-in modules fails, 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 the following components can be replaced in case of failure:
1.
Controller Modules
2.
PSU Modules
3.
Cooling Fan Modules
4.
Hard Drives
5.
Hard Drive trays
5.2.2 General Notes on Component Replacement
♦
With the exception of the RAID controller module, all the components on the ES
subsystem, including the PSU modules, cooling FAN modules, and drive trays are
hot-swappable and can be changed while the subsystem is still in operation.
♦
Qualified engineers who are familiar with the ES subsystem should be the only
ones who make component replacements. If a user is not familiar with the ES
subsystem and not familiar with RAID subsystem maintenance in general, it is
strongly advised that they refer ES subsystem maintenance to a suitably qualified
maintenance engineer.
♦
Normalized airflow is directly dependent upon the presence of all subsystem
components. A subsystem component, even if 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.
