Subsystem Maintenance and Upgrading

6.1

Overview

6.1.1

Maintenance

Constant monitoring and maintenance of your RAID subsystem will minimize subsystem down-
time 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.
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.
2.
3.
4.
5.
6.

General Notes on Component Replacement

•

•
When, if necessary, removing a RAID 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 is very sensitive and can be easily damaged.
CAUTION!
When inserting a removable module, DO NOT USE EXCESSIVE FORCE! Forcing or slamming a
module can damage the pins on the module connectors either on the module itself or on the
backplane. Gently push the module until it reaches the end of module slot. Feel the contact
resistance and use slightly more force to ensure the module connectors are correctly mated. If
the module comes with reject levers or retention screws, use them to secure the module.

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 hot-swappable
and can be replaced while the subsystem is still in operation
Qualified techniciens 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 and/
or with RAID subsystem maintenance in general, it is strongly advised that you refer sub-
system maintenance to a suitably qualified maintenance technicien.
Normalized airflow is directly dependent upon the presence of all subsystem compo-
nents. Even if a subsystem component fails, it should not be removed from the sub-
system 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 hot-swappable component, caution should be taken to ensure that
the components are handled in an appropriate manner. The rough or improper handling
of components can lead to irreparable damage.
