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.

Controller module – Section 6.2 Replacing Controller Module Components

 

2.

Memory module – Section 6.3 DIMM Module Replacement

 

3.

BBU module - Section 6.4 Replacing a Faulty BBU Module

 

4.

PSU modules – Section 6.5 Replacing a Failed PSU Module

 

5.

Cooling fan modules – Section 6.6 Cooling Module Maintenance

 

6.

Hard drives – Section 6.7 Replacing a Failed Hard Drive

6.1.2

General Notes on Component Replacement

 

•

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.

 

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.
