Subsystem Maintenance

 

Constant monitoring and maintenance of your SATA-based subsystems 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.

6.1

Overview

 

 

 

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 Replacing or Upgrading Memory Modules

3.BBU module – Section 6.4 Replacing a Faulty BBU
4.PSU modules – Section 6.5 Replacing a Failed PSU Module

5.Cooling fan modules – Section 6.6 Replacing a Failed Cooling Fan Module

6.Hard drives – Section 6.7.2 Replacing a Failed Hard Drive

General Notes on Component Replacement

With the exception of the RAID controller module, all the components on the subsystems, including the PSU modules, cooling fan modules, BBU, and drive trays are hot-swappable and can be changed while the subsystem is still in operation.

Qualified technicians who are familiar with the subsystem should be the only ones who make component replacements. If you are not familiar with the subsystems and not famil- iar with RAID subsystem maintenance in general, it is strongly advised that you refer sub- system maintenance to a suitably qualified maintenance technician.

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 subsys- tem until a replacement is readily at hand and can be quickly installed. Removing a subsystem component without a replacement 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. Rough or improper handling of components can lead to irreparable damage.

When removing a 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 contains very sensitive components 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 extraction levers or retention screws, use them to secure the module.

Insert the new PSU module into the subsystem Once the previously removed cooling module has been installed, insert the new PSU module into the subsystem. Make sure the extraction lever is in its downright position so that the saddle notches on the lower edges of the handle can lock on to the edge metal brackets along the chassis inner walls.
