When inserting a removable module, take heed that 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.

5.2. Replacing Controller Module Components

5.2.1 Overview

The controller module in the AR3016G consists of the following replaceable
components:
•
•
If any of these components fails, it needs to be replaced. To replace any of
these components, the controller module must be removed.

in general, it is strongly advised that you refer AR3016G
maintenance to a suitably qualified maintenance engineer.
Normalized airflow depends upon the presence of all subsystem
components. A subsystem component, even if it has 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.
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
is very sensitive component and can be easily damaged.
