Audible Alarms
The enclosure comes with audible alarms that are triggered when
certain active components fail or when certain subsystem thresholds
are exceeded. Whenever you hear an audible alarm from the
enclosure, it is imperative that you determine the cause and rectify
the problem immediately.
Event notification messages indicate the completion or status of
array configuration tasks and are always accompanied by two (2) or
three (3) successive and prolonged beeps.
Failing to respond when an audible alarm is heard can lead to
permanent damage of the enclosure components. When an audible
alarm is heard, rectify the problem as soon as possible.

Hot-swappable Components
Proper subsystem cooling is referred to as "normalized" airflow.
Normalized airflow ensures the sufficient cooling of the subsystem
and is only attained when all components are properly installed.
Therefore, a failed component should only be swapped when a
replacement is available. If a failed component is removed but not
replaced, airflow will be disrupted and system can rapidly
accumulate heat and cause damage to its components.
1.5.1
Hot-swap Capability
The enclosure comes with a number of hot-swappable components
that can be exchanged while the subsystem is still online without
affecting the operational integrity of the subsystem. These
components should only be removed from the subsystem when they
are being replaced. At no other time should these components be
removed from the subsystem.
1.5.2
Components
The following components are hot-swappable:
Hot-swappable Components
RAID controllers, each module has six (6) LEDs and one (1)
LED specifically for the Restore Default Functionality
Cooling modules (2 LEDs on PSU canister for each module)
PSUs (1 LED on each module)
