existing host interface or Ethernet link to the RJ-45 LAN port.
1.3.4 Audible Alarms
The subsystems come with audible alarms that are triggered when certain active
components fail or when certain (controller or subsystem) thresholds are exceeded. If
you hear hastily repeated beep tones from the subsystems it is imperative that you
immediately determine and rectify the problem.
Event notification messages indicate the completion of or the condition when
proceeding with array configuration tasks and are always accompanied by two or
three successive and prolonged beeps.
Failing to respond when a critical alarm is heard can lead to permanent damage of
the subsystem. When an audible alarm is heard, rectify the problem as soon as
possible.
1.4 Hot-Swappable Components
1.4.1 Hot-Swap Capabilities
The Galaxy RAID 12 and 8 Bay subsystems come with a number of hot-swappable
components. A hot-swap component is one 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.
1.4.2 Components
The following components are all hot-swappable:
•
•
•
•
1.4.3 Normalized Airflow
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 hot-
