Internet. The manager communicates with the array via the connection of the existing host
interface or Ethernet link to the RJ-45 LAN port.
2.4.4
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 pro-
longed beeps.
CAUTION!
Failing to respond when a critical alarm is heard can lead to permanent damage of the sub-
system. When an audible alarm is heard, rectify the problem as soon as possible.

Hot-Swappable Components
2.5.1
Hot-Swap Capabilities
The subsystem comes 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 opera-
tional integrity of the subsystem. These components should only be removed from the sub-
system when they are being replaced. At no other time should these components be removed
from the subsystem.
2.5.2
Components
The following components are all hot-swappable:
•
•
•
•
2.5.3
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-swapped when a replacement is
available. If a failed component is removed but not replaced, permanent damage to the sub-
system can result.
