PAC Management Software: PAC Management Software is another browser-based GUI
(graphical user interface) software that you can install into a local or remote computer and
access via the network. The managing system communicates with the array via connection of
the existing host links or the Ethernet link to the
array’s Ethernet port.
1.5.2 Audible Alarms
The system comes with audible alarms that are triggered when certain active components fail or
when specific controller or system thresholds exceed. Whenever you hear an audible alarm, you must
determine the cause and solve the problem immediately.
Event notification messages indicate the completion or status of array configuration tasks and are
always accompanied by two or three successive and prolonged beeps. You can turn off the alarm using
the mute button on the front panel.
WARNING! Failure to respond when an audible alarm is set off can lead to permanent damage to the
system. When you hear an audible alarm, solve the problem immediately.
1.6 Hot-Swappable Components
The system has a number of hot-swappable parts that you can change while the system is still online
without affecting its operational integrity.
These hot-swappable components are user-maintained:
•
Controller module
•
PSU/cooling module
•
Hard disk drive
IMPORTANT! Only remove these hot-swappable components when replacement is needed.
NOTE: A normal airflow ensures sufficient cooling of the system and this can only be attained when
all components are properly installed. Remember to only remove the failed component if there is a
replacement on hand. For more information on replacing hot-swappable components, see chapter
System Maintenance .
