PAC Management Software:
The PAC Management Software is another browser-based GUI (Graphic 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.
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.
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:
•
PSU/Cooling Module
•
Hard Disk Drive(s)
•
Controller Module(s)
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 already a replacement. For more information on replacing hot-swappable components,
see chapter
System Maintenance
