EonStor A08U/A12U-G2421 Installation and Hardware Reference Manual
terminal emulation program running on a management computer that is connected to
the subsystem’s serial port.
RAIDWatch: RAIDWatch is a premier web-based graphical user interface (GUI) that
can be installed on a remote computer and is used to access the array through LAN or
the Internet. The manager communicates with the array via the connection of the
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.
WARNING!
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 EonStor A12U-G2421 and A08U-G2421 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:
• Power supply units (PSUs)
• Cooling fan modules
• Hard drives
• BBU module
