1.4.3 Firmware (FW) and RAIDWatch GUI
Firmware:
The firmware (FW) is pre-installed software used to configure
the subsystem. The FW can be accessed either through the LCD keypad
panel or a terminal emulation program running on a management computer
that is connected to the subsystem’s serial port.
RAIDWatch:
RAIDWatch is a premier, browser-based or Java-based
graphical user interface (GUI) that can be installed on a local/remote
computer and accessed via LAN/WAN. The manager communicates with
the array via the connection of the existing host interface or Ethernet link to
the array’s Ethernet port.
1.4.4 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. Whenever you hear an audible alarm from a subsystem, it is
imperative that you determine the cause and rectify the problem
immediately.
Event notification messages indicate the completion or status of array
configuration tasks and are always accompanied by two (2) or three (3)
successive and prolonged beeps.
CAUTION!
Failing to respond when an audible alarm is heard can lead to permanent
damage of the subsystem. When an audible alarm is heard, rectify the
problem as soon as possible.
