1.3.3
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 front LCD 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, web-based graphics user interface
(GUI) that can be installed on a remote computer and accessed via the web.
The manager communicates with the array via the connection of the existing
host interface or Ethernet link to the array’s LAN port.
1.3.4 Audible
Alarms
The A16F-R2422 subsystem comes 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 the
A16F-R2422, 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.
WARNING:
Failing to respond when an audible alarm is heard can lead to permanent
damage of the A16F-R2422. 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 A16F-R2422 subsystem comes with a number of hot-swappable
components that can be exchanged while the subsystem is still online
