2.4 Subsystem Monitoring
The SATA-based RAID subsystem comes with a number of different monitoring methods that
provide you with continual updates on the status of the system and individual components.
The following monitoring features are included in the subsystem.
2.4.1 I
2
C Bus
The following subsystem elements are interfaced to the RAID controller over a non-user-ser-
viceable I
2
C bus:
• Cooling fan modules
• PSUs
• Temperature sensors
2.4.2 LED Indicators
The following active components come with LEDs to indicate the status of the individual com-
ponents:
• RAID controller
• LCD panel
• Cooling fan module
• PSU module
• BBU module
• Drive trays
2.4.3 Firmware and Bosch RAIDWatch GUI
Firmware: The firmware is pre-installed software that is used to configure the subsystem. The
firmware can be accessed either through the LCD keypad panel or a terminal emulation pro-
gram running on a management computer that is connected to the subsystem’s serial port.
Bosch RAIDWatch: Bosch 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.
2.4.4 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. 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 pro-
longed beeps.
CAUTION!
Failing to respond when a critical alarm is heard can lead to permanent damage of the subsys-
tem. When an audible alarm is heard, rectify the problem as soon as possible.
