The 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.

The following elements are interfaced to the RAID controller over a non-user-serviceable I

C 

bus:

•

PSU modules

•

Cooling modules

•

Temperature sensors (for the temperature of the backplane board and controller board)

The following active components come with LEDs to indicate the status of the individual com-

ponent:

•

RAID controller (5 LEDs)

•

LCD panel (3 LEDs)

•

BBU (2 LEDs)

•

Cooling modules (2 LEDs)

•

PSU modules (1 LED)

•

Drive trays (2 LEDs)

Firmware: The firmware is pre-installed software used to configure the subsystem. The latest 

firmware functionalities include Task Scheduler, Intelligent Drive Handling, and Media Scan. 

Media Scan handles low quality drives in both the degraded mode and during the rebuild pro-

cess. Maintenance tasks will then be performed on an entire array or specific hard drives. Var-

ious options are user-configurable such as priority, start time, and execution internals. 

Bosch RAIDWatch: Bosch 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 communi-

cates with the array via the connection of the existing host interface or Ethernet link to the 

array’s LAN port. 

The RAID subsystem comes with audible alarms that are triggered when certain active compo-

nents fail or when certain (controller or subsystem) thresholds are exceeded. Whenever you 

hear an audible alarm from the RAID 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.

Failing to respond when an audible alarm is heard can lead to permanent damage of the RAID 

subsystem. When an audible alarm is heard, rectify the problem as soon as possible.
