Bosch Security Systems

This chapter provides information on how to monitor the subsystem.

The subsystem is equipped with a variety of self-monitoring features that help to keep subsys-

tem managers informed of the subsystem operational status. These monitoring features pro-

vide vital feedback to help you maintain the operational integrity of the subsystem. Prompt 

response to warnings and subsystem component failure notifications will ensure safe opera-

tion of the subsystem and help ensure the longevity of the subsystems.

Self-monitoring features include:

•

Firmware (FW): The RAID controllers in the subsystems come with pre-installed FW. The 

FW can be accessed using either the LCD keypad panel or a PC running terminal software 

through the RS-232C (audio jack) serial port. Device status information can be obtained 

from the FW. 

•

Bosch RAIDWatch: Bosch RAIDWatch is a fully integrated Java based Graphical User 

Interface (GUI) that came with the subsystem and can be used to monitor and maintain 

the subsystem using web browsers. Connection to a Bosch RAIDWatch station is made 

using the existing Ethernet ports.

•

The Bosch RAIDWatch Panel View can be customized to show a direct, graphical repre-

sentation of the subsystem in the content panel of the Bosch RAIDWatch screen. Panel 

View allows you to quickly determine the operational status of critical components. 

•

Configuration Client: The powerful Configuration Client sub-module can be used to keep 

you informed of system events via a variety of communication methods like email, LAN 

broadcast, fax, pager, MSN messenger, ICQ, and SMS. The sub-module runs as an inde-

pendent program from Bosch RAIDWatch main program. The Configuration Client helps 

prevent blind time and keeps you constantly informed as to the status of the storage 

management subsystem. 

•

LEDs: Device-status-indicating LEDs are placed on all of the subsystems’ active compo-

nents. These LEDs inform you of the integrity of a given component or a given link. You 

should become familiar with the different LEDs on the subsystem and be aware of their 

functions. (See Figure 4.2)

•

Audible Alarm: An audible alarm is present on the subsystem controller board and will be 

triggered if any of a number of threatening events occurred. These events usually jeopar-

dize the functional and operational integrity of the controller board and must be heeded 

at all times. Events such as a breaching of the temperature threshold will trigger the 

alarm and if an onsite subsystem manager is present, the manager should, using either 

the LCD panel or the PC hyper-terminal, determine the cause of the alarm and take the 

appropriate corrective measures. (See Figure 4.3)

•

Inter-Integrated Circuit (I

C): The I

C bus monitors the operational integrity of the cool-

ing modules, sensors for RAID controller board/backplane temperature and voltage read-

ings.

Subsystem monitoring is a necessary part of subsystem management. If failure events or other 

disruptive events are detected and reported, the subsystem managers must take the appropri-

ate action to rectify the problem. Failure to act in a properly specified manner to a system 

event (like overheating) can cause severe and permanent damage to the subsystem.
