Configuration Client functionality are given in the RAIDWatch User’s 

Manual.    

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

active components. 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 Section 3.2) 

•  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 jeopardize 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 Section 3.3) 

•  Inter-Integrated Circuit (I

C): The I

2

C bus monitors the operational 

integrity of the cooling modules, sensors for RAID controller 

board/backplane temperature and voltage readings. 

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 appropriate 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.
