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.
3.2 Status-indicating LEDs
3.2.1 Brief Overview of the LEDs
The A16F-R2422 has status-indicating LEDs distributed over the active
components that inform subsystem managers about each component
operational status. The list in Table 3-1 shows the number of LEDs assigned
to each component.

Configuration Client: The Configuration Client is a powerful
module that runs as an independent program from RAIDWatch
and can be installed on different hosts. It is used for event
notification via email, fax, LAN broadcast, SNMP traps, MSN
Messenger, ICQ, SMS (Short Message Service), and the
configuration utility screen. The Configuration Client helps
prevent blind time and keeps you constantly informed as to the
status of the storage management subsystem. Instructions on
activating the Configuration Client functionality are given in the
RAIDWatch User's Manual.
LEDs: Device-status-indicating LEDs are located on all A16F-
R2422 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 that are present 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 occurs. 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. If a subsystem
manager is present, the manager should use either the LCD panel
or the PC hyper-terminal to determine the cause of the alarm and
take the appropriate corrective measures. (See Section 3.3)

I
C: The I
C bus monitors the operational integrity of the PSUs,
cooling modules, voltage readings, and RAID controller board
temperature. (See Section 3.4)
