MonShutdownNotification is sent if the environmental
monitor detects a testpoint reaching a critical state
and is about to initiate a shutdown.  This notification 
contains no objects so that it may be encoded and sent in the
shortest amount of time possible.  Even so, management
applications should not rely on receiving such a notification
as it may not be sent before the shutdown completes.

MonVoltageNotification is sent if the voltage 
measured at a given testpoint is outside the normal range 
for the testpoint (i.e. is at the warning, critical, or
shutdown stage).  Since such a notification is usually 
generated before the shutdown state is reached, it can 
convey more data and has a better chance of being sent 
than does the ciscoEnvMonShutdownNotification.
This notification is deprecated in favour of
ciscoEnvMonVoltStatusChangeNotif.

MonTemperatureNotification is sent if the 
temperature measured at a given testpoint is outside 
the normal range for the testpoint (i.e. is at the warning, 
critical, or shutdown stage).  Since such a Notification 
is usually generated before the shutdown state is reached,
it can convey more data and has a better chance of being
sent than does the ciscoEnvMonShutdownNotification.
This notification is deprecated in favour of 
ciscoEnvMonTempStatusChangeNotif.

MonFanNotification is sent if any one of
the fans in the fan array (where extant) fails. 
Since such a notification is usually generated before 
the shutdown state is reached, it can convey more 
data and has a better chance of being sent
than does the ciscoEnvMonShutdownNotification.
This notification is deprecated in favour of
ciscoEnvMonFanStatusChangeNotif.

MonRedundantSupplyNotification is sent if
the redundant power supply (where extant) fails. 
Since such a notification is usually generated before 
the shutdown state is reached, it can convey more 
data and has a better chance of being sent
than does the ciscoEnvMonShutdownNotification.
This notification is deprecated in favour of 
ciscoEnvMonSuppStatusChangeNotif.

MonVoltStatusChangeNotif is sent if there is 
change in the state of a device being monitored
by ciscoEnvMonVoltageState.

MonTempStatusChangeNotif is sent if there 
is change in the state of a device being monitored
by ciscoEnvMonTemperatureState.

MonFanStatusChangeNotif is sent if there 
is change in the state of a device being monitored
by ciscoEnvMonFanState.

MonSupplyStatChangeNotif is sent if there 
is change in the state of a device being monitored
by ciscoEnvMonSupplyState.
