Crocus CNV Alarm attributes
Reference manual 125
9.2.1 Configuration alarm attributes
The following four configuration alarm attributes are already explained in Chapter 6 - Configuration
attributes, but are explained more thoroughly below.
crocusIfConv<2m/Nx64><Tt/Cv>/…/alarmMask
The alarmMask attribute enables or disables for each alarm of the corresponding object, whether it is
communicated to the central management system (e.g. HP OpenView
®
) or not.
Alarms are always seen in the alarmInfo of an object, regardless of the masking of the alarm. I.e. even if an
alarm is set to disabled in the alarmMask of an object, if the alarm condition is fulfilled then the alarm will be
set to on in the alarmInfo of that object. Also the alarm count and time in the performance information will
increment.
However, because this alarm is disabled:
• it will not be sent to the central management system (e.g. HP OpenView
®
)
• it will not cause a change of colour in the subsystem picture (refer to Chapter 10 - TMA subsystem
picture of the Crocus CNV)
• the bit string currentAlarms will not be shifted towards the value previousAlarms of the alarmInfo attribute
(refer to Section 9.2.2 General alarm attributes)
crocusIfConv<2m/Nx64><Tt/Cv>/…/alarmLevel
With this attribute, a priority level can be assigned to each alarm of the corresponding object. The alarm
level ranges from 0 to 254, where 0 is the lowest and 254 is the highest priority level.
The alarmLevel of an unmasked, active alarm is sent to the totalAlarmLevel of the top object
crocusIfConv<2m/Nx64><Tt/Cv>.
crocusIfConv<2m/Nx64>Cv/…/alarmContactHighMask
This attribute is present on the CV only.
The alarmContactHighMask attribute enables or disables for each alarm of the corresponding object,
whether:
• a visual indication is generated (blinking error LED)
• the alarm contacts on the CN4 card nest are driven
• an alarm is sent to the remote Crocus CNV (only on the Crocus Nx64 CNV in framed mode).
crocusIfConv<2m/Nx64>Cv/…/alarmContactLowMask
This attribute is present on the CV only.
The alarmContactLowMask attribute enables or disables for each alarm of the corresponding object, whether:
• a visual indication is generated (blinking error LED)
• the alarm contacts on the CN4 card nest are driven
an alarm is sent to the remote Crocus CNV (only on the Crocus Nx64 CNV in framed mode).
crocusIfConv<2m/Nx64>Tt/…/remoteAlarmMask
This attribute is present on the TT only.
The remoteAlarmMask attribute enables or disables for each alarm of the corresponding object, whether:
• a visual indication is generated (blinking error LED).
• an alarm is sent to the remote Crocus CNV.
By default, all the alarms in the remoteAlarmMask are set to disabled.
