6Managing Alarms of the GGSN9811About This Chapter
This functionis used to detect the hardware or software fault during the running of the
GGSN9811. The information concerning the detected fault is displayed. The information is
transferred tothe alarm box through the convert management system. Then, the alarm box sends
the visual andaudible signals to inform the maintenance personnel of the fault.
6.1 Related Concepts
This part describes the concepts of the alarm type, alarm severity level, alarm time, and alarm
box concerning the alarm management.
6.2 BrowsingAlarmsThe Browse Alarmwindow displays the fault alarm and the event alarm reported in the system.
6.3 QueryingAlarm Logs
The system can display the information of the history alarm that meets the querying
requirements. Thus, you can know the historical running state of the device. After the command
to query the alarm log is issued, the real-time alarm can be automatically added in the query
alarm log window.
6.4 Saving Alarms
The alarm management of the local maintenance terminal (LMT) provides the functions of
saving all results and selected results.
6.5 Printing Alarm InformationThis part describes how to print the alarm information on the local maintenance terminal (LMT).
The alarm information can be saved as a file of which the suffix is .prnby selecting Print To
Filein the Printdialog box.
6.6 Processing An Alarm
This part describes how to process the single alarm and modify the alarm configuration
information that is pre-determined by the system.
6.7 Managing the Convert Management System
The convert management system runs on the computer where the local maintenance terminal
(LMT) is installed. The computer is connected to the alarm box through the serial port. The
convert management system can transfer the alarm commands and the alarm information
reported from the back administration module (BAM) to the alarm box. Thus, the alarm box can

6.1 Related Concepts
This part describes the concepts of the alarm type, alarm severity level, alarm time, and alarm
box concerning the alarm management.
6.1.1 Alarm Types
The alarms contain event alarms and fault alarms (active alarms and cleared alarms).
6.1.2 Alarm Severity Levels
The alarm severity level is used to identify how serious the alarm is. The alarm severity level
can be critical, major, minor, and warning.
6.1.3 Categories of Alarm Events
The event alarms can be triggered by the following: power system, environment system,
signaling system, trunk system, hardware system, software system, running system,
communication system, service quality, and processing error.
6.1.4 Alarm Box
The GGSN9811 uses the universal alarm box of Huawei Technologies Co., Ltd (hereinafter
referred to as Huawei).
6.1.1 Alarm Types
The alarms contain event alarms and fault alarms (active alarms and cleared alarms).
Fault Alarms and Event Alarms
l
Fault alarmsThe fault alarm is caused by hardware fault such as board fault. The fault alarm can be
cleared after the hardware fault is rectified. In this case, the system reports the cleared alarm
notifying that the fault is rectified. Each fault alarm corresponds to one cleared alarm. The
severity level of the fault alarm is higher than that of the event alarm.
l Event alarms
The event alarm is an occasional alarm during the running of the device. It indicates that
the system is abnormal at the moment, for example, path congestion. Some event alarms
are reported periodically. After the event alarm is cleared, the cleared alarm does not occur.
Active Alarms and Cleared Alarms
The active alarm and the cleared alarm are fault alarms.
l Cleared alarms
The fault alarm can be cleared after the hardware fault is rectified. In this case, the system
reports the cleared alarm notifying that the fault is rectified.
l Active alarms
The active alarm refers to the fault alarm that is not cleared.
6.1.2 Alarm Severity Levels
The alarm severity level is used to identify how serious the alarm is. The alarm severity levelcan be critical, major, minor, and warning.

Table 6-1lists the definitions of the alarm severity levels and the handling measures.
Table 6-1Definitions of the alarm severity levels and the handling measures
Alarm Severity Level Definition Remark
Critical The critical alarm
indicates that the fault
affects the system
service. Therefore,
you must handle the
alarm immediately
even though the alarm
occurs during non-
working hours. For
example, if an alarm
occurs regarding theunavailability of the
device or the
resource, take
immediate measures
to clear the alarm.
This alarm must be cleared immediately.
Otherwise, the system breaks down.
Major The major alarm
affects the service
quality. You must
handle the alarm
during working
hours, for example,the alarm regarding
the degraded service
quality or unavailable
resources. Otherwise,
some important
functions cannot be
realized. Therefore,
take immediate
measures to clear the
alarm.
This alarm must be cleared immediately.
Otherwise, some important functions
cannot be realized.
Minor The minor alarm doesnot affect the service
quality. To avoid
severe damage,
handle the alarm
properly.
The minor alarm can remind themaintenance personnel of locating the
alarm cause and eliminating the hidden
troubles.

The warning alarm requires only the
general knowledge of the running state
of the device.
6.1.3 Categories of Alarm Events
The event alarms can be triggered by the following: power system, environment system,
signaling system, trunk system, hardware system, software system, running system,
communication system, service quality, and processing error.
l Power system alarms concern the power system.
l Environment system alarms concern the environment of the equipment room such as
temperature, humidity, and access control.
l Signaling system: alarms concern the signaling system.
l Trunk system alarms concern the trunk circuit or trunk board.
l Hardware system alarms concern the hardware such as the clock and CPU.
l Software system alarms concern the software.
l Running system alarms concern the running system.
l Communication system alarms concern the communication system.
l Service quality alarms concern the service quality.
l Processing errors concern alarms caused by other abnormalities.
6.1.4 Alarm Box

alarms are cleared, the indicator is constantly on. You can manually switch off the indicator on
the LMT.
Meaning of Alarm Indicators
The alarm indicators with different colors represent different severity levels.
l The red indicator represents critical alarms.
l The orange indicator represents major alarms.
l The yellow indicator represents minor alarms.
l The green indicator represents warning alarms.
6.2 Browsing Alarms
