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.

Alarm Severity Level Definition Remark

Warning The warning alarm

can indicate the

potential faults that

may affect services.

Take appropriate

measures to handle

the alarm.

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

Figure 6-1Alarm Box

Functions of the Alarm Box

The alarm box reports only those alarms that reach the threshold and are not shielded.

When the fault alarm occurs, the alarm box sounds. When the fault alarm is cleared, the sound

stops. You can manually mute the alarm box on the local maintenance terminal (LMT).

When the alarms of the same severity level occur, the related indicator flashes. When all those

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.
