Chapter 1

Overview Functions of Fault Management The fault management system collects fault information from all the NEs in the managed network in near real-time, such as boards, links, databases, and servers, and then displays the collected fault information in the format of alarm or notification. The fault management system helps the system administrator quickly locate and resolve faults in the managed network. It also provides telecom operators, network management departments, and equipment vendors with correct and timely alarm data to ensure stable network operations.

Fault Indication The fault management system indicates a fault or event occurring in the network in the form of alarm or notification. l

l

A fault is indicated in the form of alarm when it persists and affects the reliability and services of the system. An alarm will be cleared only after the fault is resolved. Immediate troubleshooting is required when alarms occur. A notification indicates a non-repeatable or instantaneous fault or event in the system, for example, board reset and signaling overload. Such a fault or event is normally caused by a sudden environment change or other accidental factors. No special handling is required because the fault or event causing a notification can be automatically handled by the system. However, a frequently-reported notification requires troubleshooting.

Alarm Format The alarms defined for the NR8120are provided with the information such as property and possible causes. For details, refer to Table 1-1. Table 1-1 Alarm Format Description Item

Description

Alarm Code

Description

Alarm Level

There are four alarm/notification severity levels, which are indicated in descending order of severity as Critical, Major, Minor, and Warning. l

Critical: indicates a fault that causes failures of system operations or service capabilities. Immediate troubleshooting is required when a critical alarm is reported.

l

Major: indicates a fault that seriously impacts proper system operations or reduces service capabilities. Clearing the fault to restore the system as soon as possible is required when a major alarm occurs.

l

Minor: indicates a fault that slightly influences proper system operations or reduces service capabilities. Proper measures should be taken to clear the fault in a timely manner and prevent the occurrence of more severe alarms when a major alarm occurs.

l

Warning: indicates a fault that has a potential or gradual impact on proper system operations or service capabilities. Warning messages need to be analyzed and proper measures should be taken to clear the fault in a timely manner and avoid more severe alarms.

The impact degree described in the definition of alarm severity refers to the impact on a single index, for example, reliability or security. Once the impact on any index reaches the specified threshold, the severity level of the alarm can be roughly determined. If an alarm has an impact on multiple indices, its severity level should be escalated accordingly. Alarm Type

Based on the triggering condition and system impact, alarms/notification can be classified into the following five types: l

Equipment alarm: related with equipment hardware faults.

l

Communication alarm: related with information transmission faults (ITU-T Recommendation X.733).

l

Processing error alarm: related with software or processing faults (defined in ITU-T Recommendation X.733).

l

Environmental alarm: related with the environment where the equipment is located (defined in ITU-T Recommendation X.733).

l Probable Cause

QoS alarm: related with equipment operation performance or indexes.

Provides probable alarm/notification causes to help users troubleshoot, find preventive measures, and restore the system to normal state in a timely manner.

System Impact

Provides the consequence of each alarm/notification and the impact on the system and services.

Description

Handling

Provides the troubleshooting steps and suggestions.

Suggestion

During the alarm handling process, the following tips needs your attention: l

After recording the fault information, O&M personnel needs to handle the fault step by step as suggested. If there is no otherwise specified and the fault is solved (that is, alarm is cleared), the alarm handling process ends. If the fault persists, go to the next step.

l

If fault cannot be removed, contact the local ZTE office.
