Preface

Purpose NetNumen M31 mobile network element management system isthe intermediate system between the bottom level network man-agement system and higher level operation support layer. Thissystem provides a higher view point for the network management,and offer a centralized management to the various specialized net-works. By interfacing with various professional network manage-ment system, this system provides a new method of centralizedmanagement over the networks topology, alarming and perfor-mance which replaces the old distributed individual managementof specific networks. Also an unique interface to higher level ap-plications is provided.

NetNumen M31 is completely based on object-oriented technol-ogy and advanced J2EE platform. It supports an unified access ofthe various network element equipments supplied by ZTE and pro-vides centralized management to the networks alarming, networkperformance, and cross-NE performance data analysis.

This manual introduces the alarms and notifications that mightoccur during the installation, operation and maintenance of ZTEZXSDR BS8800 U240 product. Alarm/Notification code and de-scription displayed by NetNumen M31, probable cause for thealarm/notification, and the corresponding handling suggestion arecovered in this manual.

Overview of FaultManagementFault management is responsible for collecting information of fail-ures and events that occur during system operation or service pro-cessing.

The information, in the form of alarm or notification, is stored indatabase or displayed on realtime basis via a user-oriented faultmonitoring platform. Means such as visual-interface monitor orhistory information query can be used to view current or histor-ical system operation and service processing status. Fault man-agement enables maintenance personnel to troubleshoot and takepreventive measures to remove potential fault and restore systemand services as early as possible.

Fault ViewFault is displayed in the form of alarm or notification.

Alarm

The fault that persists during system operation and affects systemreliability and normal services is referred to as an alarm. Alarmusually lasts until fault removal.

Due to its possible impact on normal system operation, alarm re-quires timely troubleshooting in which alarm cause is identified,and the fault is located and handled.

Notification

Notification refers to the non-repeated/instantaneous fault orevent that occurs during system operation. Examples includeboard reset, signaling overload, etc.

Notification is mostly caused by sudden environment changeor other accidental factors. No special handling is required forthe notification, which can be automatically removed by thesystem. Only the notification that occurs persistently requirestroubleshooting.

Alarm Information StructAlarm Property 1. Alarm Code

Alarm Code is the identifier which differentiates alarms.

Alarm Code is defined by a 32-bit field indicating the specificcode value.

2. Description

Alarm description reflects such content as fault cause and faultphenomenon in a simple and straightforward way.

3. Severity

There are four alarm levels, which are indicated in descendingorder of severity as Critical, Major, Minor, and Warning.

Critical alarm causes system breakdown and service inter-ruption. It requires immediate troubleshooting.

Major alarm significantly affects system operation or weak-ens network service capability. It requires troubleshootingas soon as possible.

Minor alarm affects system operation and network servicecapability in a non-significant way. It requires timely trou-bleshooting so as to avoid severity escalation.

Warning poses a potential hazard to system operation andnetwork service capability. It requires troubleshooting atan appropriate time so as to avoid severity escalation.

The degree of impact as described in the definition of alarmseverity refers to the impact of a single index, such as reliabilityand security. Once the impact on any of the index reachesthe specified threshold, the severity level of the alarm can beroughly determined. If an alarm has an impact on multipleindices, alarm severity should be escalated accordingly.

Chapter 1 Overview

Note:

Alarm severity can be modified in NetNumenM31 NMS (net-work management system) if necessary.

Generally speaking, the default alarm severity is reason-ably set. Users should think twice before making any mod-ification.

In addition, the severity of a few alarms is undefined. It is upto users to define the severity of such alarms.

Alarm Type: Equipment Alarm

Probable Cause 1. Primary channel over-power alarm:

this alarm is given when the detected maximum output powerexceeds 47.3dBm 0.5dB. In this case, Tx channel works inbypass state.

2. Primary channel over-VSWR alarm:

when the value of VSWR exceeds 1.8, only an alarm is given,auto-protection shut-down function is not required. When thevalue of VSWR exceeds 2.8 and output power is greater than35dBm, an alarm is given; meanwhile, auto-protection shut-down function is required. In this case, Tx channel works inbypass state.

3. Primary channel over-temperature alarm:

TMB has its own temperature detection function. When itsinternal maximum working temperature exceeds 95 degreesCelsius 5 degrees Celsius, this alarm is given. In this, Txchannel works in bypass state.

4. Primary channel DC over-current alarm:

when the DC current exceeds 150% of normal working current,this alarm is given. In this case, Tx channel works in bypassstate.

5. Primary channel device fault alarm:

for example, working voltage is out of -40VDC~-57VDC range,PA is broken. In this case, Tx channel works in bypass state.
