1.1 Positioning

This product description is oriented to the battery intelligent management system (eBIMS)

V100R002.

Batteries, an indispensable part of sites, are the O&M focus. The correctness of battery

performance management, timeliness of battery fault rectification, and fix rate of network

problems caused by battery faults have a large impact on network status. Therefore, low-cost

automatic detection and analysis for batteries become key requirements of the management

service center. The Huawei eBIMS fully meets battery maintenance requirements by remotely

monitoring real-time battery status, detecting, predicting, and reporting battery faults, and

identifying batteries reaching their replacement thresholds and guiding the battery replacement.

3.5 Alarm Management

Alarm management includes functions like monitoring, collecting, displaying, confirming,

clearing, and shielding device alarms, and querying historical events and alarms. These functions

facilitate fast discovery, location, and handling of network or device faults.

Alarms are classified into critical, major, minor, and warning alarms.

lCritical alarm: indicates that services have been affected and requires immediate

rectification measures.

lMajor alarm: indicates that services have been affected and severe results may occur if the

alarm is not handled in a timely manner.

lMinor alarm: indicates that services have not been affected but requires rectification

measures to prevent more severe faults.

lWarning: indicates that services have not been affected, but potential faults that will affect

services have been detected.

Displaying and Collecting Statistics on Alarms

The eBIMS real-timely monitors and receives alarms generated by managed devices, and

displays and collects statistics on alarms in various modes.

lAlarm panel

eBIMS

Product Description 3 Functions and Features

Issue 02 (2015-01-09) Huawei Proprietary and Confidential

–The alarm panel displays the alarm quantity and cleared alarms in the current alarm list

by severity.

lAlarm histogram

–The alarm histogram is an eBIMS window displaying alarms. The alarm histogram

displays alarms of the managed objects by severity in graphs and numbers.

Querying Alarms

The eBIMS supports view of current alarms and query of historical alarms, events, and

performance statistics. Alarms that users need to pay attention to and handle are displayed in

the current alarm list.

eBIMS

Product Description 4 Application Scenarios

Issue 02 (2015-01-09) Huawei Proprietary and Confidential

4.1 Overview

The eBIMS can be deployed inside an outdoor cabinet or indoor equipment room. An equipment

room can be a data center power battery room or a site equipment room.

lDeployment inside an outdoor cabinet

–eBats eMeter and eBox are installed inside the outdoor cabinet. The eBats are connected

to batteries and eMeter should be connected to the terminal of battery string, the eBox

is installed inside the cabinet using hook-and-loop fasteners. One eBox is installed for

each cabinet.

lDeployment inside a data center power battery room

–eBats eMeter and eBox are installed inside the indoor equipment room. The eBats are

connected to batteries and eMeter should be connected to the terminal of battery string,

multiple eBoxes are installed on a wall using screws. One eBox manages 250 wireless

module or sensors.

lDeployment inside a site equipment room

–eBats eMeter and eBox are installed inside the indoor equipment room. The eBats are

connected to batteries and eMeter should be connected to the terminal of battery string,

the eBox is installed on a wall using screws. One eBox manages 250 wireless module

or sensors.

NOTE

Currently, eMeter only can be used for battery sting with rated 48V voltage.

4.2 Application Scenarios

This section briefly describes the scenarios requiring the eBIMS and typical eBIMS deployment

scenarios.

Scenarios Requiring the eBIMS

Typical scenarios:

1. Outdoor sites encounter network problems because battery aging due to overcharge/

overdischarge/undercharge/underdischarge deteriorates backup time. In this case,

maintenance costs are increased because multiple site visits are required to confirm the

battery location and quantity, check battery performance, and determine whether to replace

batteries.

2. Routine testing and inspection of batteries inside equipment rooms require much human

power. Moreover, one-by-one battery check cannot accurately determine the battery status,

causing much waste.

Deployment Inside an Outdoor Cabinet

The eBats and eBox are deployed in an outdoor cabinet. They communicate with each other

wirelessly. The eBox transmits collected battery data to the server. Users log in to the server to

perform real-time monitoring and operations. This solution achieves real-time monitoring and

detection of battery status, predicts fault risks, and avoids futile site visits. Maintenance costs

are reduced. Figure 4-1 shows details of this scenario.

Figure 4-1 Deployment inside an outdoor cabinet

Deployment Inside a Data Center Battery Room

The eBats and eBoxes are deployed in a data center battery room. They communicate with each

other wirelessly. Multiple eBoxes transmit collected battery data to the server. Users log in to

the server to perform real-time monitoring and operations. This solution achieves real-time

detection of battery status and avoids onsite tests, saving costs. Moreover, this solution

accurately identifies batteries reaching their replacement thresholds, avoiding waste. Figure

4-2 shows details of this scenario.
