Definition of Routine Maintenance
Routine maintenance is a kind of active maintenance. It is
also called preventive maintenance or periodic
maintenance.
Routine maintenance is performed periodically during
normal operation of equipment, including daily, weekly,
monthly, quarterly, and yearly routine maintenance.
HUAWEI TECHNOLOGIES CO., LTD. Page 6All rights reserved
Objectives of Routine Maintenance
Remove potential risks to ensure the system works normally.
Ensure that the electrical performance, mechanical
performance, and various service indexes of equipment
conform to relevant requirements.
Guarantee the network runs normally by good coordination.
Make sure that the new equipment and expansion equipment
to be connected to the network correctly.

Current Alarm and History Alarm
Current Alarm: The current alarm refers to a fault alarm or an
event alarm that has not been recovered or acknowledged .
History Alarm: All alarms generated in the system, including
fault alarms and event alarms, when they are recovered or
confirmed are called history alarms.
HUAWEI TECHNOLOGIES CO., LTD. Page 19All rights reserved
Querying Alarm by Commands
LST ALMFE
This command is used to query the current alarms (including fault alarms and ev
ent alarms) in the system and returns a maximum of 100 results .
Example:
− LST ALMFE : CNT=100;
LST ALMLOG
This command is used to query history alarms of BSC.
Example:
Query the history alarms of BSC, alarm level: critical and major alarms. Up to 2
00 records will be returned when the alarm level are “Critical” and “Major” f
or history alarm query.
− LST ALMLOG: ALMTP=flt, ALVL=EMERGENCY-1&IMPORTANT-1&CO
MMON-0&NOTIFICATION-0, CNT=200;
HUAWEI TECHNOLOGIES CO., LTD. Page 20All rights reserved
Querying Alarm by Commands
LST ALMINF
With this command we can query the detailed information of one alarm with the specific alarm serial No.
Example:
Query the alarm which serial No. is 2200.
− LST ALMINF: CSN=2200;
LST ALMCFG
This command is used to query the configuration information of the alarms which IDs are between start ID and end ID.
Example:
Query the alarms with the IDs between 100 and 200.
− LST ALMCFG: STARTAID=100, ENDAID=200;
HUAWEI TECHNOLOGIES CO., LTD. Page 21All rights reserved
Managing Alarm by Commands
RMV ALMFLT
This command is used to recover the specific alarms manually.
Example:
Recover all the alarms which serial No. are between 111 and 222.
− RMV ALMFLT: STARTCSN=111, ENDCSN=222;
RMV ALMLOG
This command is used to delete history alarms generated during the
days you define on LMT.
Example:
Delete all the history alarms between 2005-05-03 and 2005-05-05.
− RMV ALMLOG:SD=2005&05&03,ED=2005&05&05;
HUAWEI TECHNOLOGIES CO., LTD. Page 22All rights reserved
Managing Alarm by Commands
SET ALMACK
This command is used to confirm alarms with the serial No. between the
specific range.
Example:
Confirm the alarms with the serial No. between 2000 and 2100.
− SET ALMACK: STARTCSN=2000, ENDCSN=2100;
SET ALMLVL
This command is used to set the alarm levels.
Example:
Set the alarm level as “Major” for alarms which ID is between 100 and 200.
− SET ALMLVL: STARTAID=100, ENDAID=200, NEWALVL=IMPORTANT;
HUAWEI TECHNOLOGIES CO., LTD. Page 23All rights reserved
Managing Alarm by Commands
SET ALMMSK
This command is used to shield alarms between the specific ID range you set
on LMT.
Example:
Shield the alarms with IDs between 50 and 80.
− SET ALMMSK: STARTAID=50, ENDAID=80, MSKFLG=MASK;
The system will not store and display the shielded alarms.
SET CLTRPT
This command is used to set alarms not to be reported to the client.
Example:
Set alarm with the ID as 100 not to be reported to the client.
− SET CLTRPT: AID=100, RPTFLG=NONRPT;
HUAWEI TECHNOLOGIES CO., LTD. Page 24All rights reserved
Difference Between SET ALMMSK & SET CLTRPT
If SET ALMMSK is executed, the foreground will not stored
corresponding alarms. And the alarms could not be queried by
command “LST ALMLOG” or “LST NEALMLOG”, but the execution
result of “SET CLTPRT” is not in this case.

Maintaining Alarm Box
Check the serial port communication indicator on the alarm box.
Check the status of alarm indicator to see if it conforms to the actual situation.
Check whether the alarm tone can be set correctly.

Checking Communication Status of the BAM and EWS
EWS (Emergency WorkStation) backs up important data such as
BAM database automatically. They take over tasks of the BAM
temporarily in the case of BAM server failure. Therefore, we must
make sure that the BAM communicates with EWS normally.
If the BAM communicates with an EWS normally, we can ping the IP
address of the EWS from the BAM, otherwise, we should check:
Network cable connections between the BAM and local area
network (LAN) Switch
Network cable connections between the emergency workstation
and LAN Switch
Settings of the network adaptor
HUAWEI TECHNOLOGIES CO., LTD. Page 45All rights reserved
Checking Auto-Backup Data of the System
To ensure the security of database on the hard disk of BAM server, the system starts a scheduled task after its start-up by executing the command BKP DB automatically to back up BAM database, alarm database, and License files every early morning.
Check whether the following files for the latest three days exist under F:\cdma2000\backup at the BAM and its emergency workstation:
BamYYYYMMDD.dat
AlarmYYYYMMDD.dat
cbsclicenseYYYYMMDD.dat
CSWSYYYYMMDD.dat
BamRegYYYYMMDD.bak
cdma2000YYYYMMDD.ini
HUAWEI TECHNOLOGIES CO., LTD. Page 46All rights reserved
Dumping System Data Periodically
To ensure the safety of system data, you should weekly dump
the system backups on the hard disk of BAM server to other
storages so that the system can be recovered immediately in
the case of emergency situation.
You need to dump all files under the directory F:\cdma2000\
backup including database files, registry files, and system
configuration files.
You can select backup modes according to actual situations. It
is suggested to save backups onto hard disks of other
computers on the network.
HUAWEI TECHNOLOGIES CO., LTD. Page 47All rights reserved
Purging Useless BAM Data
In routine maintenance of BAM system, we should periodically
purge useless files on the BAM hard disk to release the hard
disk space. In this way, we can store important system data
timely and effectively.
Useless files on the BAM hard disk include:
Programs and data of earlier version backed up before
system upgrade or patching
Files under temporary folders created in daily maintenance
