3.2 Operation and Maintenance Methods
The following maintenance methods are used for troubleshooting:
Checking Alarms and Operation Logs
This is the most common method for troubleshooting.
Method: Check the alarm management and operation log windows in the operation and
maintenance system.
In the alarm management window, you can observe and analyze the alarms reported
by NEs, such as current alarms, historical alarms, and notifications, discover abnormal
network operation, and locate, isolate, and eliminate faults in time.
By checking the operation logs in user management, you can trace system parameter
modification, locate relevant terminals and operators, and discover the faults caused
by manual operations.

Chapter 3 Applications and Maintenance
Performance Analysis
Method: Check the performance management window in the operation and maintenance
system.
In the performance management window, you can create performance management
tasks and generate performance reports to understand the NodeB system performance
indicators.
By analyzing the information, you can learn about load allocation and other network
conditions, and modify relevant performance to improve network performance.
Instrument and Meter Analysis
Auxiliary instruments, such as test UE, signaling analyzers, and bit error analyzers, can
be used for troubleshooting.
Replacement
You can replace a faulty part with a spare part or a similar part that operates properly in
the system to locate a fault.
For the operation methods, refer to the ZXSDR BS8922 TD-LTE Integrated Micro Base
Station Engineering Installation Guide.
Self-Test
The system performs a self-test when it is powered on again.
During the self-test, the indicators flash in accordance with relevant rules. You can locate
faults by checking the indicators.
Integrated Method
In actual operation, all the methods can be used for troubleshooting.

FCC&IC STATEMENT
This device complies with Part 15 of the FCC Rules. Operation is subject to the following
two conditions:
1. This device may not cause harmful interference.
2. This device must accept any interference received, including interference that may
cause undesired operation.
Note:
This equipment has been tested and found to comply with the limits for a Class A digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference when the equipment is operated in
a commercial environment. This equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in accordance with the instruction manual,
may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful interference in
which case the user will be required to correct the interference at his own expense.
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment.
This equipment should be installed and operated with minimum distance 1.6m between the radiator & your body.
