1.2 Routine Inspection-Purposes
The purposes of routine maintenance and inspection are as follows:
Find and remove the potential defects or hazards during device operating in a
timely manner. Take measures to rectify the faults to ensure normal device
operating and reduce the device fault rate.
Monitor the running status and trends of devices and networks in real time, which
improves the maintenance personnel's efficiency of handling emergencies.
Periodically maintain devices to ensure that devices run properly and that the
system runs safely, stably, and reliably.
Periodically check, test, and clean devices and back up data. This helps you find
the defects (such as natural aging, function disabling, and performance
deterioration) that occur during device operating. Take measures to handle the
defects to rectify potential faults and avoid accidents.

1.2 Routine Inspection-Basic Rules
Name a device uniquely.
Create logs for recording the troubleshooting.
Make one change at a time, and record the change result.
Use the tools, resources, and software provided by Huawei.
Be aware of the latest updates of the operating system (OS) and
applications.
Make a reliable backup plan.
Prepare spare parts onsite. Once a component is faulty, replace it with a
new one in a timely manner.
Keep the latest network topology, which helps rectify network faults.
