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.

1.2 Routine Inspection-Onsite Inspection
Onsite inspection includes inspection of the equipment room environment
and device running status.
Icon Description
Indicates a hazard. To prevent an electric shock, do not remove the cover of the component.
Warning:All components with this icon have electric shock risks and there are no serviceable parts
inside these components.
Indicates a hazard. Operation of the component may cause an electric shock. There are no
serviceable parts inside the component, and therefore do not remove the cover of the component.
Warning:To prevent an electric shock, do not remove the cover of the component.
Indicates high temperatures.
Warning:Be careful and do not touch the component before it cools down. Otherwise, you may get
burnt.
Indicates a hazard. Misoperations may damage the device or cause personal injury.
Indicates the external grounding of the device. Both ends of a ground cable are connected to
different devices, and the devices must be grounded by connecting to ground points. This ensures
proper device operating and personal safety.
Indicates the grounding inside the device. Both ends of a ground cable are connected to different
components of a devices, and the device must be grounded by connecting to ground points. This
ensures proper device operating and personal safety.
Indicates an ESD-sensitive area. Do not touch the device with bare hands. When you operate a
device in an ESD-sensitive area, take ESD measures, such as wearing an ESD wrist strap or ESD
gloves.
