System Maintenance

8.1 Routine Maintenance Overview

Definition

Routine maintenance is scheduled maintenance carried out to ensure proper

system operating and avoid any unscheduled breakdown and downtime.

Routine Maintenance Precautions

●

Routine maintenance is critical to the normal operation of a device. Perform

routine maintenance regularly. Read all the precautions and product

documentation before performing maintenance.

●

Follow local laws and safety instructions to minimize the risk of personal

injury and damage to devices.

●

The "NOTICE", "CAUTION", "WARNING", and "DANGER" statements in this

document do not represent all the safety instructions. They are only

supplements to the safety instructions.

●

Personnel who plan to install, operate, or maintain Huawei devices need to

receive a thorough training, understand all necessary safety precautions, and

be able to correctly perform all operations.

●

During operation, comply with the safety symbols on the device and all the

safety instructions in this document. The safety precautions provided in this

document do not cover all the safety precautions. Huawei shall not be liable

for any consequence caused by the violation of the safety operation

regulations and design, production, and usage standards.

●

Most maintenance tasks need to be performed with power off. Do not

connect the power supply during maintenance. If you need to perform

maintenance tasks such as measuring the current, voltage, and temperature

when the device is operating, connect the power supply only after you have

connected all cables. Disconnect the power supply when you finish

maintenance.

●

Protective measures, such as wearing insulation gloves or shoes, must be

taken during electrical maintenance.
