Before performing maintenance, conform to the following recommendations:
Keep the device clean and dry.
Perform regular checks and tests according to the daily maintenance procedures and
record related data.
Quickly resolve any problems found during the maintenance process. When facing
problems that cannot be resolved, contact Huawei local representative office.

accounts only to maintenance personnel. The password of the management account is
only known to the maintenance owner.
