Precautions

Perform the following precautionary steps during routine maintenance.

Maintain normal temperature and humidity in the equipment room. Keep the equipment room environment clean and tidy and free from dust and dampness. Prevent rodents from entering the equipment room and cabinets.

Make sure that the primary power supply is stable and reliable. Check the system groundings and lightning protection groundings periodically. Check and ensure good condition of lightning protection system before and after the thunderstorms.

Standardize the daily work of maintenance personnel:

Maintain a detailed attendant’s log to provide records about system operation, version, data change, upgrading and troubleshooting. It facilitates analysis and troubleshooting after fault detection.

Keep a record of work shifts and specify the responsibility clearly.

Install anti-virus software at each client. Do not disable the real-time detection function. Update the virus library periodically. Do not use unauthorized disks or CDs. Do not install and run software unrelated to maintenance work.

Only one user can have the super administrator right. The super administrator sets different Network Management passwords for different access rights. The rights of login into server and client should be graded. Passwords should be managed strictly and changed periodically.

Maintenance personnel should be well trained and should have adequate equipment and network knowledge. Wear an anti-static wrist strap before touching any equipment hardware to avoid accidents.

Do not plug/unplug, reset, or change over boards casually. Backup data before doing any data modification, and make records of data modifications. Do not delete backup data until the equipment has run properly for a period of time (usually a week) after data modification. Even if there is no data modification, backup the database periodically, and restore the data in time for emergency requirement. Databases, especially the performance measurement and



alarm database, should be observed on a regular basis to check whether the automatic dump function is normal in order to avoid the error of disk overflow.

Do not run the signaling trace during busy-traffic hours, especially at daytime. The signaling trace can be performed only during low-traffic hours with the permission of local ZTE office.

Keep common tools and instruments available in the equipment room. Such tools and instruments include flathead screwdriver and cross screwdriver, signaling tester, network cable pliers, multimeter, AC power supply, telephone line, network cable, antistatic wrist strap, insulating tape, and common toolkit. Check and ensure the precision of instruments and tools periodically.

Check spare parts periodically to maintain accurate inventory of frequently used spare parts to ensure their working conditions. Ensure that the inventory contents are unaffected by moisture or mould. Keep spare parts and the replaced faulty parts in antistatic bags separately and label them appropriately for identification purposes.

Keep maintenance software and documents at designated position, to ensure that they are available when necessary

Make sure that lighting in the equipment room is bright

Remove any detected faults as soon as possible. For faults that can not be resolved, contact the local ZTE office, and record the troubleshooting procedure in details.

Put the contact information of the local ZTE office in a noticeable place, and notify it to all maintenance personnel so that ZTE can be contacted when there is a need. Update the contact information as soon as possible if there is any change.
