# Safety Information

Observe the safety information to ensure the normal operating of the ATIC.

#### Hardware Operations

- It is recommended to configure an independent uninterrupted power supply (UPS) for the ATIC server, protecting the hardware, system, and data from unexpected power failure. If the ATIC server is not configured with the UPS, the administrator must properly close the ATIC process, database, and power one by one before the power cut after receiving the notice for upcoming power cut.

- To shut down the ATIC server, you must follow the proper shutdown method in all situations. Do not switch off the hardware power directly to shut down the ATIC server; otherwise, the system recovery failure will be caused.

- It is recommended to check the network communication every day according to the daily maintenance items to protect the network communication from disruption.

- Do not remove the network cable from the server at will when the ATIC is running. If you really need to remove the network cable, stop the ATIC service first.

#### Software Operations

- Do not install unnecessary software on the ATIC server.

- Do not use the ATIC server to browse Web pages. Do not set unnecessary sharing directory. Ensure that the permission on the sharing directory is specified.

- Do not connect other computers to the network where the ATIC server resides to avoid IP address conflict and virus infection.

- Set the properties of the OS, database, and ATIC passwords by level, and assign the passwords to the maintenance owner only. Only the maintenance owner has the administrator password. Passwords should be strictly managed with clear properties.

- Check and test the ATIC periodically according to the maintenance item list and make a record of the check. After you discover a problem, handle it in time. For the problems that cannot be solved, contact the local office or customer service center in time to solve them.

#### ATIC Operations

- Do not change the system time when the ATIC is running. Set the system time before you install the ATIC.

  Shut down the ATIC server before you change the system time. Restart the ATIC server after the system time is changed. Do not set the system clock of the server ahead; otherwise, data mess will be caused.

- To log in to Windows, you must use the user name that was used to install the ATIC. Do no change the user name for logging in to Windows.

- It is recommended to synchronize NE data to the ATIC and query the latest NE data before you set parameters. During the use of the ATIC, ensure that data on the NE and that on the ATIC is consistent.

- Back up database periodically to minimize the system loss when errors occur.

- The ATIC will display a message for dangerous operations. Please notice such warnings.

- Do not set the NE to a language except Chinese and English; otherwise, the search results will be displayed as garbles on the ATIC interface.

- The administrator is prohibited from directly logging in to the OS to delete the data and log files of the database. Otherwise, the database-related issues cannot be located or traced.

- To prevent security vulnerability risks, upgrade the database to the latest version in a timely manner.
