13 Maintenance and Troubleshooting
Audio-Visual Cables
Periodically (once a week is recommended) check whether the cables connecting the terminal to the peripheral equipment and the power supply are securely connected.
If the cables are connected properly, power on the terminal to test the connectivity. If any of the cables are loose, connect them securely.
Communication Cables
Periodically (once a week is recommended) power on the terminal, and then check whether the communication cables connected to the terminal work properly using the following method:
Place calls to other terminals using different communication methods, such as accessing a broadband network.
If a call is set up successfully, it indicates that the communication cable works properly in the corresponding access mode.
If a call cannot be set up properly, check whether the cables are connected correctly and securely and whether the communication parameters are set properly. If the problem persists, contact the network administrator to check the network.
13.1.3 Viewing the System Status
To perform diagnostics against line connection, first view the network connection status.
To view the network connection status, do the following:
Step 1 Select Diagnostics from the home screen or press on the remote control.
Step 2 Select Status to view the following items:
Line status: You can view the IP address, gatekeeper status, network interface status, local site number, SIP information, and running duration.
Input interface status: You can view the information about the video input from the input interfaces of the terminal. For example, DVI/VAG IN DVI 720p 60 Hz indicates that the input mode, video resolution, and refresh rate of the DVI/VAG IN interface are DVI,
720p, and 60 Hz respectively.
3G network status: If the license supports the connection to a data card and if a data card is connected to the USB port of the terminal, you can view the current network, connection status, IP address, last connection time, and connection duration.
