If there is a network problem, use the following procedure to troubleshoot whether the problem is with network hardware or software. All steps may not be required.
- Verify that the transceiver is connected to the network, client, and Teradata Database.
- Check for broken or disconnected network cables.
- Verify that drop cables are not too long. The cables must comply with IEEE 802.3 standards.
- Verify that all repeaters, bridges, routers, and gateways are functioning properly.
- Verify that all jumpers are setup correctly on the client's network controller board.
- Verify that the network software is installed and running properly on the client.
- Verify that the network software is compatible with the network controller board installed on the client.
- Confirm that the network is operational by using a network utility program.
- Use Basic Teradata Query or a network utility program from another client on the same network segment as the first client. If this works, there may be a problem with the first client.
- Use Basic Teradata Query or a network utility program from another client on a different network segment from the first client. If this works, there may be a problem with the first network segment.
- If a network controller board is replaced on the client, reboot Teradata Database so it can obtain the network address of the new board.
- If the network configuration was changed, check that all network related files were changed accordingly.
- Reboot the client to reset network hardware and reload network software.
