6.2 Network errors
6.2.1 Web interface and FTP server not accessible
The gateway web interface and the FTP server are not accessible.
1. Run CHIPtool and check if the gateway appears in the list (see 2.2.1
CHIPtool).
- If the gateway is not visible in CHIPtool, continue to 6.2.2
No network connection.
- If the gateway is visible in CHIPtool, run a connection test (ping).
- Try to access the FTP server from CHIPtool.
2. If the gateway responds to ping and can be accessed with the FTP client in CHIPtool, but is not
accessible from a browser or an external FTP client, check that the gateway is within your net-
work subnet (see 2.2
Network configuration) and that it is not blocked by firewall settings.
If you are unsure, contact your network administrator.
3. If the web interface start page is visible but the default user is not logged in, check if you can log
in using admin credentials. You can also try clearing the web browser cache (see the documen-
tation for your browser).
6.2.2 No network connection
The gateway cannot be accessed and is not visible in CHIPtool.
1. Check the physical connection (cables and connectors).
- Check that the link LED on the Ethernet port of the gateway shows an amber light and the
activity LED is flashing green.
- Check the corresponding LEDs on the remote terminal (PC, switch, etc.).
- If necessary, replace the cables and try again.
2. If the gateway still does not appear in CHIPtool, check that communication is not blocked by a
firewall. If you are unsure, contact your network administrator.
3. If the gateway appears in CHIPtool, run a connection test (ping).
If no ping reply is received and the gateway is connected via a local network, try using a direct
network connection to the PC instead.
Using a direct connection between the PC and gateway, the following example IP configuration
can be used. No other network gateways must be connected to the PC except the gateway.
A cross-over Ethernet cable may be needed for a direct connection between the
gateway and a PC.
