VES-1000 Series Ethernet Switch
Troubleshooting 15-3
Table 15-F Troubleshooting the Password
STEPS CORRECTIVE ACTION
1 Upload the default configuration file (see section 3.4.1 and Chapter 10 ). All settings will return to the
default value and previously saved configurations will be lost.
2 Send a screen shot of your VES-1000 Series switch’s MAC address to your local distributor.
15.7 Remote Server
The computer behind the VDSL modem or router cannot access a remote server.
Table 15-G Troubleshooting a Remote Server
STEPS CORRECTIVE ACTION
1 See Table 15-B to make sure that you are able to transmit to the VES-1000 Series switch.
2 Make sure the gateway’s IP address is the same as the one configured in the user’s computer.
3 Check the VLAN configuration of the Ethernet port on the VES-1000 Series switch (see section 13.4).
4 Check the Ethernet cable and connections between the VES-1000 Series switch and the gateway.
5 Try to access another remote server.
If data can be transmitted to a different remote server, the remote server that could not be accessed may
have a problem.
15.8 Telnet
I cannot telnet into the VES-1000 Series switch.
Table 15-H Troubleshooting Telnet
STEPS CORRECTIVE ACTION
1 Make sure telnet service is not disabled in menu 24.11.
2 Check that the IP address(es) in the Secured Client Sets menu (menu 24.11.1) match the client IP
address(es). If they do not match, the VES-1000 Series switch will disconnect the telnet session
immediately.
3 Check that there is not an SMT console session running.
4 Make sure that a telnet session is not already operating. The VES-1000 Series switch will only accept one
telnet session at a time.
5 Ping the VES-1000 Series switch from your computer.
If you are able to ping the VES-1000 Series switch but are still unable to telnet, contact the distributor.
If you cannot ping the VES-1000 Series switch, check the IP addresses in the VES-1000 Series switch and
your computer. Make sure that both IP addresses are in the same subnet.
6 If you are attempting to telnet from the VDSL side of the VES-1000 Series switch, see Table 15-B to make
sure that you can transmit data to the VES-1000 Series switch.
7 If you are attempting to telnet from the Ethernet side of the VES-1000 Series switch, check the Ethernet
cable.
