Unknown IP Address

Unknown IP Address

You have already configured the IOLAN and you do know your password, and have lost, misconfigured, or don't know the IP address of the IOLAN, so you cannot obtain a successful login.

zIf the IOLAN resides within the local network segment, you can use DeviceManager to find the

IOLAN.

zYou can connect directly to the serial port of the IOLAN, as explained in Using a Direct Serial Connection to Specify an IP Address on page 67.

DHCP/BOOTP Problems

Messages: host name too long or filename too long.

zThe IOLAN can only accept host names of 14 characters or file names of 64 characters, so verify that you are not attempting to pass a string that is longer than those maximums.

DHCP or BOOTP have been set up to configure my IOLAN, but does not seem to have done anything.

zCheck that the server DHCP/BOOTP service is set to on, if not set it to on and reboot.

zCheck that your BOOTP server is configured for your IOLAN or that your DHCP server has an active lease pool (scope) with at least 1 free IP address.

You observe TFTP errors when the IOLAN boots, for example:

TFTP: File not found : filename

TFTP: Timed out

This has a number of causes, including:

zThe file names you specified to DHCP/BOOTP do not exist or are in the wrong place.

zThe server for any of the downloadable files in your bootfile has no TFTP server running.

zVerify that lease data in your DHCP server manager is correct.

zReset or restart the DHCP server.

Callback Problems

User Callback is On, and a number is configured for the line, but the IOLAN is not calling the user back:

zVerify that the phone number is entered under the user (not the line).

zVerify that the callback Phone Number is valid.

zVerify that the modem at the user’s end is set to ‘auto-answer’.

Language Problems

In a customized language, the text strings appear in the wrong place in the Menu, CLI, or WebManager.

zCheck the original ASCII text file you used to translate to your customised language. The sequence of the line much match exactly (be aware that comments don’t affect line sequence, but can affect the actual line that the strings appear on). So, if you strip out all comments, if the original file says line 1000 should be string none, then line 1000 (stripped of comments) should be the translated version of none.
