DHCP/BOOTP Problems

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.

Language Problems

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

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.

Long Reboot Cycle

Rebooting the IOLAN takes a long time.

If you are not using DHCP/BOOTP, disable this within the Server Services; otherwise, the IOLAN waits to timeout for a request to DHCP/BOOTP.

I/O Models

An I/O Digital or Relay controlled motor is starting/stopping

zDigital and Relay channels have automatically resetting fuses, meaning that if the circuit gets overloaded and the fuse blows, it will automatically reset when the circuit cools down.

An A4R2 model is starting/stopping

zThe A4R2 model can run at 55 degrees Celsius ambient temperature when the input voltage is 22VDC or below. If the input voltage exceeds 22VDC, the maximum ambient temperature will drop into the range of 45-50 degrees Celsius to run successfully.
