Figure C-3. Example of Message for Download Failure

To find more information on the cause of a download failure, examine the messages in the switch’s Event Log. (See “Event Log” on page 5-11.)

Some of the causes of download failures include:

■Wrong protocol specified for the Protocol parameter

■Incorrect or unreachable address specified for the TFTP Server parame- ter. This may include network problems. Try pinging the server to test the connectivity.

■Incorrect name specified for the Remote File Name parameter, or the specified file cannot be found on the TFTP server. This can also occur if the TFTP server is a Unix machine and the case (upper or lower) for the filename on the server does not match the case for the filename entered for the Remote File Name parameter in the Download OS screen.
