DNZUPX103E: The TFTP server cannot start.The TFTP server port VALUE_0 was disabled by the server's security policy. <p>Some I/O modules require that firmware be updated using Trivial File Transfer Protocol (TFTP), which is considered to be a non-secure protocol. Therefore, the TFTP protocol cannot be used by the Flex System Manager management node to update firmware on an I/O module while the security policy set for the Flex System Manager management node is set to Secure (the default). </p> <p>Although you can change the security policy on the Flex System Manager, a better alternative is to install a TFTP server and use that server via the "Use the following system as a TFTP server:" option below to update the firmware for the I/O module.</p> <p>For more information about accessing a TFTP server from the IBM Flex System Manager management node, click the I/O modules - Check and Update Firmware link on the Home tab of the IBM Flex System Manager user interface. Then, click the link for Information on configuring access to I/O modules.</p> <p>See the documentation that is provided with the I/O module for more information on using a TFTP server to update I/O module firmware.</p>

Explanation: The TFTP server port was disabled by the server's security policy.

Operator Response: Use a TFTP server on another system or lower the level of the server's security policy, then retry the operation.
