HP SUM requires that certain network ports are available for proper operation. If you lock down network ports, remember to ensure that the ports listed in the network port tables are open so that HP SUM works correctly when connecting to remote target servers and hosts. If you are unable to unlock these network ports, the only option is to run HP SUM locally and update network-based hosts, such as the OA, iLO, and VC, through their web interfaces.

You can define your own ports by modifying the hpsum.ini file.
