Page 7: Hardware Recommendations
Basic Network Considerations OpenManage Network Manager communicates over a network. In fact, the machine it is on must be connected to a network for the application to start successfully. Firewalls, or even SNMP management programs using the same port on the same machine where this software is installed can interfere with communication with your equipment. -

Multicast. Fixed IP Address OpenManage Network Manager includes a web server and must be installed to a host with a fixed IP address or a permanently assigned Dynamic Host Control Protocol (DHCP) lease. For trial purposes, you can rely on a dynamic IP address assignment with a long lease, but this is not recommended for production installations. -
Page 9: Updating Your License
Updating Your License If you have a limited license — for example OpenManage Network Manager by default limits discovery to ten devices — then your application does not function outside those licensed limits. If you purchase additional licenses, put the updated license file in a convenient directory, then use the Settings ->... -
