Method and apparatus for automatic IP allocation bootstrapping of embedded network management cards used in networked uninterruptible power supplies and other supported devices

摘要

The present invention relates to a Network Management Card enabling communications to supported devices, for example, an uninterruptible power supply (UPS) connected to a network. The Network Management Card operates to provide IP allocation according to BootP and DHCP processes, to automatically select an appropriate process, and apply it automatically and intuitively without specific operator interference or configuration. The Network Management Card further utilizes vendor specific codes in the DHCP process to limit the IP addresses assigned to UPSs in order to maintain information about the location of the UPSs on the network.
