DHCP Naming
A DHCP name is a unique identifier used for managing multiple DHCP hosts on a
network. Your unit ships with a default DHCP name of Cxxxxxx, where xxxxxx is the

server in Setup Mode. Change the DHCP name to LTXdd, where 0.0.0.dd is the IP
address assigned (dd should be a number between 1 and 99). For example, if the IP
