Abstract
Described is a network element for a communications network. Management communications with the network element occur using a single IP address. The network element includes two shelf processors each having a negotiations module. One of the shelf processors has a master status and the other shelf processor has a slave status. A backplane in communication with the shelf processors allows the negotiations modules to exchange data and to determine whether one of the shelf processors has experienced a fault. If a fault is determined in the master shelf processor, the slave shelf processor becomes the master shelf processor and the master shelf processor becomes the slave shelf processor.
