Abstract
Aspects of the invention provide apparatuses, systems, and methods for supporting cable redundancy in a network connecting a network controller () and an I/O device () (an adapter). An adapter includes a first port () and a second port () for receiving the same messages from a scanner () over a first and second transmission media (), respectively. A connection manager module () instructs a switching module () to direct the output data contained in the first message to a data structure () when the first transmission medium is operational and to direct the output data contained in the second message to the data structure when the first transmission medium is non-operational. Also, the adapter formats a message from input data. The connection manager instructs a switch () to direct the message to a primary port () when a primary transmission medium () is operational and to direct the message to a secondary port () when the primary transmission medium () is non-operational.
