Enhanced Redundancy II board (51306803-100) for the Application Module. EAMR II

The Application Module Redundancy Subsystem includes two Application Module nodes that are cable-connected through EAMR or EAMR II boards and a K4LCN processor.

AM Redundancy includes hardware and software that allow a secondary EAMR II to back up the operation of the primary EAMR II. To do this, all of the application data in the primary EAMR II is transferred to the secondary EAMRII, where an exact copy of the data is maintained to be used if the primary AM should become inoperative.

EAMR II extended redundancy board (51306803-100-100) that connects to the K4LCN-16 board through a ribbon cable that is visible at the front of the chassis. The EAMR I/O boards EAMR I/O CE CE Compliant and EAMR I/O Non-Ce Compliant in each AM are interconnected by two ribbon cables that are visible at the rear of the chassis.

Power must be removed from the module whenever you are removing or installing any board, including an I/O paddle board. Be sure that an I/O paddle board is installed in the correct slot; some boards have only one slot that they can be installed in without causing damage. I/O paddle boards plugged into the wrong slot can cause traces on the backplane to burn open.
