This read-write enumerated integer reports and controls the connection state of the board immediately to the right (board n-1) on the Flexible Network Bus: detached(1) for management-only detachment, attached(2) for both management and AutoMode attached, or faulted(3), read-only, indicating a failed attach attempt. An administrator uses this to manage or diagnose the FNB interconnect on the opposite side from fnbConnectLeft. For example, when a board fails to communicate over the bus with its right-hand neighbor, the admin checks this object and finding it faulted(3) confirms the attach attempt to that neighbor failed.
