In this example, the menu is viewed from system A as indicated by the small box around the letter “A”.

The X’s for the Ready and Active lights on system B indicate that status information is unavailable because of a communication failure of the RCP–to–RCP link.

Problem

RCP–to–RCP link has failed, or RVPB has been turned off.

Action

Check RCP–to–RCP link cable:

  1. Check the front panel.
  2. Check the Radar Status Menu for system B (”RCP Dead” in Subsystem Status).
  3. Start the Switching Menu on system B and check the 4 Xs.
