E-4        Switch Setting Reference

      Regardless of this switch setting, outputs are turned off when any of the following occurs:

processor detects a major fault
an I/O chassis backplane fault occurs
you select program or test mode
you set a status file bit to reset a local rack

      If a memory module is not installed and processor memory is valid, the processor’s PROC LED

   indicator blinks, and the processor sets S:11/9 in the major fault status word.  Power down the processor
   chassis and either install the correct memory module or set switch 6 ON.

      If the processor’s keyswitch is set in REMote, the processor enters remote RUN after it powers up and has

   its memory updated by the memory module.

      You cannot clear processor memory when this switch is on.
