Control processor failure (nonredundant HPM)
A Control processor failure of a nonredundant HPM (after transitioning to the Idle or Run state) results in
a sequencing display of
IDLE
or
OK
alternating with FCTL. If the Detailed Display mode (switch) is
enabled, a failure code is displayed in the sequence. The following table lists the sequences.
