Description
The Ring Diagnostic processes information, and the ring
operates normally.
The ring experiences intermittent problems. Data
transmitted on the ring more than once are received
correctly.
The ring does not work. A broken wire or a defective
adapter can cause the ring to stop. When the problem is
isolated to one adapter, the system displays the logical
address of the problem to an operator. The system
displays the address of the problem in a data area
message.
