Explanation
Message:
Ring not working
Meaning: The Ring Diagnostic determines that the ring is
beaconing. Recovery can take a some time. If the Ring
Diagnostic was running, auto-recovery is in progress. If
starting the Ring Diagnostic, auto-recovery failed. When Full
E.R. is active and you enter manual recovery, this message
can appear often. This message indicates how the recovery
actions affect the ring. When this message displays, ring status
is Beaconing.
Action: Wait at least one minute and observe ring status.
If ring status does not change, record ring status and do the
following:
1. Disconnect the beaconing adapter from the ring. If this
corrects the problem, run the Adapter Diagnostics on that
PC.
2. Isolate the problem to the PC or the cable, and replace the
damaged element.
3. If the problem persists, it is possible that the MAU has
faults. Break the ring into separate MAUs and
trouble-shoot the problem. Replace the defective MAU
and restore the ring to operation. To properly install the
new MAU (per MAU reset procedure), use the reset tool.
