- PROBLEM: Token-Ring Error: "Token ring status beaconing. Status=520
- (also 420)." "Alert condition has been corrected." This
- appears on the file server.
-
- SOLUTION: When a workstation has not received the token after a
- certain period of time from his upstream neighbor, the
- workstation sends a "beacon packet" to the active monitor on
- the ring. The active monitor then checks to see which
- workstation is not responding and disconnects the guilty
- party. That is when the second message appears.
-
- Find the bad link--whether it is a card, cable, MAU port,
- etc.
