Ring Map
Open Status
This field displays the result of the last “open” command or the last attempt by the management station to open onto the ring: whether the management station did in fact open onto the ring, or if an error occurred. This field may display any one of the following:
No Open | An open command has not been issued. |
Bad Param | The open command could not be completed because the |
| parameters did not allow for the station to be opened |
| onto the ring. |
Lobe Test Failed | The lobe media check has failed for the management |
| station. |
Signal Loss | A signal loss condition has been detected at the |
| management station’s receiver input during the open |
| process. |
Insertion Timeout | The management station has failed to logically insert on |
| the ring before the insertion timer expires. |
Purge Failed | The management station has timed out when attempting |
| a ring purge after becoming the active monitor: that is, |
| the management station was unable to receive its own |
| ring purge MAC frames. |
Beaconing | The management station received a beacon MAC frame |
| after physically inserting into the ring. |
Duplicate MAC | Another station on the ring has the same MAC address |
Address | as the management station. |
Parameter Requested | The management station has determined that a Ring |
| Parameter Server (RPS) is present on the ring, but it does |
| not respond to a request initialization MAC frame. |
Remove Received | The management station received a remove adapter |
| MAC frame during the insertion process. |
Open | The open command was completed successfully. |

It is possible for more than one error status to be reported at one time; in this case, the number displayed would be the sum of the codes of the last errors recorded. The following table lists the possible errors and their corresponding error codes:
