The system configures itself for unit redundancy:
•
The system determines which unit is the Active unit based on a number of pre-defined criteria. To see which
unit is the active unit, look at the traffic interface LEDs; only the interfaces on the active unit should be
indicated by their LEDs as active and functioning.
•
When the system returns online, all management must be performed via the Active unit using the IP address
you defined for that unit.
•
The IP address you defined for the unit which is now the Standby unit is no longer valid, and the management
port of the Standby unit becomes non-operational. Note, however, that if switchover takes place before you
perform copy-to-mate (Step 5- v), the original IP of the Standby unit, now the Active unit, becomes the
working IP for management of both units.
•
Management of the Standby unit is performed via the Active unit, via the protection cable. Protection
communications are transmitted via Management port 2 in each unit, which is no longer usable or
configurable as a management port.
Note
An PTP 820G unit on which (i) unit redundancy is enabled, (ii) there is no radio link, and (iii) no mate
unit is connected, will automatically be selected as a standby unit when booting up. As a result,
management to the unit will be lost.
In additional, almost every Web EMS page will now include two tabs on top of the main section of the page.
