Checking standby carriers
Preparation:
n The respective DIB-R5 advanced must be in operation.
n The NMC-511 FaultManager must have been started.
1. Select the corresponding operational carrier in the Equipment or Visualization view
of the NMC-511 FaultManager.
2. Right-click on the selected carriers to display the context menu.
ð
The context menu will be displayed.
Availability of maintenance functions
Not all the maintenance functions can be used for all the network constituents.
Maintenance functions that cannot be performed for the time being will be dis-
played in grey and cannot be selected.
3. In the context menu, click on the System blocking maintenance function.
ð
The corresponding carriers are excluded from functional operation and identi-
fied in the Equipment view with the "Person" icon (operationally blocked by the
user).
Existing standby carriers are enabled.
4. In the NMC-511 FaultManager, check in the Equipment view of the Equipment
perspective whether the standby carriers become active and do not report alarm.
5. Unblock any blocked operational carriers after at least 5 minutes with the System
release maintenance function.
ð
The system blocking of operational carriers has been revoked.
Standby carriers are switched back to their original status.
