2.2 Cease the License Management, Emergency Unlock Reset Key Required Alarm

Steps

Contact your Ericsson supplier to order an Emergency Unlock Reset Key and have it provisioned in NeLS. For more information on provisioning licenses in NeLS, refer to the documentation that comes with your version of the product software.

Result:

After the emergencyResetKey has been successfully provisioned, EmergencyUnlock.activationsLeft is automatically reset.

Note:

LM must have NeLS access to reset EmergencyUnlock.activationsLeft.

Use ssh to connect to the COM CLI Management System server port on the blade where the active COM CLI is running:

ssh <username>@<blade_IP_address> -p 22 -t -s cli

Note: The default COM CLI Management System server port is 22.
Check the value of EmergencyUnlock.activationsLeft:

show ManagedElement=1,SystemFunctions=1,Lm=1,EmergencyUnlock=1, activationsLeft

The system returns activationsLeft=2 if the counter has been reset.
Check the alarm status.

If the alarm is still active, consult the next level of maintenance support. Further actions are outside the scope of this instruction.
