Chapter 2 Alarm Troubleshooting
The Open Shortest Path First (OSPF) Hello alarm is raised when the two end nodes cannot bring an
OSPF neighbor up to the full state. Typically, this problem is caused by an area ID mismatch, and/or an
OSPF HELLO packet loss over the DCC.
Clear the HELLO Alarm
Ensure that the area ID is correct on the missing neighbor:

2.7.158 HIBATVG
The High Voltage Battery alarm occurs in a –48 VDC environment when a battery lead input voltage
exceeds the high power threshold. This threshold, with a default value of –52 VDC, is
user-provisionable. The alarm remains raised until the voltage remains under the threshold for
120 seconds. (For information about changing this threshold, refer to the "Turn Up Node" chapter in the
Cisco ONS 15454 Procedure Guide.
Clear the HIBATVG Alarm
The problem is external to the ONS 15454. Troubleshoot the power source supplying the battery leads.
