IMG 1010 - Alarms

Below are just a few alarms and how they are displayed.

Span Alarms

Carrier Group Alarm (CGA) or Span Dead

Description:

The IMG will send a number of different alarms to EventView depending on what event has occurred to that span. Below is screen capture of what EventView will display if the cable is removed from one of the bearer spans.

Cable removed from interface 4 which has a bearer span configured on it

Open

Possible Problem:

This alarm is generated when the IMG detects a carrier group alarm for more than the configured time period. Possible problems:

• A clock source was lost.

• A T1/E1 cable was removed or went bad. A physical connection to the TDM (Time Division Multiplexed) network went bad.

• Is span configured correctly and are both local and remote ends configured the same.

Fix:

Repair or replace the bad cable

Data:

The data displayed in Eventview is shown in screen capture above

License Failure Alarms

License Logical Node ID Mismatch Alarm

Description:

The following alarm is generated when the Logical Node ID of an IMG and the Logical Node ID specified in the .csa file being loaded for that same IMG are not the same value.

Problem:

The alarm will display in Eventview if the following is true:

The Logical Node ID being reported by an IMG in the Poll (0x0170) message is not the same value as specified in the .csa file being loaded from ClientView for that same IMG and the Logical Node ID being reported is not 255.
All newly reset IMG’s report a Logical IMG of 255 to indicate that the Logical Node ID needs to be set.

Fix:

Reset the IMG. Upon completion of the reset, the IMG should configure normally.

Data:

"HostAlarm(Node=0, Type=Communications, SubType=Node Detected LNI Reset. Manual Reset Required., Severity=Major)"
