If Outage Manager is enabled, Outage alarms appear in the UI. Outage alarms are generated when a configured percentage of the children of a component are offline.
- Fiber Node
- Amplifier
- Splitter
- Tap
- Service Location
The parent-to-child relationship is based on where the various components are located in the topology. The children are other topology components on the network that are downstream of the parent. The components are not necessarily devices. The children of a tap are usually service locations. The children of an amplifier can be taps or splitters. The children of a service location are modems.
Each parent component type has one or more thresholds that are configured by your ServAssure NXT administrator. For example, if an outage occurs at a tap and the threshold is set to 75%, then 75% or more of the service locations below the tap are offline. The percentage for your instance of ServAssure NXT is configured by your ServAssure NXT administrator.
The location of the outage propagates up the topology tree. For example, suppose the threshold for service locations is set to 75% and the threshold for taps is set to 100%. If a tap serves 2 service locations, and only one of those service locations is offline, the outage occurs at the service location. However, if both service locations are offline, the outage occurs at the tap.
The following map shows a minor alarm at the amplifier, because more than 75% of the service locations below it are offline.
