Figure 130: Example of a submap node with alarm status
The submap node icon shows the following information:
The name of the node (submap), which can be edited. By default, it is given the subnet address/
●
subnet mask as the name.
The submap alarm status, indicated by the presence of an alarm icon (small bell). The alarm status
●
shows the highest level alarm currently unacknowledged for any device within the submap. If
multiple devices within the submap have unacknowledged alarms, the icon indicates the most
severe alarm among all those devices. The color of the bell indicates the severity of the alarm.
If the alarm icon has an "X" through it, this means alarm propagation has been disabled for this
submap; the alarm status of this submap does not influence the aggregate alarm status displayed for
higher level maps.
A submap node does not provide any additional status information.
Hyper Nodes. A hyper node represents a link termination where the terminating node is present on
another map. A hyper node shows the same information as the node it represents (except for the
optional node annotation). A hyper node can have links only between itself and other devices on the
displayed map. A hyper node does not link to other hyper nodes.
You can double-click on a hyper node icon to navigate directly to the map and the device represented
by the hyper node.
Figure 131: Example of a hyper node icon representing a device
A hyper node icon shows the following information:
The name of the device node that this hyper node represents (this can be hidden using View or Map
●
properties).
An optional, user-supplied annotation for a device hyper node. This is a different annotation than
●
will appear in the device node that this hyper node represents.
The device IP address, for a device hyper node.
●
The device status, for a device hyper node, as indicated by the color of the icon border:
●
A green border indicates that the device is up.
■
A red border indicates that the device is down.
■
A gray border indicates that the device has been taken offline.
■
The device alarm status, indicated by the presence of an alarm icon (small bell). The alarm status
●
shows the highest level alarm currently unacknowledged for the device. The color of the bell
indicates the severity of the alarm.
If no icon appears, then either there are no unacknowledged alarms for the device, or the alarm
status is below the alarm status threshold for the view.
