What Fault Information Can I See?
9.3.1 How Are Alarms Displayed?
Each node displays an icon, which uses an industry-standard color scheme that indicates the current
alarm status. The multicolor displays are updated in real-time in response to events occurring in the
network. Icons representing network nodes change color dynamically to reflect the status of the node,
which allows rapid recognition of network faults as they occur.
In the Diagnostic Center, Configuration Center, Chassis View, and Statistics Report, you can display the
color legend for alarms, choose Help > Color Legend.
Table 9-2 lists the color legend for alarms.
You can set the Alarm Browser or Alarm Log to display full background color for the entire selected
row. The color corresponds to the alarm status and severity. In the Domain Explorer window, choose
Edit > User Preferences. The User Preferences dialog box appears. On the FM Preferences tab, check
the Color Entire Row in Table View check box.
In the Dashboard, Map Viewer, Alarm Browser, and the Domain Explorer, the color of the border
surrounding a component, or the background color, indicates the operational status of the component.
When status changes, the border or the background color changes as indicated in Table 9-3.

Table 9-3 Dashboard, Map Viewer, Alarm Browser, and Domain Explorer Alarm Severity Color Descriptions
Color Severity Meaning Description
Green Cleared Component is active. The component is operating normally.
Yellow Minor Minor failure. The component is down; both administrative and operational
values are down. This does not necessarily indicate a fault
condition; the component might be disabled.
Orange Major Component is down. Administrative status is up and operational value is down.
Red Critical Component failed. Physical hardware failure.
Cyan (blue-green) Warning Interface is dormant. The interface cannot pass packets, but is in a pending state
waiting for some external event to place it in the up state. The
interface might have packets to transmit before establishing a
connection to a remote system, or a remote system might be
establishing a connection to the interface.
When the pending event occurs, the interface changes to the up
state.
