These queries are a powerful grid diagnostic tool, enabling you to
identify alarm patterns and service issues. Regularly reviewing alarm
patterns can resolve minor issues before they impact grid functionality.
At the very least, reviewing the alarm history gives an overview of
how the system is functioning and may help to prevent future alarms.
Alarm Handling
The NMS is a critical tool for responding to system alarms. When you
receive an alarm notification, the NMS provides the data necessary to
resolve the issue. This section provides step-by-step procedures for
investigating, evaluating, and responding to alarms.
Tracing the Source of an Alarm
Tracing an alarm follows these main steps (each is expanded later in
the text):
1. Trace through the network tree to the specific node generating the
alarm.
2. Use the information from the Alarms table to identify the compo-
nent and attribute causing the alarm.
3. Troubleshoot the alarm by using the lookup table in Chapter 7,
“Troubleshooting Alarms” on page 171.
1. Locate the Source of an Alarm
a. Log in to the NMS to display the Network Map. Use the icons
and color codes (Table 3 on page 29) to determine which
location has triggered the alarm.
b. Select the Site that is displaying the alarm icon to view the
cabinet icons for that location. Use the icons and color codes to
determine which cabinet has triggered the alarm.
c. Select the cabinet that is displaying the alarm icon to view the
node icons for that cabinet.
d. Select the node with the alarm icon to view the service icons
for that node. Use the color codes to determine which service
has triggered the alarm.
e. Select the service with the alarm color to access the service’s
Overview page.

X Main page to view the summary table of
monitored attributes for the service and its components. Locate
