Alarms
This section describes alarms, which indicate problems on the Cisco ICS 7750 or
on systems with which it is communicating.
Alarms are associated with the following:
• Events—Physical problems, such as system overheating or loss of power,
detected by the SAP card and reported to the ICS System Manager software.
Events are associated with the following system components:
–
Chassis/backplane
–
Fans
–
Power supply modules
• Traps—Problems, such as a trunk outage, that are detected by MRP cards and
transmitted in the form of a Simple Network Management Protocol (SNMP)
message.
Note For more information about SNMP messages, see “SNMP Basics” on
page 2-10. To find out how to identify and solve system problems, see
Chapter 4, “System Troubleshooting Guidelines,” and Appendix A, “Error
Message Summary.”
Alarm Notification
The system issues notifications of alarms in any of the following ways:
• ICS System Manager is notified of an event and takes the appropriate action;
for example, it changes the state of one or more LEDs on the system and
generates an error message, which you then see.
• An SNMP agent generates a trap that is collected by ICS ICS System
Manager or another SNMP management application, which processes the
trap and takes the appropriate action.
• You have an open communications session with the Cisco ICS 7750 and
retrieve log messages associated with any alarms.
