Fault data is available for managed chassis, module, and interface objects regarding the overall management connectivity and environmental aspects. Fault management functionality is supplemental to the processing of alarm notifications from the Cisco Access Router Manager router. Some data the fault management windows provide lead to alarms, while other data is purely statistical and may not require further action. For information on the alarms supported, see "Alarms".
Not all the data which the fault management windows provide produce alarms. Alarms occur when specific system occurrences coincide with the definitions of SNMP traps. If the set trap data is met, Cisco EMF translates the trap data into an alarm. For further information on traps and alarms, see the "Alarms".
Fault information for both chassis and module objects provides availability data, including up time, the most recent object change and restart. In addition, module fault data indicates the operational status and the amount of free memory. Chassis fault data extends to environmental fault management information. Environmental fault management data displays in the form of four tables that report on the status of power supplies, voltage, temperature and fans within the chassis. Each table contains a column that indicates the current state of each testpoint. This can be either Normal, Warning, Critical, Shutdown or Not Present.
Interface fault management is only applicable to ATM interfaces. The data which displays consists of statistical count of errors the interface encounters, including total number of errors, transmit errors, SONET errors, and DS1/E1/DS3/E3 errors. Additional status information is available for managed interfaces on the device. Using the status indicators the corresponding windows provides, it is possible to determine if particular objects require attention
The Fault Management chapter covers the following:
The Chassis Fault Management window is a read-only window that provides fault information for a selected chassis.
To view the Chassis Fault Management window, proceed as follows:
Step 1 Right-click (on a relevant object icon in the Map Viewer window or from an object pick list) and choose Cisco Access Router Manager > Fault > (Chassis >) Fault Management. For information on which objects allow you to launch the Chassis Fault Management window, see "EM Windows".

SONET Interface Status
The presentation of SONET interface status information provides easy to decipher color indicators for several of the values. Possible color indicators which may display are green (OK, no errors), red (errors), or yellow (suppressed errors).
Error suppression occurs when an error in one field prevents data retrieval for another field. The following table lists the SONET status attribute suppression behavior rules for what happens when certain conditions arise. Examples of how to read the table and how the data the table displays related to the status color indicators on the Section, Line, Path, and Virtual Tributary tabs of the SONET Interface Status window follow.

"S" indicates that the attribute value is suppressed and the color indicator will be yellow, and "—" indicates that the attribute value is not suppressed.
For example, the Rule 1 column indicates that if item (4), Alarm Indication Signal, is asserted, that is, the color indicator is red, then items (5), (7), (8), (9), (10), and (11) are suppressed, that is, the color indicator is yellow. The fields are yellow because the data cannot be retrieved due to the indication of a failure by the field that is red.
