Troubleshooting
Events and Alarms  
Both events and alarms are stored within circular memory buffers. When the buffers become full, older events and 
alarms are overwritten by newer entries. Both events and alarms are stored in shared RAM. However, the 40 most 
recent alarms are also stored in flash RAM. Storing these 40 alarms in flash RAM makes them persistent between 
reboots of the ATM SmartSwitch, and provides information about the state of the switch prior to reboot.
Note
Alarms are collected and stored in flash RAM in groups of four. As a result, some 
of the most recent alarms may not be persistent. For example, there are 24 (6 times 
4) alarms stored in flash RAM. If a 25th alarm occurs, and the switch is rebooted, 
only the 24 alarms are persistent. The 25th alarm is dropped because the number 
of alarms (after 24) did not reached the next multiple of four (28).
