What is the difference between Chassis Down (0x10f69) and Device not responding to polls (0x10009) alarms?

Component: SPCAEM: Events and Alarms

Resolution

“Chassis down” and “Device stopped responding to polls” alarms are effectively the same thing – both mean that the device is unresponsive, and most likely down. We get “Chassis down” alarms on devices where we’ve discovered the physical configuration (chassis and cards), and “Device stopped responding to polls” if we haven’t. If you look at the symptoms of the “Chassis down” alarm, you’ll see that a “Device stopped responding to polls” alarm is also generated, but is being suppressed by the Chassis down alarm.
