• In idle mode the role of Chassis Supervision is limited to monitoring the temperature, power supply,
fan(s), handling of flash synchronization and takeover. The following services are provided when
running in idle mode:
• Prober needs to monitor the temperature and report a temperature rising over a defined warning thresh-
old to HSM.
• When HSM receives a message from prober indicating that the temperature has risen over the defined
shutoff threshold, it must send a trap and shutdown the local unit.
• CVM must listen to flash synchronization coming from CVM on the primary.
• Chassis Supervision does not implement the Hello Protocol as defined in Falcon/Eagle. It receives noti-
fication from Stack Manager to change to a new mode. The following figure illustrates the different
possible transitions.
• When running in idle mode and upon reception of a notification of Stack Manager indicating the new
state, Chassis Supervision shutdowns the daughter tasks and spawns them according to the new mode.
