When the system issues a major alarm, it starts a timer whose duration depends on the alarm. If the alarm
is not canceled before the timer expires, the system takes emergency action to protect itself from the
effects of overheating. The timer values and the emergency actions depend on the type of supervisor
engine.
Note Refer to the Catalyst 4500 Series Switch Module Installation Guide for information on LEDs, including
the startup behavior of the supervisor engine system LED.
Table 10-4 describes the alarms on Supervisor Engines II-Plus to V-10GE.
