Emergency Actions
The chassis can power down a single card, providing a detailed response to over-temperature conditions on
line cards. However, the chassis cannot safely operate when the temperature of the supervisor module itself
exceeds the critical threshold. The supervisor module turns off the chassis' power supplies to protect itself
from overheating. When this happens, you can recover the switch only by cycling the power on and off
switches on the power supplies or by cycling the AC or DC inputs to the power supplies.
Critical and shutdown temperature emergencies trigger the same action. The following table lists
temperatureemergencies but does not distinguish between critical and shutdown emergencies.
Table 20: Emergency and Action
Case 1. Complete fan failure emergency.
Case 2. Temperature emergency on a line card.
Case 3. Temperature emergency on a power supply.
When critical or shutdown alarm threshold is
exceeded, all the power supplies will shut down.
