About Environmental Monitoring
Conditions on Supervisor Engine 6-E and Supervisor Engine 6L-E
Supervisor Engine 6-E, Supervisor Engine 6L-E, and its associated line cards support multiple
temperature sensors per card. The environment condition output includes the temperature reading from
each sensor and the temperature thresholds for each sensor. These line cards support three thresholds:
warning, critical, and shutdown. (Supervisor Engines II-Plus to V-10GE support two threshold.)
The following example illustrates how to display the environment condition on a
Supervisor Engine 6-E and Supervisor 6L-E. The thresholds appear within parentheses.

Emergency Actions
Chassis with Supervisor Engine 6-E and Supervisor 6L-E can power down a single card, providing a
detailed response to over-temperature conditions on line cards. However, Supervisor Engine 6-E and
Supervisor 6L-E cannot safely operate when the temperature of the supervisor itself exceeds the critical
threshold. The supervisor engine 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. Table 10-2 lists temperature
emergencies but does not distinguish between critical and shutdown emergencies.
