To clear a visual alarm, you must resolve the alarm condition. The clear facility-alarm command does not
clear an alarm LED on the Cisco Catalyst 9800-80 Wireless Controller.
Environmental Monitoring
The environmental monitoring functions use sensors to monitor the temperature of the cooling air as it moves
through the chassis.
The local power supplies provide the ability to monitor:
• Input and output voltage
• Output current
• Outlet temperature
The Cisco Catalyst 9800-80 Wireless Controllers are expected to meet the following environmental operating
conditions:
• Operating Temperature Nominal: 32° to 104° F (0° to 40°C)
• Operating Temperature Short Term: 32° to 131° F (0° to 50°C)
• Operating Humidity Nominal (relative humidity): 10 to 90% relative
• Operating Humidity Short Term: 5 to 90% relative
• Operating Altitude: –500 to 10,000 feet (–152.4 to 3048 meters)
• DC Input Range: –50 to –72 VDC
• AC Input Range: 85 to 264 VAC
In addition, the power supplies monitor internal power supply temperatures and voltages. A power supply is
either within tolerance (normal) or out of tolerance (critical). If an internal power supply temperature or voltage
reaches a critical level, the power supply shuts down without any interaction with the system processor.
The environmental monitoring functions use the following levels of status conditions to monitor the system:
• Normal—All monitored parameters are within normal tolerances.
• Warning—The system has exceeded a specified threshold. The system continues to operate, but operator
action is recommended to bring the system back to a normal state.
• Critical—An out-of-tolerance temperature or voltage condition exists. The system continues to operate,
but the system is approaching shutdown. Immediate operator action is required.
• Shutdown—Before any shutdown, the system logs the status of monitored parameters in NVRAM so
that you can retrieve it later to help determine the cause of the problem.
• Power supply shutdown—The power supply detected an internal out-of-tolerance overvoltage,
overcurrent, or temperature condition and shut itself down. All DC power remains disabled until you
toggle the chassis power switch.
