  Functional Overview
Environmental Monitoring and Reporting Functions
Environmental monitoring and reporting functions allow you to maintain normal system operation by 
identifying and resolving adverse conditions prior to loss of operation.
Caution
To prevent overheating the chassis, ensure that your system is drawing cool inlet air. Over temperature 
conditions can occur if the system is drawing in the exhaust air of other equipment. Ensure adequate 
clearance around the sides of the chassis so that cooling air can flow through the chassis interior 
unimpeded and exhaust air exits the chassis and is not drawn into the inlet vent of another device.
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 router is expected to meet the following environmental operating conditions:
  •
Operating Temperature Nominal: 5° to 40°C
  •
Operating Temperature Short Term: 5° to 55°C
  •
Operating Humidity Nominal: 5% to 85% non-condensing
  •
Operating Humidity Short Term: 5% to 90% non-condensing
  •
Operating Altitude: 198 to 13,200 feet (60 to 4000 meters)
  •
DC Input Range: –40.5 to –72 VDC
  •
AC Input Range: 85 to 264 VAC 
If the air temperature exceeds a defined threshold, the system controller displays warning messages on 
the console terminal, and if the temperature exceeds the shutdown threshold, the system controller shuts 
down the system.
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; however, the system is approaching shutdown. Immediate operator action is required.
