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.
