Chapter 6 Maintenance
Environmental Monitoring and Reporting Functions
You can remove and replace a port adapter with the same type of component without interrupting the system. To replace a port adapter with a different type of port adapter (for example, replacing a HSSI adapter with an ATM adapter), you must to copy your startup configuration to your running configuration on the Cisco uBR7100 series router to enable the interfaces on the port adapter.
Environmental Monitoring and Reporting Functions
Environmental monitoring and reporting functions are controlled by the network processor and allow you to maintain normal system operation by identifying and resolving adverse conditions that might disrupt operation.
The environmental monitoring functions constantly monitor the internal chassis air temperature and power supply voltages and currents. The power supply monitors its own voltage and temperature and shuts itself down if it detects a critical condition within the power supply. The reporting functions periodically log the values of measured parameters so that you can retrieve them for analysis later, and the reporting functions display warnings on the console if any of the monitored parameters exceed defined thresholds.
The front and back of the chassis must remain unobstructed to ensure adequate airflow and prevent overheating inside the chassis; we recommend at least 3 inches (7.6 cm) of clearance. Temperature sensors in the router monitor the internal air temperature and send warning messages when the internal air temperature exceeds the specified threshold.
Environmental Monitoring
The environmental monitoring functions use four sensors to monitor the temperature of the cooling air as it moves through the chassis.
If the air temperature exceeds a defined threshold, the router displays warning messages on the console terminal. The system stores the present parameter measurements for both temperature and power voltage in NVRAM so you can retrieve them later.
In addition, the power supply monitors the internal power supply temperature and voltages. A power supply is either within tolerance (normal) or out of tolerance (critical). If the 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:
