Environmental Monitoring and Reporting Functions
Environmental monitoring and reporting functions are controlled by the network
processing engine or network services engine and allow you to maintain normal
system operation by identifying and resolving adverse conditions prior to loss of
operation. The environmental monitoring functions constantly monitor the
internal chassis air temperature and DC supply voltages and currents. Each power
supply monitors its own voltage and temperature and shuts itself down if it detects
a critical condition within the power supply. If conditions reach shutdown, the
system shuts down to avoid equipment damage from excessive heat. 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.
Environmental Monitoring
The environmental monitoring functions use four sensors, two on the network
processing engine or network services engine and two on the I/O controller, to
monitor the temperature of the cooling air as it moves through the chassis.
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. The system
stores the present parameter measurements for both temperature and DC voltage
in NVRAM so you can retrieve them later as a report of the last shutdown
parameters.
In addition, the power supplies monitor internal power supply temperature 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.
Cisco 7200 VXR Installation and Configuration Guide
1-64
Brings all previously configured interfaces on the port adapter back to the
state they were in when they were removed. Any newly inserted interfaces are
put in the administratively shutdown state, as if they were present (but not
configured) at boot time. If a similar port adapter type is reinserted into a slot,
its ports are configured and brought online up to the port count of the original
port adapter. (A service adapter has no configurable ports.)
