Chapter 1 Cisco 7200 VXR Product Overview
Functional Overview
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.
• Shutdown—The processor has detected a temperature condition that could
result in physical damage to system components and has disabled DC power
to all internal components. This condition requires immediate operator
action. All DC power remains disabled until you toggle the power switch.
Before any shutdown, the system logs the status of monitored parameters in
NVRAM so 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 power
switch.
Table 1-22 lists the typical temperature thresholds for each network processing
engine type, and Table 1-23 lists the DC power thresholds for the normal,
warning, and critical (power supply-monitored) levels.
