lists the DC power thresholds for the normal, warning, and critical (power supply-monitored)
levels.
•
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 will remain disabled until
you toggle the power switch.
Note
A low warning or high warning message does not mean that the router is at risk of malfunctioning or being
damaged.
