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.
•
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.
Fan Failures
When the system power is on, all fans should be operational. The system continues to operate if a fan fails.
When a fan fails, the system displays the following message:
router: 00:03:46:%ENVM-3-BLOWER:Fan 2 may have failed
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.
If the system does shut down because the temperature exceeded the shutdown threshold, the system displays
the following message on the console screen and in the environment display when the system restarts:
Queued messages:
%ENVM-1-SHUTDOWN: Environmental Monitor initiated shutdown
Reporting Functions
The chassis manager on the forwarding engine control processor manages the local resources of the forwarding
processor. It manages the ESI (Enhanced Serdes Interconnect) which are the datapath links on the midplane
connecting the Cisco ASR 1000 Series RP1s, SIPs, and standby ESP modules to the active Cisco ASR 1000
Series Embedded Services Processor. It communicates with the chassis manager on the Cisco ASR 1000
Series Route Processor 1 to report the status and health, including detected hardware failures, ESI status,
software process status, and the state of thermal sensors.
