Using the show environment Command for Basic Troubleshooting
Use the show environment command to
• Make sure the system operating temperature is equal to or less than 40 degrees C or 104 degrees F
at the inlet.
• Report the operational status of the PEMs and blower
If the operating temperature is not between 41 degrees F and 104 degrees F, refer to the “Blower Module
Faults” section on page 2-5.
The following example is sample output from the show environment command:
Router# show environment
Temperature normal:chassis inlet measured at 29C/84F
Temperature normal:chassis core measured at 39C/102F
Fan: OK
Power Entry Module 0 type DC status: OK
Power Entry Module 1 type AC status: Failure
The Cisco 10000 series router default temperature alarm thresholds are programmed to assert at
approximately these conditions:
• Minor inlet and core alarms will assert when the ambient temperature is within a few degrees of 40
degrees C.
• Major inlet and core alarms will assert when the ambient temperature is within a few degrees of 50
degrees C.
• Critical inlet and core alarms will assert when the ambient temperature is within a few degrees of
70 degrees C.
