Chapter 2 Messages and Recovery Procedures ENVIRONMENT Messages ENVIRONMENT Messages Error Message ENVIRONMENT-3-OVERTEMP: Internal Temperature crossed over Max Temperature Threshold Explanation The switch internal temperature is higher than the maximum temperature threshold. Recommended Action This could be a hardware failure. If a power-supply or fan module failed, replace it. Check that the ambient temperature is not too high. Use the show environment temperature status privileged EXEC command to display the temperature sensor values and the temperature thresholds. Check that proper air flow is maintained. If the message appears again, contact TAC or your Cisco representative to have the switch replaced. Error Message ENVIRONMENT-3-UNDERTEMP: Internal Temperature crossed under Min Temperature Threshold Explanation The switch internal temperature is lower than the minimum temperature threshold. Recommended Action Check that the ambient temperature is not too low. Use the show environment temperature status privileged EXEC command to display the temperature sensor values and the temperature thresholds. If the message appears again, contact TAC or your Cisco representative to have the switch replaced. Error Message ENVIRONMENT-4-SECONDARY_UNDERTEMP: Internal Temperature returns to Safe Temperature Range from Cold Condition Explanation The switch internal temperature was lower than the configured minimum threshold but is now within the normal range. Recommended Action No action is required. Error Message ENVIRONMENT-3-OVERVOLT: [chars] Line Exceeds High Threshold Limit Current Voltage (mV): [dec] Explanation The voltage rail is higher than the maximum voltage threshold. [chars] is the voltage rail, and [dec] is the voltage. Recommended Action If the message appears again, contact TAC or your Cisco representative to have the switch replaced. Error Message ENVIRONMENT-3-UNDERVOLT: [chars] Line Exceeds Low Threshold Limit Current Voltage (mV): [dec] Explanation The voltage rail is lower than the minimum voltage threshold. [chars] is the voltage rail, and [dec] is the voltage. Recommended Action If the message appears again, contact TAC or your Cisco representative to have the switch replaced.

ENVIRONMENT Messages
Error Message
ENVIRONMENT-3-OVERTEMP: Internal Temperature crossed over Max
Temperature Threshold
Explanation
The switch internal temperature is higher than the maximum temperature threshold.
Recommended Action
This could be a hardware failure. If a power-supply or fan module failed,
replace it. Check that the ambient temperature is not too high. Use the
show environment
temperature status
privileged EXEC command to display the temperature sensor values and the
temperature thresholds. Check that proper air flow is maintained. If the message appears again,
contact TAC or your Cisco representative to have the switch replaced.
Error Message
ENVIRONMENT-3-UNDERTEMP: Internal Temperature crossed under Min
Temperature Threshold
Explanation
The switch internal temperature is lower than the minimum temperature threshold.
Recommended Action
Check that the ambient temperature is not too low. Use the
show environment
temperature status
privileged EXEC command to display the temperature sensor values and the
temperature thresholds. If the message appears again, contact TAC or your Cisco representative to
have the switch replaced.
Error Message
ENVIRONMENT-4-SECONDARY_UNDERTEMP: Internal Temperature returns to
Safe Temperature Range from Cold Condition
Explanation
The switch internal temperature was lower than the configured minimum threshold but
is now within the normal range.
Recommended Action
No action is required.
Error Message
ENVIRONMENT-3-OVERVOLT: [chars] Line Exceeds High Threshold Limit
Current Voltage (mV): [dec]
Explanation
The voltage rail is higher than the maximum voltage threshold. [chars] is the voltage
rail, and [dec] is the voltage.
Recommended Action
If the message appears again, contact TAC or your Cisco representative to have
the switch replaced.
Error Message
ENVIRONMENT-3-UNDERVOLT: [chars] Line Exceeds Low Threshold Limit
Current Voltage (mV): [dec]
Explanation
The voltage rail is lower than the minimum voltage threshold. [chars] is the voltage rail,
and [dec] is the voltage.
Recommended Action
If the message appears again, contact TAC or your Cisco representative to have
the switch replaced.
