Error Messages

This section describes error messages that may appear on an external console screen. (For more information about consoles, see the “Connecting a Console or Modem” section on page 29 of “Connecting Cables to Cisco 3800 Series Routers.”)

Cisco IOS software checks the system once every 30 seconds. If an error still exists, the error message is displayed again; if the error has cleared, a recovery message is displayed.

Error Message System detected OVERTEMPERATURE condition. Please resolve cooling problem immediately!

Explanation The router is operating at a temperature higher than the user-set threshold, possibly caused by fan failure, air-conditioning failure in the room, or air blockage to cooling vents.

Recommended Action Make sure that the ambient room temperature does not exceed 40 degrees C and that airflow to the router is not blocked. See the “Site Environment” section on page 4 and the “Equipment Racks” section on page 5 of “Preinstallation Requirements and Planning for

Cisco 3800 Series Routers.”

If this condition persists, the power-supply thermal monitor automatically shuts down the router. Call your Cisco technical support representative for help, if necessary.
