System Messages
The terminal should display one of the following prompts:
Router> (indicates the user EXEC command mode)
or
Router# (indicates the privileged EXEC command mode)
The Cisco IOS software checks the system condition once every 30 seconds. If the condition still exists,
the error message appears again; if the error condition has cleared, a recovery message appears.
Table 3 describes system error and recovery messages and LED conditions that might accompany them.
Note Table 3 does not provide a complete list of system LED conditions. (For all LED conditions that can
occur in your router, see the “Reading System LEDs” section on page4 and the “Reading Port and
Module LEDs” section on page 6.)

Amber Error:
%SYS-1-OVERTEMP: System detected OVERTEMPERATURE condition. Please resolve cooling
problem immediately!
Explanation:
The router is operating at an abnormally high temperature, possibly caused by one or more of
the following conditions:
•Fan failure
•Air conditioner failure in the room
•Air blockage to cooling vents
Recovery:
Make sure that the room temperature is not too high and that airflow to the router is not blocked.
See also the “Site Environment” section on page4 and the “Equipment Racks” section on
page 5.
If this condition persists, the environmental monitor might shut down the system. Call your
Cisco technical support representative for assistance, if necessary.
When the error condition is resolved, the SYS PWR LED changes to green, and the following
informational message appears:
%ENVMON-3-OVERTEMP_OK: System temperature normal
Note These messages are not supported on the Cisco 2801.
