Error Messages
Cisco IOS software displays system error and recovery messages on an external device console terminal
screen. (For more information, see the “Connecting to a Console Terminal or Modem” section on
page 3-22.)
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 A-5 describes system error and recovery messages and LED conditions that might accompany
them.
Note Table A-5 does not provide a complete list of system LED conditions. (For all LED conditions that can
occur in your router, see the “Reading Front-Panel LEDs” section on page A-4 and the “Reading Rear
Panel LEDs” section on page A-6.)
