12 AR Router
C613-03031-01 REV E
After the self tests are complete, the manager is given the option of forcing a
mandatory boot from the EPROM release. The message:
Force EPROM download (Y)?
is displayed on the terminal connected to the console port (port 0) and the
router pauses. If a key is not pressed within a few seconds, the start-up process
continues and all steps in the start-up sequence are executed. Pressing selected
keys on the terminal immediately after the “Force EPROM download” message
is displayed will change the router start-up process (Table 1 on page 12).
During the start-up process the router will generate four different types of
messages. All messages are preceded by one of the words INFO, PASS, FAIL,
or ERROR. The meaning of these words in the context of the messages is
shown in Table 2 on page 12.
The possible messages and their meanings are:
INFO: Self tests beginning.
The code loader tests are about to begin.
INFO: RAM test beginning.
The RAM tests are about to begin.
