Start-up Procedures
When the switch starts up following either a power cycle or an operator-
initiated reboot (using the Reset button or RESTART command), a series of
start-up messages is sent to the terminal or PC connected to RS-232 ASYN0
(Figure 2 on page 37).
Figure 2: Switch start-up messages.
After the self tests are complete, the manager is given the option of forcing a
mandatory boot from the EPROM (Flash) release. The message:
Force EPROM download (Y)?
is displayed on the terminal or PC connected to ASYN0 and the switch pauses.
If a key is not pressed within a few seconds, the start-up process will continue
and all steps in the sequence will be executed. Pressing selected keys on the
terminal immediately after the “Force EPROM download” message is
displayed will change the switch start-up process (Table 2 on page 37).
During the start-up process the switch will generate four different types of
messages. All messages are preceded by one of the words INFO, PASS, FAIL,
or ERROR. The significance of these words is shown in Table 3 on page 38.
