If you encounter the situation where you have deleted some or all of the files in your switch, 
you may need to load files through the boot line prompt. This load procedure is done before 
the switch has booted. If there is no software available in the switch, then it cannot boot until 
you reload the software.

Using 

ZMODEM

 with the boot prompt is similar to using it with the load command. This 

section covers only specific step-by-step instructions to load a file using 

ZMODEM

 at the 

[boot]: prompt. Before doing this you may want to familiarize yourself with the boot line 
commands. See Appendix A, “Boot Line Prompt,” for more information.

♦ Important Note ♦

Loading software through the boot prompt should only 
be done when the switch is off line and not being used 
for normal network traffic.

1. Connect a terminal to the console port. The terminal must be set to the last values set in 

the switch before it was powered down. For example if you were running at 

19200,8,n,1

, 

you must set your terminal to these values.

If you have deleted or lost your configuration file 
(

), the console port values will revert back to 

the factory settings which are 

9600,8,n,1

.

If you are not sure what baud rate your switch is running, try the last known value. If 
your terminal displays garbage, keep changing the baud rate on your terminal emulator 
until you see normal 

ASCII

 characters.

2. If the switch is on, switch it off for a few seconds, then back on. You should see the boot 

start up on your screen. You will see the following:

The number 2 shown above counts down to 0. To stop the boot, you must press a key 
before the number counts down to 0. If you miss this, simply turn the switch off for a few 
seconds, then back on to restart the process. Note that if there is no software in the switch 
it will not be able to boot and will eventually end up at the [boot] prompt anyway.
