As soon as you see the
BootROM->
prompt, release the spacebar. You can see a
simple help menu by pressing
h
. Options in the menu include
Selecting the image to boot from
Booting to factory default configuration
Performing a serial download of an image
For example, to change the image that the switch boots from in flash memory, press
1
for the image stored in primary or
2
for the image stored in secondary. Then, press the
f
key to boot from newly selected on-board flash memory.
To boot to factory default configuration, press the
d
key for default and the
f
key to
boot from the configured on-board flash.
To perform a serial download, you can optionally change the baud rate to 38.4K using
the
b
command, and then pressing the
s
key to prepare the switch for an image to be
sent from your terminal using the XMODEM protocol. After this has completed, select
the
g
command, to boot the image that is currently in RAM. The switch restores the
console port to 9600 bps, and begins the boot process.
Doing a serial download does not store an image into flash, it only allows the
switch to boot an operational image so that a normal TFTP upgrade from CLI
can then be performed.
