ExtremeWare 7.2e Installation and User Guide
323
To access the BootROM menu, follow these steps:
1
Attach a serial cable to the console port of the switch.
2
Attach the other end of the serial cable to a properly configured terminal or terminal emulator,
power cycle the switch while depressing the spacebar on the keyboard of the terminal.
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 115200 using the
b
command.
Then press the
s
key to prepare the switch for an image to be sent from your terminal using the
1K XMODEM protocol. (You can use a Windows Hyperterminal program to accomplish this step.) After
the transfer is complete, the switch restores the console port to 9600 bps and begins the boot process.
