Upgrading and Accessing BootROM
ExtremeWare 7.2e Installation and User Guide 319
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 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.
