Accessing the BootROM menu
Interaction with the BootROM menu is only required under special circumstances, and should be done
only under the direction of Extreme Networks Customer Support. The necessity of using these functions
implies a non-standard problem which requires the assistance of Extreme Networks Customer Support.
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
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.
