Usage Guidelines
Upgrade the BootROM image only when asked to do so by an Extreme Networks technical representative.
Prior to downloading the BootROM image on the switch, you must download the image you received from Extreme Networks to a TFTP server on your network. If present on your switch, you can also download the image to a compact flash card or USB 2.0 storage device.
Specify the ipaddress or hostname parameters to download a BootROM image from a TFTP server on the network.
The BootROM image file is a .xbr file, and this file contains the executable code.
If this command does not complete successfully it could prevent the switch from booting. In the event the switch does not boot properly, some boot option functions can be accessed through a special Bootloader menu.
Use of the hostname parameter requires that DNS be enabled.
Displaying the BootROM Versions
To display the BootROM version for the switch, use the show version command.

You can issue this command only from the Master node. When provided, the file to be downloaded has to be compatible with the type of Summit in the specified slot if the user confirms that the image is to be installed.
If no slot number is provided and the user confirms installation in the case of download, an attempt is made to install the bootrom image on all active nodes. The bootrom image will not be installed on any node if the bootrom image specified is not compatible with all active nodes.
Example
The following example downloads a bootROM image from the tftp server tftphost from the file bootimage:
download bootrom tftphost bootimage
