The downloaded image replaces the BootROM in the onboard FLASH memory.

Syntax Description


`ipaddress`	Specifies the IP address of the TFTP server.
`hostname`	Specifies the host name of the TFTP server. Use of the `hostname` option requires that DNS be enabled.

Usage Guidelines

Upgrade the BootROM image only when asked to do so by an Extreme Networks technical representative.

The BootROM image file is designated with a .xtr file extension.

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. You can also download the image to a USB 2.0 storage device.

When you download a BootROM image, you are prompted to install the image immediately after the download is finished. You can also use the install option to choose in advance to install the bootROM image. If you choose to install the image at a later time, use the install bootrom {from-exos} [fname | local-file] {reboot} {slot slotid} command to install the software on the switch.

If this command does not complete successfully it could prevent the switch from booting. If the switch does not boot properly, some boot option functions can be accessed through a special Bootloader menu.

Displaying the BootROM Versions

To display the BootROM version for the switch, use the show version command.

SummitStack Only

You can run this command only from the master node. The file to be downloaded has to be compatible with the type of switch in the specified slot.

If you do not specify a slot number and you elect to install the image after downloading, an attempt is made to install the BootROM image on all active nodes. The BootROM image is not installed on any node if the BootROM image specified is not compatible with all active nodes.
