Upgrading the BootROM

ExtremeXOS Concepts Guide, Software Version 12.4 1395

Upgrading the BootROM

BlackDiamond 10808 Switches Only

Upgrade the BootROM from a TFTP server on the network or an external compact flash memory card installed in the compact flash slot of the MSM, after the switch has booted. For information about loading an image to a TFTP server and verifying which virtual router connects to your TFTP server, see Installing a Core Image on page 1372. Upgrade the BootROM only when asked to do so by an Extreme Networks technical representative. To upgrade the BootROM, use the following command: download bootrom [[ | ] {{vr} } | memorycard

] {msm }

Summit Family Switches and SummitStack Only

The Summit family switches have a two-stage BootROM. The first stage, called bootstrap, does basic initialization of the switch processor and will load one of two second-stage bootloaders (called primary and secondary).If the switch does not boot properly, both the bootstrap and the bootloader allows the user to access the boot options using the CLI.If necessary, the bootloader can be updated after the switch has booted, using TFTP. You can upgrade the BootROM from a TFTP server on the network after the switch has booted and only when asked to do so by an Extreme Networks technical representative. For information about loading an image to a TFTP server and verifying which virtual router connects to your TFTP server, see Installing a Core Image on page 1372.To upgrade the BootROM, use the following command: download bootrom [ | ] {{vr} }

On a SummitStack, the BootROM can be centrally upgraded. Use the command above on the primary (Master) stack node to download a BootROM to all stacking nodes. To download to a single stacking node, you need to specify the slot parameter:download bootrom [ | ] {slot } {{vr}

}

NOTE

User-created VRs are supported only on the platforms listed for this feature in Appendix A, ExtremeXOS Software

Licenses.

Accessing the Bootstrap CLI on the Summit Family Switches

The bootstrap CLI contains commands to support the selection of which bootloader to use. Interaction with the bootstrap is required only under special circumstances and should be done only under the direction of Extreme Networks Customer Support. To access the bootstrap CLI:

Software Upgrade and Boot Options

ExtremeXOS Concepts Guide, Software Version 12.41396

1 Attach a serial cable to the serial console port of the switch.2 Attach the other end of the serial cable to a properly configured terminal or terminal emulator.3 Power cycle or reboot the switch.4 As soon as you see the Bootstrap Banner, press the spacebar.

The BOOTSTRAP> prompt appears on the screen.

NOTE

If you accidentally enter the bootstrap CLI when you want to enter the Bootloader, at the BOOTSTRAP> prompt enter the boot command.

For detailed information and instructions on accessing the bootloader, see Accessing the Bootloader on page 1393.

Upgrading the Firmware

BlackDiamond 8800 Series Switches Only

Firmware images are bundled with ExtremeXOS software images. The firmware contains BootROM images for the MSM and I/O modules and associated firmware images for the backplane and PSU controllers. ExtremeXOS automatically compares the existing firmware image flashed into the hardware with the firmware image bundled with the ExtremeXOS image when you:l Download a new version of ExtremeXOS to the active partition.l Install a new module into an active chassis.After a firmware image upgrade, messages are sent to the log. You can configure the switch to automatically upgrade the firmware when a different image is detected, or you can have the switch prompt you to confirm the upgrade process. To configure the switchs behavior during a firmware upgrade, use the following command:configure firmware [auto-install | install-on-demand]

Where the following is true:l auto-installSpecifies ExtremeXOS to automatically upgrade the firmware if the software detects

a newer firmware image is available. The switch does not prompt you to confirm the firmware upgrade.

l on-demandSpecifies the switch to prompt you to upgrade the firmware when ExtremeXOS determines that a newer firmware image is available. This is the default behavior.

You can use the install firmware {force} command to install the firmware bundled with the ExtremeXOS image. To install the new BootROM and firmware, wait until the show slot command indicates the MSM and I/O modules are operational. When the modules are operational, use the install firmware command. If the bundled firmware image is newer than the existing firmware image, the switch prompts you to confirm the upgrade. l Enter y to upgrade the firmware.
