Accessing the Bootstrap CLI on the Summit X450
The bootstrap CLI contains command to support the selection of which bootloader to use.
To access the bootstrap CLI, follow these steps:
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.
For detailed information and instructions on accessing the bootloader, see “Accessing the Bootloader”
on page 605 .
Upgrading the Firmware—BlackDiamond 8800 Family
of Switches Only
Firmware images are bundled with ExtremeWare XOS software images. ExtremeWare XOS
automatically compares the existing firmware image flashed into the hardware with the firmware image
bundled with the ExtremeWare XOS image when you:
●
Download a new version of ExtremeWare XOS to the active partition.
●
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 switch’s
behavior during a firmware upgrade, use the following command:
configure firmware [auto-install | install-on-demand]
Where the following is true:
●
auto-install
—Specifies ExtremeWare XOS 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.
●
on-demand
—Specifies the switch to prompt you to upgrade the firmware when ExtremeWare XOS
determines that a newer firmware image is available. This is the default behavior.
Use the
install firmware {force}
command to install the firmware bundled with the ExtremeWare
XOS image on the BlackDiamond 8800 family of switches. Specify the
force
parameter only under
guidance from Extreme Networks Technical Support personnel. Forcing a firmware upgrade may cause
incompatibility issues between the firmware and the software installed on the MSM.
During the firmware upgrade, do not cycle down or disrupt the power to the switch. If a power
interruption occurs, the firmware may be corrupted and need to be recovered. ExtremeWare XOS
automatically attempts to recover corrupted firmware; however, in some situations user intervention is
required.
