Upgrading the Firmware (ExtremeSwitching X440-G2 and X620 Series
Switches Only)
Firmware images are bundled with ExtremeXOS software images. The bundled
firmware images include system FPGA and PLD images. When you download and install a new
version of ExtremeXOS, ExtremeXOS automatically compares the existing firmware image against
the firmware images bundled with the ExtremeXOS image.
After a firmware image upgrade, messages are sent to the log.
- To install the firmware bundled with the ExtremeXOS image,
use the install firmware {force}
{slot
slot-number} command.
If the bundled firmware image is newer than the existing firmware
image, the switch prompts you to confirm the upgrade.
- At the prompt:
- Type y to upgrade the
firmware.
- Type n to cancel the firmware upgrade for the specified
hardware, and continue scanning for other hardware that needs to be upgraded.
- Press Enter to cancel the upgrade.
During the firmware upgrade, the
switch also prompts you to save your configuration changes to the current, active
configuration.
- To save your configuration changes to the current, active
configuration, type y or to
discard your changes, type n.
The new firmware overwrites the older
version.
You must reboot the switch to load the newly
installed firmware. However, you do not need to do this immediately after a firmware upgrade.
Use the
reboot command to reboot the switch and
activate the new firmware. During the firmware upgrade, do not turn off or disrupt the power
to the switch. If power is lost, the firmware may be corrupted and need to be recovered.
ExtremeXOS automatically attempts to recover corrupted firmware; however, in some situations
user intervention is required.
