ATTENTION: If upgrading from a version before v1.8.0, a second reboot is needed to allow the new bootloader to become active.

The EdgeSwitch bootloader controls functions such as the LED boot behavior, configuration/driver loading and much more. The EdgeSwitch bootloader version is not updated automatically with a firmware upgrade and must be updated manually.


Follow the steps below to verify and update the EdgeSwitch bootloader:

CLI: Access the EdgeSwitch Command Line Interface.

1. Enter privileged mode.

enable

2. View the current bootloader version.

show version bootloader
Querying Active and Backup Software, please wait ....
Running Version................................ 0.0.0.0000000
Active Version................................. 1.0.0.4857129
Backup Version................................. 1.0.0.4857129

The EdgeSwitch bootloader uses three different versions:

  • Running Bootloader version that is active.
  • Active Bootloader version that will become active on next boot.
  • Backup Bootloader version stored in memory.

3. Update the bootloader using the command below.

update bootcode active
ATTENTION: This process will take some time to complete. Do not power off or reboot the device during the update process.

4. Reboot the device to apply the new bootloader.
