This allows immediate rollback on system bootup in case the current firmware is corrupt. By default the OLT uses the first firmware (Image 1). You can set the OLT to use another firmware. Use the Boot Image screen to select which firmware you want the OLT to use during system startup. 1 Right-click on an OLT and click Configuration > System Configuration and the Boot Image tab.
