3. Enter system view. | system-view | N/A |
4. Enable Boot ROM image validity check. | bootrom-update security-check enable | Optional. By default, the validity check function is enabled. This feature examines the upgrade Boot ROM image for version and hardware incompatibility to ensure a successful upgrade. |
