How to Soft Power cycle the router to install the BOOT FPGA firmware
The following article explains the method to upgrade the BOOT FPGA firmware without manually power cycling the router.
Firmware upgrade on BOOT FPGA doesn’t require the physical intervention to power cycle the device, rather it can be doable via a CLI command.
<-- Firmware upgrade is required for RE BOOT FPGA and BIOS ROM

Upgrade initiated. Please check status using show system firmware cmd. When programming finishes for all initiated upgrades, please reboot system to load/see new version.
<-- Verify the status after installation, and before the power cycle.

BOOT FPGA Firmware shouldn't be installed even though it says installed successfully.
Installs only after power cycle of the router.
Instead of manual power cycling of the router, soft power cycling is available from the router via the following command
request node power-cycle re0 <<<< You can mention re0 or re1 depending on the router.
