follow three major steps.

STEP (B): Upgrade the boot loader
STEP (C): Upgrade the firmware code
Important: During the boot loader upgrade process, the Main Unit's
settings are not accessible. Therefore, please note down your Main
Unit's IP address before starting the boot loader upgrade.
STEP (A): Remove all Stacking Units
1. Disconnect any Stacking Unit(s) from the Main Unit.

recommended to upgrade the boot loader by connecting the cross-over
network cable between the Main Unit and the PC with Paragon Update
to avoid any potential risk.
1. Download the appropriate firmware version from Raritan's website.
See STEP 1: Download the Latest Firmware and Release Notes

successfully.
