Once you find these configuration values in the disassembled bootloader they can be changed to appropriate values for the Quanta chassis and re-compiled. I received an estimate from a firmware engineer of approximately $2000 USD for this amount of reverse engineering, which I'm not willing to spend for a management port I never use on a $300 switch. +Sadly neither of these are fixable without disassembling the bootloader (the Brocade bootloader is what's responsible for initializing the PHY.
