How to upgrade Asic FW on Spine module on CS7520 Switch

Good morning, one of spine module dead. I could not find the spine module with the same FW. So i bought a part that has older rev. Currently, 5 spine modules has rev A6 (original), a replacement spine module is rev A5. The Switch is running but could not detect nor assign the GUID nor auto upgrade the Asic FW.
Is there a way to upgrade Asic FW for the Spine module (Rev. A5 to Rev A6). I already download Rev A6 .bin image but dont know to do the upgrade. Thanks.

A5 and A6 is HW version, can’t be upgraded.
