When trying to upgrade the proxy you will get the fallowing errors System Error: An internal error when installing the system image (on SSH console) Error writing system image to bootable partition: 0x10002:0x0 on serial console.
If the proxy has only one SSD then RMA needs to be initiated, if the proxy has more than one SSD the primary SSD must be remove and try to boot with secondary SSD, if the primary SSD is detected as failure then RMA must be initiated.
