I have an AG638B FC disk enclosure from an EVA4400 system with a defective I/O module. The module shows all green LED and also the ID is diplayed correctly but it has no link on both FC channels.
So I attached a serial cable to the MFG port of the I/O module and got a response at 115200 baud.
My problem is that I have no idea what commands can be used there. I tried everything I know and all letters from the alphabet... "illegal command" is the answer. I even tried all ESC sequences.
Does anyone know something about the serial commands of this I/O module?
(Of course I will replace the I/O module soon... but maybe there is a chance to bring it back to life)
