@LodeRunner and @fohdeesha Thank you both for the responses! I will see what I can do about copying the data from flash and copying the keys out. I purchased the switch for less than $50, so it's not a big loss if I can't get it working. I'll let you know if I have any success. If I'm successful with that, do you expect the keys will also work for the switch @LodeRunner has? I'm certainly happy to share the keys with him if I can successfully extract them from this switch.
