I bought it from eBay. It's brand new when I purchase it. I changed the console cable, it's not working. I check all the lights, it's green. I try to connect it with my computer and use it as hub. It works fine. But, I just can't get access to it. The IOS image is already install when I buy it. I forgot to mention. I was able to access to the switch few weeks ago. I haven't changed anything or do any upgrade. It's so strange.
