Husam,
I had similar issue, and couldn't get into console via using what's provided in the box. ( I had COMM/usb to DB9 Male in the box).
I had to buy 'DB9 Female - DB9 Female', connect that to my PC and verify the COMM port number under 'My Computer>manage>Device>Com Ports', worked fine.
After that I gave Ip address to MGMT port, and never had to use that DB9 anymore.
This may work for you as well.
