Asa 5520 Configuration

Hello experts,
I am new to Firewall configuration and I am having some issue trying to configure my 5520.
Basically it says that the outside interface is down and I don't understand why.
I run the no shutdown command on both internal and external interfaces but no changes.
The router ip address is 10.0.0.254 and it is a dsl broadband with static public ip

Here is my configuration

Result of the command: "show running-conf"

It could be a cable or an upstream port problem.

It seems physical layer problem

- Get the upstream device (router) and firewall outside interface Duplex / speed settings be same

- connect HUB/switch between router and firewall

- Try with changing to other interface (both sides)

- change physical cable connection

- remove upstream router and connect your laptop and see interface status

pls copy here :

- sh interface gig 0/0
- sh arp
