Webcenter Content can be accessed using the URL - http://<hostname>:<port>/wc (Port by default is 16200 for content). If the server has started without errors you should see the Webcenter Content login screen and homepage after you have logged in. In case the UCM_Server1 has not started in your admin console, try starting the managed server using command and you will see errors if any. Hope this helps.
Error 404--Not Found.
After visited Technology Blogs: Oracle WebCenter Troubleshooting Tips I found the solution to start. Now I can continue.
